Drowned Trident Farm in a River or Ocean

What You Get (Drops, XP, and Why This Farm Is Worth Building)

A drowned trident farm is a specialized hostile-mob farm built in or near water (river or ocean) that focuses on spawning drowned and killing them efficiently so you can collect their drops. The main reason most players build this is to obtain tridents, but the farm can also provide a steady stream of general drowned loot.

Primary rewards you can expect:

Tridents: Drowned are one of the few sources of tridents. However, the rules are different between editions (Java vs Bedrock), and the realistic trident rate depends heavily on which edition you play and whether you’re killing naturally spawned drowned or converted drowned (more on that later).

Gold ingots: Drowned have a small chance to drop gold ingots. Over time, this adds up and can be a nice bonus.

Fishing-type drops: Drowned can drop items like rotten flesh and occasionally other low-tier items, depending on edition and the loot table. The consistent “bulk” drop is typically rotten flesh, which you can trade to clerics or compost (if you want) or use as emergency food.

Experience: If you kill them in a way that counts as “player kill” (or in Bedrock, using certain trident-killer designs), you can also get XP. XP behavior differs by edition and by killing method, so you should decide early whether you want a loot-only farm or a loot + XP farm.

Other practical benefits: Once you have tridents, you unlock powerful gameplay tools such as Riptide travel, Channeling lightning effects (situational), and strong melee/ranged combat options. Tridents also enable some redstone/automation patterns in Bedrock (notably “trident killers”), which can make many other farms easier or more efficient.

Requirements & Version Notes (Java vs Bedrock)

This farm is very sensitive to edition differences. Before you collect materials, decide which edition you’re on and which trident strategy you will use.

Key differences that affect trident farming:

Java Edition: In Java, only drowned that spawn holding a trident can drop a trident, and the trident drop chance is controlled by the usual equipment-drop rules (affected by looting). This means that killing large numbers of drowned does not guarantee tridents unless a portion of them spawned with tridents. A Java trident farm is therefore best built where drowned spawns are plentiful, and it benefits significantly from a player kill with Looting III if you want the best results. Converting zombies into drowned in Java is generally not a strong trident strategy because converted drowned do not suddenly “gain” tridents; they keep what they had.

Bedrock Edition: In Bedrock, drowned can drop tridents under different rules than Java, and Bedrock players commonly use trident killer systems (a trapped trident moved by pistons) to get drops/XP in an automated way that still counts appropriately for many mechanics. In Bedrock, it is also common to use zombie-to-drowned conversion strategies as part of efficient drowned farming in general. However, exact drop behavior and whether conversion-based setups are optimal can vary by version. If you’re on Bedrock, confirm current behavior for your game version if you want guaranteed expectations.

Spawning environment notes:

Rivers: Rivers are popular because they are narrow and easier to control and spawn-proof around. However, rivers often run through many adjacent biomes and caves, which can impact hostile mob caps and rates if you do not spawn-proof.

Oceans: Oceans provide larger water surfaces and can be very good for drowned spawning. The tradeoff is that you may need more spawn-proofing (and you must manage other water mobs and the large number of caves that can load under oceans).

Difficulty: Drowned spawning and behavior can be affected by general hostile mob rules. You should build and run the farm on a difficulty that allows hostile mobs to spawn (not Peaceful).

Performance considerations: Water flow, bubble columns, and large numbers of entities can affect performance. If you play on a server, check any mob limits or farm rules.

Materials (Example Shopping List)

The exact blocks count depends on your footprint and whether you build in a river (smaller) or ocean (bigger). The list below is for a typical “water-channel + kill chamber + storage + AFK platform” farm. Choose materials you like; function matters more than aesthetics.

Building blocks (several stacks): stone, cobblestone, deepslate, or any solid block for walls, floors, and spawn-proofing.
Slabs (at least a stack): for spawn-proofing surfaces and making safe walkways.
Trapdoors (16–64): useful for pathing control, water control, and compact channels.
Signs or fences (optional): for stopping water flow and shaping channels.
Glass (optional): for visibility around the kill chamber and collection area.
Water buckets (many): to create source blocks and manage flow; an infinite water source helps.
Soul sand (16–64): for a bubble elevator to lift drowned into a kill chamber.
Magma blocks (optional): for a downward bubble column if you want to pull mobs down in a controlled way.
Hoppers (as many as needed; commonly 8–24+): for reliable item collection under the kill point.
Chests (several): storage for rotten flesh, gold, tridents, and other drops.
Item filters (optional): extra hoppers, comparators, redstone dust, repeaters, and building blocks if you want sorting.
Campfires (Java/Bedrock, optional): can be used as a passive kill method in some designs, though “player kill” benefits may be lost.
Weapons: ideally a Looting III sword (Java) for improved trident odds when applicable.
Lighting (optional): torches or other lights for your work area (do not light the intended spawn water surface if that would reduce spawns in your design).
Ladders or scaffolding (optional): for building the AFK platform.
Name tag (optional): for keeping a mob for testing mechanics (not required).
Bedrock only (optional): pistons, redstone blocks, observers: if you plan to build a trident killer style kill chamber.

How the Mechanic Works (Spawning, Movement, and Killing)

This farm uses a simple loop: drowned spawn in valid water spaces → water currents guide them → they are lifted or moved into a kill/collection point → drops are collected by hoppers.

1) Drowned spawning basics (high-level):

Drowned are hostile mobs that spawn under rules that depend on edition and biome. In general, they spawn in water in certain biomes (rivers and oceans are commonly used). For the purposes of building a farm, what matters is that you provide a large area of valid spawning water and keep the player positioned so that spawning is allowed and efficient.

2) Spawn conditions and player distance:

Hostile mobs typically only spawn at a distance from the player and despawn (or fail to spawn) if too close or too far, depending on the edition and current rules. Since these rules have changed across versions and can be affected by simulation distance (Bedrock) or render distance and server settings (Java), you should treat the AFK platform height as something to tune during testing rather than a single universal number.

3) Water currents and entity movement:

Drowned swim and can be pushed by flowing water. You can shape a “spawning pool” or “spawning lanes” so that any drowned that appear are gently carried into a central channel. From there, a bubble elevator (soul sand) can lift them vertically into a compact kill chamber. The big advantage of bubble elevators is reliability: they don’t require complicated pathfinding, and they move mobs even if the mobs are not cooperating.

4) Killing and drop collection:

You have three broad kill options:

Player manual kill (best for Java trident odds): You bring the drowned to a one-block hitbox point (or small kill cell) and kill them with a Looting sword. This usually maximizes the chance of getting tridents in Java (when a trident is eligible to drop).

Automated environmental kill (simple, but may lose “player kill” benefits): Campfires, fall damage, magma, etc. This can be easier and safer but may reduce the value if you want XP or looting-based improvements.

Bedrock “trident killer” (popular for automation): A thrown trident is held in a killing area and moved by pistons so it repeatedly damages mobs. This approach is Bedrock-specific in practice and is not the same as Java’s rules and redstone behavior. If you play Bedrock and want a mostly AFK kill system, this is the common path.

5) Why spawn-proofing matters:

The game has a limit to how many hostile mobs can exist around players (the exact details depend on edition and version). If caves, shorelines, or dark land areas nearby are spawning other hostile mobs, they “steal” the hostile mob capacity and reduce your drowned spawns. Spawn-proofing (lighting, slabs, removing dark spaces, or building the farm away from land) can dramatically improve rates.

Step-by-Step Build (8–12 Detailed Steps)

Step 1: Pick a location and define your goal (Java looting kill vs Bedrock trident killer). Choose a river or ocean area with minimal nearby land if possible. In a river, look for a long, straight stretch so you can shape water flow easily. In an ocean, try to build over deeper water to reduce land-based hostile mob spawns near your farm. Decide early whether you want to stand at the kill chamber and manually kill (common for Java) or whether you want a more automated kill system (common for Bedrock). This choice affects the kill chamber design and your AFK spot placement.

Step 2: Survey and prepare the surrounding area to improve rates. Before placing your main structure, fly/boat around (or swim) and note nearby caves, ravines, and shorelines. For best results, reduce competing spawns. Practical methods include: lighting up nearby caves you know are within range while you AFK, placing slabs on exposed dark land, and avoiding building too close to big cave systems. If you cannot realistically spawn-proof everything, consider building farther offshore (ocean) or using a higher AFK point to reduce loaded caves, but remember that going too far can also reduce spawning if mobs are outside active spawning ranges for your edition/version.

Step 3: Build the spawning area “pool” or “lanes” in the water. A straightforward approach is to create a rectangular or oval “spawn zone” where drowned can spawn, then shape gentle currents toward a central collection channel. In a river, you can use the river’s natural boundaries and add walls on the sides to prevent mobs drifting away. In an ocean, you may want to build low walls (solid blocks or glass) around the perimeter to keep drowned inside your collection footprint. The goal is: any drowned that spawns should eventually be carried by currents to one point. Make the floor consistent (for example, flatten it to a single depth) so you can predict where water flows and where mobs will drift.

Step 4: Create water currents that push drowned toward your intake channel. Use solid blocks, trapdoors, and careful water placement to ensure most water blocks flow toward one direction. Often, builders make a series of “lanes” where each lane pushes mobs toward a main channel. If you’re new to water engineering, work slowly: place a few water sources, watch where items drift, and adjust. Dropping a few items (like seeds) into the water is a simple way to visualize current direction. Your target is a reliable “conveyor belt” effect that moves drowned without requiring them to pathfind.

Step 5: Build the intake and pre-sorting funnel so mobs don’t get stuck. At the point where currents converge, build a one- or two-block-wide channel leading to your bubble elevator. Add walls high enough that drowned don’t swim out. If the intake is too wide, mobs may swirl and fail to enter the elevator. If it’s too narrow or has awkward corners, mobs can jam. You want a smooth entry where the current points directly into the elevator column. If you notice frequent clumping, consider widening the approach slightly and then narrowing right at the entrance.

Step 6: Construct the bubble elevator (soul sand) and confirm it is a true bubble column. Dig/build a vertical shaft from the intake up to your intended kill chamber height. Place soul sand at the bottom. Then ensure the elevator is made of water source blocks from bottom to top. This detail is crucial: in many cases, if parts of the column are flowing water rather than source water, the bubble elevator won’t work consistently. A common method is to fill the entire column with kelp from bottom to top (kelp converts many water blocks into sources), then break the kelp and place soul sand at the bottom. If you’re unsure whether it’s functioning, throw an item into the column: it should rise quickly and smoothly to the top.

Step 7: Build the kill chamber as a compact containment cell with a controlled kill point. At the top of the bubble elevator, create a small holding area where drowned emerge. You typically want them to end up in a 1x1 or 2x1 space where they can’t escape, and where you can either hit them safely (manual kill) or let an automated kill method do its work. Add a ceiling to prevent drowned from swimming upward and wandering. If you’re doing manual kills (especially in Java), include a barrier like a slab or fence line that prevents them from hitting you while still allowing your weapon to reach them through the gap. Ensure there is no open water route out of the chamber.

Step 8: Install item collection directly under the kill point using hoppers and chests. Most reliable designs place hoppers (a line or a 2x2/2x3 grid) under where drowned die so all drops fall onto hopper hitboxes. Funnel those hoppers into one or more chests. If you expect a lot of drops (especially rotten flesh), consider a double chest array or connect to a bulk storage system. If you want sorting, add filters later, but start with a simple “everything into chests” approach to validate that the farm works. Make sure the hoppers are not locked by powered redstone unless you intended that.

Step 9: Add your chosen killing method and safety features. For Java manual killing, create a small player spot where you can swing safely. Consider adding a door, fence gate, or a small corridor so you can enter without letting mobs out. For Bedrock trident killer, build the piston-driven chamber that keeps a thrown trident moving where mobs are held; make sure you can retrieve/replace the trident and that the trident doesn’t despawn (Bedrock trident killer behavior is version-sensitive, so test carefully in your exact version). For environmental kills (campfires, fall damage), verify that items are still collected properly and that mobs actually die at a good rate without clogging the chamber.

Step 10: Build an AFK platform and spawn-proof the immediate area you will keep loaded. Place an AFK platform at a height and position that keeps the spawning area active but reduces unwanted spawns elsewhere. Because spawn radii and despawn behavior differ by edition and can be influenced by simulation distance (Bedrock) and server settings, the “perfect” AFK height is something you should tune. As a starting point, many players place the AFK platform well above the farm so the main loaded area is mostly water and your farm footprint rather than land caves—but you must still verify that drowned are spawning and reaching the kill chamber. Add railings or slabs to prevent accidental falls, and add a small shelter to avoid being attacked by phantoms if you are on a version where phantoms are a concern and you have not slept.

Step 11: Tune the water flow and fix clogs by observing mob movement for several minutes. Stand where you can watch the spawning area and the intake. If drowned spawn but don’t reach the elevator, your currents need adjustment: add guide walls, remove eddies, and ensure the final current points directly into the bubble column. If drowned reach the elevator but fail to rise, you likely have non-source water blocks in the column or the soul sand is not correctly placed. If drowned arrive at the kill chamber but build up too fast, you may need a faster kill method or a larger holding cell that prevents entity cramming issues (exact cramming behavior depends on edition rules).

Step 12: Add quality-of-life upgrades once the base farm works. After you confirm you are getting consistent kills and items are reaching storage, you can expand storage, add item filters (rotten flesh vs valuables), add an on/off switch (to stop water or disable the elevator), and build safe access tunnels. If you play Java and want better trident odds, ensure your killing method counts as a player kill with a Looting III sword whenever possible; if you play Bedrock, consider integrating a well-tested trident killer pattern appropriate to your version.

Testing Your Result (How to Verify It’s Working Correctly)

Testing should be done in a structured way so you can identify what part of the chain is failing: spawning, transport, kill, or collection.

1) Spawning test: Go to your AFK position (or intended operating position) and wait a few minutes. Then briefly return to the spawn area (carefully) and look for drowned presence or signs of movement. If you see very few drowned, the issue is usually competing spawns (nearby caves/land), incorrect AFK placement (too close or too far), or simply a low-efficiency spawn footprint.

2) Transport test: Drop a few items into different parts of the spawn pool and watch if they drift toward the intake. Items are a good proxy for current direction. If items get stuck in corners, drowned will too. Fix corners by filling them in, rounding with blocks, or changing where you place source water.

3) Elevator test: Throw an item into the bubble column. If it rises smoothly from bottom to top, the column is likely correct. If it stalls or rises only partway, convert the column to source blocks (often by kelp) and confirm the soul sand is at the bottom.

4) Kill chamber test: Confirm that drowned are held where you want them and do not escape. Check that you can kill them safely (manual) or that your automated method actually finishes them. If they accumulate endlessly, you risk performance issues and reduced rates.

5) Collection test: Kill a few drowned and confirm items appear in the hoppers/chests. If drops land outside hopper range, add more hoppers or adjust where mobs die. If items are burning or being destroyed (campfire edge cases, magma, or entity collision with blocks), adjust the kill point so drops fall cleanly onto hoppers.

6) Trident expectation test (edition-specific): In Java, do not judge the farm by “tridents per minute” too quickly. Tridents only come from drowned that spawned holding a trident, so trident drops can be streaky. Use Looting III and run the farm long enough to get a meaningful sample. In Bedrock, if you built a design intended to produce tridents reliably, validate in your exact version with a timed run and compare to expected behavior for that edition/version.

Common Mistakes (And How to Fix Them)

Mistake 1: Building the bubble elevator with flowing water instead of source blocks. Symptom: mobs/items don’t rise or rise inconsistently. Fix: convert the entire column to source blocks (commonly using kelp), then place soul sand at the bottom.

Mistake 2: AFK platform positioned so the farm footprint is not the main spawnable area. Symptom: very low drowned rates and lots of other hostile mobs in caves or on land. Fix: move the AFK spot and/or spawn-proof around the farm. In oceans, moving farther from land can help; in rivers, spawn-proofing nearby caves is often necessary.

Mistake 3: Expecting Java drowned to drop tridents even if they are not holding one. Symptom: lots of drowned kills but no tridents. Fix: confirm you are on Java and understand the rule: only drowned that spawn with a trident can drop one. Improve odds by increasing spawns and using Looting for eligible drowned.

Mistake 4: Intake channel too wide or too chaotic, causing mobs to swirl and never enter the elevator. Symptom: drowned cluster near the entrance. Fix: straighten the approach, add guide walls, reduce turbulence, and ensure the final current points into the elevator.

Mistake 5: Kill chamber allows drowned to hit you or escape. Symptom: unexpected deaths, drowned leaking into surrounding water, or drowned roaming. Fix: add a solid barrier, use slabs/trapdoors for controlled openings, raise walls/ceiling, and ensure there is no water route out.

Mistake 6: Collection system not aligned with the death location. Symptom: items floating away or collecting poorly. Fix: move the kill point so mobs die directly above hoppers, or expand hopper coverage.

Mistake 7: Overloading the area with entities and causing lag. Symptom: stuttering, slow item collection, and reduced spawn rates. Fix: speed up kills, add better throughput, reduce unnecessary water simulation, and use fewer loaded chunks while AFK.

Variants & Upgrades (Choose Based on Your Edition and Goals)

Variant A: “Manual Looting Kill” (Recommended for Java tridents)

This variant brings drowned into a tight chamber where you kill them with a Looting III sword. The benefit is maximizing trident drop chance when a trident is eligible to drop. You can also gain XP. The downside is it’s not fully AFK; you must actively kill unless you add a semi-auto click method (which may violate server rules) or you use other strategies that still count as player kills.

Variant B: “Campfire or Fall-Damage Kill” (Simple and low redstone)

This variant uses environmental damage to kill drowned after they arrive. It’s easy to build and can be fairly safe. The tradeoff is that you may lose player-kill benefits such as Looting and consistent XP gain, depending on edition and exact kill method. If your goal is mostly rotten flesh and occasional valuables, it can still be worthwhile.

Variant C: “Bedrock Trident Killer Chamber” (Automation-focused)

In Bedrock, many players use trident killers to automate kills while still getting useful drops (and often XP). If you choose this route, build it only after confirming you understand current Bedrock behavior for your version. Ensure you have a safe method to insert the trident, keep it from despawning, and retrieve it if something goes wrong. Also plan for overflow: if your trident killer can’t keep up with spawns, mobs will accumulate and reduce performance.

Upgrade 1: Expanded spawn footprint + controlled currents

Once the base farm works, increasing the size of your spawning area can increase drowned throughput. The limiting factor is often how many drowned you can transport and kill without clogging.

Upgrade 2: Better spawn-proofing (highest impact in many worlds)

Even a “perfect” farm design underperforms if the mob cap is filled by mobs in caves. Invest time in spawn-proofing within the relevant area around your AFK spot.

Upgrade 3: Item sorting and overflow protection

Rotten flesh can fill storage quickly. Add an overflow system (extra chests) or a filter that routes rotten flesh into a separate bulk storage. If you want, you can add a disposal line (for example, a lava disposal) but be careful not to accidentally destroy valuables like tridents.

Upgrade 4: Safer access and maintenance corridors

Add sealed tunnels from shore or from your base, plus ladders/scaffolding to the AFK platform. This reduces accidental drowning and makes it easier to repair the elevator or channels.

Upgrade 5: Lightning rod integration (situational)

If you are experimenting with Channeling tridents or want lightning effects nearby, you can add lightning rods for controlled strikes. This is more of a thematic upgrade than a rate upgrade, and it depends on weather and mechanics that may not be helpful for most farms.

Performance & Safety Notes (Keep It Efficient and Don’t Die)

Performance tips:

Water-heavy farms can be demanding because of entity counts and item movement. Keep the kill speed high so mobs don’t accumulate. Avoid leaving large numbers of items floating in water; use hoppers and ensure they feed into chests quickly. If you notice lag, reduce the farm footprint, reduce loaded chunks, or increase kill throughput.

Safety tips:

Drowned can carry tridents and can be dangerous at close range, especially if they can throw. Ensure your kill chamber prevents line-of-sight attacks where possible, and consider a barrier that blocks projectiles if your design and edition/version allow drowned to throw effectively. Always include an escape route from your AFK platform. If you operate at night and you haven’t slept, consider phantom risks depending on your version and settings.

Server/community rules:

Many servers restrict AFK clickers or entity-heavy farms. Confirm rules before building large-scale versions.

FAQ

Can I build this in a river, or is an ocean always better?

You can build it in either. Rivers are often easier to control because the footprint is smaller and you can wall it off quickly, but they may be close to caves and land spawns that reduce efficiency unless you spawn-proof. Oceans give you more space and often fewer nearby land spawns if you build far offshore, but oceans can also hide many caves underneath, and the build may be larger and more time-consuming.

Why am I getting lots of drowned but no tridents?

On Java, this is commonly normal if most drowned are not spawning with tridents. In Java, drowned can only drop a trident if they spawned holding one, and Looting improves the chance when eligible. On Bedrock, rules differ and tridents may still be rare depending on your version and kill method. The most reliable fix is to verify your edition rules, confirm your kill method qualifies for the drops you want, and then run a longer test session to get a meaningful sample size.

Does Looting increase trident drops?

Java:

Do converted drowned (from zombies) drop tridents?

Java:

How high should my AFK platform be?

There is no single universal height that is always correct because effective spawning depends on edition, version, server settings, and simulation/render distance. The practical approach is: place an initial AFK platform above the farm, run timed tests, and adjust. If you’re getting poor rates, you may be loading too many caves/land areas (move farther from land or higher) or you may be too far from the spawning area (move closer). Test and iterate.

Why are drowned getting stuck and not entering the bubble column?

This is almost always a water-current geometry issue. The final blocks before the elevator must have a clean, direct flow into the column. Fixes include narrowing the entrance, adding guide walls, removing corner pockets where mobs swirl, and ensuring the elevator entrance is not offset or recessed in a way that breaks the current.

Why does my bubble elevator sometimes stop working?

The most common cause is that the elevator column is not entirely made of source blocks. Rebuild it using a method that guarantees source blocks (often by growing kelp through the column, then removing it). Also confirm the correct block at the bottom: soul sand for upward bubbles, magma for downward pull.

Is this farm dangerous in hardcore?

It can be, especially if drowned can attack you in your edition/version and if your kill chamber exposes you to trident throws or melee hits. In hardcore, prioritize safety: sealed kill chambers, controlled hit windows, strong armor, and an emergency exit. Also ensure you cannot be knocked into deep water where multiple drowned can surround you.

Can I run this farm fully AFK?

Bedrock:

How do I keep storage from filling with rotten flesh?

Add a dedicated bulk chest line for rotten flesh, use an item filter to separate it from valuables, and implement overflow protection. If you choose to dispose of excess, ensure your disposal cannot destroy tridents or other valuables by mistake (for example, filter valuables into a protected chest before sending bulk items to disposal).
