A "drops farm" converts mob spawns into resources for sale. Here are the optimal designs for the common spawner types on DonutSMP.

Optimal layout (universal)
The standard design works for any spawner:
Layer 1 — Spawning chamber
- 9×9 cube
- Spawner suspended in center via brick blocks
- Slime block walls (mobs slide off)
- Dark (light level 0)
Layer 2 — Water collection
- Floor of spawning chamber has water flowing toward center hole
- Mobs get pushed by water to a central point
Layer 3 — Kill chamber
- 1-block opening below water flow
- Mobs fall 22 blocks (damage them to ~half HP)
- Land in a 1-block kill area where you finish them with sword
Layer 4 — Hopper collection
- Hoppers under kill chamber
- Hopper chain to double chests
- Auto-pulls all drops
Layer 5 — Storage / auto-sell
- Chests hold drops
- Manual /sell at end of session, or
- Hopper trade with /sell NPC (if server supports)
Stacking multiple farms
DonutSMP has spawn-rate caps per chunk. To maximize output:
- Spread farms across 4-6 chunks (each one its own farm)
- Be within render distance of the center chunk to load all of them
- Each farm operates independently at full spawn rate
5 stacked farms = ~5x the output of one farm.
Hidden farms — security
Other players will:
- Find your farms via tracking your movement
- Steal drops if not protected
- Sometimes destroy spawners
Protections:
- Build deep underground or sky-high (Y > 200)
- Don't tell anyone the coords
- Use redstone alarms for intruder detection (high-end)
- Build multiple decoy bases
Auto-AFK trick
Some players use auto-clickers (allowed? check server rules) to automatically kill mobs without manual input. Lets the farm run while you're truly AFK.
Common setup:
- 1-block tall kill chamber
- Mob's head is right at attack range
- Auto-clicker hits sword every 600ms
Check server rules before doing this. Some servers ban auto-clickers.
Selling drops
Items per hour (skeleton spawner example):
- 7,200 bones → /order at 170 each = 1.22M coins
- 4,800 arrows → /sell at 60 each = 288k coins
- Total: ~1.5M coins/hour
Sell schedule:
- Active sell during play sessions
- Hopper-to-NPC auto-sell during AFK (if supported)
Where to buy spawners
- In-game shard shop — 1,500 shards each, 25 hours of grinding
- /ah — 30-200M per spawner depending on type
- Donut Depot — Skeleton at $0.49 (cheapest path)
Frequently Asked
Can I move a spawner once placed?
Only with silk touch pickaxe (extremely rare on most servers — usually impossible).
Do farms work while I'm offline?
No — you (or an alt) must be online and within render distance.
Best alt strategy for 24/7 farms?
2-3 alts on rotating shifts. Each alt loads the farm chunks during their "shift." Alt setup guide →
Can spawners be silk-touched?
Server-dependent. On most, no.
