Minecraft 26.3 Raid Farms Self-Sustain Ominous Bottles for AFK Loot

Since the 1.21 overhaul changed Bad Omen from an automatic trigger upon killing a Pillager Captain into a consumable item effect, technical builders have had to rethink how automated raid farms operate. In Minecraft 26.3, updated designs now solve the bottle bottleneck by building over the open ocean and using vertical water elevators to create a self-sustaining loop. According to craftdex.net, a single optimised installation works across both Java Edition and Bedrock Edition, producing between 2,000 and 4,000 emeralds alongside Totems of Undying and trading discounts.

The core challenge of post-1.21 raid farming is keeping the player supplied with Ominous Bottles during long AFK sessions without manual restocking. A build documented by farmlymc.com solves this by placing a single villager near the ocean surface and connecting that station to an upper kill chamber using a bubble column. The player rides the water elevator down alongside an armour stand to register near the villager and trigger the raid, then floats back up to the killing floor while drinking the next bottle on the ascent.

How the Bubble Column Loop Works

Once the player reaches the top of the elevator, an auto-clicker swings a sword to sweep the raiders as they funnel into the chamber. As noted by craftdex.net, raid mobs spawn roughly 16 blocks away from the villager across 5 to 7 waves, resetting after each wave is cleared. The farmlymc.com mechanism detects when the final wave finishes and automatically drops the player back down the shaft to start the cycle over, with the defeated captains dropping more Ominous Bottles than the player consumes.

1. Defeat a Pillager Captain at an outpost or patrol to obtain your initial Ominous Bottles.
2. Enter the ocean farm's bubble column alongside the armour stand to descend toward the isolated villager.
3. Trigger the Bad Omen raid waves within the 16-block village detection radius.
4. Drink your next Ominous Bottle while floating back up the water elevator to the kill chamber.
5. Use a sweeping sword attack with an auto-clicker to clear all 5 to 7 waves and collect surplus bottles, emeralds, and totems.

Beyond raw item drops, completing these automated waves awards the Hero of the Village status effect. According to craftdex.net, this buff grants a permanent ~30% trade discount with every villager in the world, and players can stack the effect up to level V for the lowest possible prices in trading halls.

Build Precision and Community Reaction

While the self-sustaining loop removes the need to hunt patrols between sessions, builders warn that the contraption requires strict directional and block accuracy. farmlymc.com cautions that the design is noticeably finicky: placing a single block in the wrong spot, breaking an alignment boat, or standing at an slightly off camera angle will stall the raid detection loop completely. Players are strongly advised to test a world download in creative mode before gathering materials in survival, and to always back up their worlds before constructing complex redstone and entity machines.

Across YouTube tutorials and community builders' hubs such as abfielder.com—where creators share ".schem" and ".litematic" files ranging from technical setups to survival-friendly manors and medieval houses—player reception to modern raid farms is split between relief and frustration. Survival players praise the fact that ocean bubble-column farms make Ominous Bottles self-replenishing again, restoring effortless emerald and totem stockpiling. On the other hand, a common complaint in comment sections is how fragile these setups have become compared to older pre-1.21 stacking raid farms, with many players frustrated that a nudged boat or slight mouse movement during an AFK session breaks the entire machine.
