Ominous Alchemy

Turns the cauldron into a real brewing station. Fill it with water, heat it over fire or lava, charge it with Ominous Bottles, and toss in recipe ingredients to craft powerful multi-use flasks.

How to brew

1. Right-click a cauldron with a water bucket
2. Keep a fire, soul fire, campfire or lava block underneath until the water boils (6 seconds by default)
3. Throw in an Ominous Bottle — up to 3 charges per cauldron
4. Add the recipe ingredients (sugar, wind charges, blaze powder, echo shards and more)
5. The finished flask pops out of the cauldron

Recipes

Every recipe is configurable — ingredients, effects, durations, colors and flask charges.

Volatile reactions

Mixing incompatible ingredients is dangerous:

• Explosion pairs — a miniature wind explosion that throws entities around
• Gas pairs — a lingering toxic cloud that poisons and slows
• Summon pairs — a Corrupted Bogged claws its way out of the brew

Flasks

Flasks are multi-use potion flasks. Right-click one to spend a charge; each recipe configures how many charges it starts with.

Commands

Cauldron states persist across restarts. Verified on Minecraft 1.21.11, 26.2, and 26.3.
