PotionCombine

PotionCombine — shapeless brewing in vanilla cauldrons.

Shift-click ingredients into a water cauldron. If the pile matches a recipe, it brews: bubbles, a progress bar over the water, a spinning bottle to grab at the end. No GUIs, no NMS, no custom items required.

Recipes are plain yml — material or potion ingredients, or other recipes as intermediate steps (phoenix_crown wants a brewed phoenix_elixir first).

Extras, each behind its own config toggle:

• pollution: brews leave grime, a filthy cauldron won't work until scrubbed with a brush
• heat: campfire, magma or lava under the cauldron brews faster (area heat counts nearby sources too)
• synergy: a finished brew pours itself into a neighbouring cauldron waiting on exactly that bottle
• hopper output, per-world filter, per-player cooldown
• progression + /pc journal: an in-game book that fills in as you discover recipes

Needs Paper 1.21+ and Java 21. PlaceholderAPI supported. Locales: en, ru. Small public API with cancellable events.
