LavaGolem

Alchemist Golem

A fourth golem — crafted with a Brewing Stand in the center — runs your brewing stands so you never stand there swapping bottles again.

One chest holds everything. Glass bottles, nether wart, blaze powder and your ingredients all go into a single [Brew] container; the golem works out what each item is for. It fetches its own water (a source block, or a water cauldron that rain and dripstone refill for free) and delivers the potions to [Output].

• You set the recipe by stocking the chest — it brews in stages and keeps going while the ingredients last. Nether wart, blaze powder and redstone? Long Strength. Add gunpowder and you get a splash long Strength.
• It only starts a batch it can finish. The awkward base is a means to an end, so with no target potion available it won't touch the water — and it never files an awkward base away in [Output] as if it were done. Drop a potion back into [Brew] and it picks it up to carry another stage.
• It won't brew more than [Output] can take — potions don't stack, so two free slots buys two bottles, not three.
• Smart about blaze powder — it's both the fuel and the Strength ingredient, so only one pinch is ever staged as fuel (that's 20 brews) and the rest stays for potions. Give it blaze rods and a crafting table and it grinds them itself, using the real vanilla recipe.
• Pick what it may brew — its menu lists every potion as the real potion item; click to switch each one, and each modifier, on or off.

Per-golem container tags

The tags in the config are now only the defaults. Every station menu shows the containers that golem looks for: right-click to type its own tag, left-click to reset. So a brewery and a smeltery can stand side by side without fighting over one shared [Output] — point one at [Potions] and you're done. Any language works, and the tag is matched exactly as written on the container (the brackets are just a convention, not syntax).

An off switch

Every golem's menu now has a power button: it stops where it stands until you switch it back on. Handy while you rebuild a station.

• Only the Lava Golem is on fire now — it's the one hauling lava. The Alchemist trails brewing particles. Both purely visual: no resource pack, no damage.
