Cauldron++
by redColmula55
Cauldron++ brings a historical brewing system back to modern Minecraft, letting a cauldron hold water, lava, powder snow or a potion.
What it does
A cauldron filled with a material can be used to brew potions. Adding a brewing ingredient changes the potion type the cauldron produces, and the list includes wart, blaze powder, ghast tear, sugar and magma cream. Right-clicking a cauldron of water or potion with a glass bottle fills the bottle, and right-clicking it with arrows fills up to 16 tipped arrows per level.
Cauldrons holding lava emit light level 15 and hurt a player standing inside, while a cauldron holding powder snow freezes one. Water can dye leather armor. The mod runs on Fabric and Forge, and Fabric API must be installed alongside it on Fabric.
