Potent Sulfur

Potent sulfur is a block made from sulfur that produces noxious gas if placed beneath shallow water. Placing a magma block below it in shallow water turns it into a geyser that occasionally erupts and launches entities upward. Placing lava below it causes a constant, non-stop eruption instead.

Potent sulfur drops as an item if mined by any pickaxe. If mined without a pickaxe, it drops nothing.

Potent sulfur generates naturally in the sulfur caves biome in sulfur pools and on the surface in sulfur springs.
