Acid

Acid is a type of environmental hazard that acts similarly to Lava by dealing heavy damage then burning the player for a bit. Acid is basically a retextured, stronger lava.

Acid also works the same as lava, as anything that gives fire protection will work against acid.

Usage
Acid is recommended to be avoided as it has longer burn time along with heavy damage. Other then that, acid can be avoided with Fire protection from pies or potions.

Acid may also stop the player from fighting droids due to confining a player into a small radius.
