Toxic Sludge

Toxic sludge is a liquid Material that can be found through out the game. Touching a sufficient amount of it will stain the player (or any other creature), which deals 2% of max HP in damage per second, unless current HP is at or below that amount. Because it stops at =<2% HP, the player will never actually be killed directly from stain damage.

Toxic sludge does not evaporate near normal fire but throwing Kiuaskivi into a pool of toxic sludge will evaporate it, creating toxic gas in the process.

It can be most easily washed off through the use of Water, but other liquids can also be used to overwrite it.

Hiisi enemies are vulnerable to toxic sludge as they take more damage from it than most enemies. They can be killed with it.

Drinking
Drinking toxic sludge will cause the "poisoned" effect, gradually lowering your HP.
