On Fire!

On Fire! is a debuff which causes the afflicted NPC or player to lose 8 health per second while not regenerating health. This debuff can be canceled prematurely by jumping into Water, or by pouring a Water Bucket over the player's head. If the player is under the effects of the Obsidian Skin Potion, Lava will not burn them.
