Leech

Leeches (Hirudinae Acidia) are found in Morytania in the Mort Myre Swamp and the Haunted Woods east of Canifis.

These creatures don't appear on the minimap and drop nothing when killed. Leeches do not deal a particularly large amount of damage. They can be dangerous, as they drain stats upon landing a successful hit. They generally serve as a distraction to players who are hunting other monsters like vampires or ghasts, or who are trying to travel through areas that leeches are found.
