Chaos druid warriors can be found in Yanille Dungeon, which requires 40 Agility to access. Alternatively, they can be found on the Slepe church's roof.
They drop herbs frequently, so are useful for players seeking to train Herblore. They are a more powerful version of Chaos druids and drop more ingredients than their lower-levelled counterparts.
There is a zamorakian altar located in the area they inhabit, but using it drops the player down into a pit of level 64 poison spiders and the drop results in the player taking damage (up to 15 hitpoints).
