Our poison probablity in a coal mine

Stankers | RuneScape Wiki | FANDOM powered by Wikia

Stankers is a dwarf who runs the coal trucks.Players may place their coal into the trucks and collect them later at the coal truck depot. Players may also obtain a poison chalice from him for free. In the Seers' Village Tasks you have to get a poison chalice from him to give to King Arthur. He holds 30 free samples of these chalices.
