Derwen is an ancient servant of Guthix. He takes great interest in Justiciar Zachariah and Porazdir, attempting to keep a balance between them. He has to be defeated in order to obtain some ent's roots for Kolodion's spell during The Mage Arena II miniquest. In order to summon him, players have to use an enchanted symbol to locate him, similar to using an enchanted key or strange device.

When fighting Derwen, he can use a special attack which will release multiple balls of energy in the area around him. These balls of energy will heal Derwen for five Hitpoints every few seconds. They can be destroyed by the player, having 20 hitpoints each.

Fighting Derwen

A player fighting Derwen.

Derwen can only be harmed by the Claws of Guthix spell. As such, a Guthix staff or void knight mace is required to defeat him.
