Derwen is an ancient servant of Guthix, who takes great interest in Justiciar Zachariah and Porazdir, attempting to keep a balance between them.^[1]

During the Mage Arena II miniquest, he has to be defeated in order to obtain his roots for Kolodion's spell. 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 will cast the Claws of Guthix spell - unlike the version cast by the Guthix battle mages in the Mage Arena, this will reduce your Defence level by 1 + 5%. He can also 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. He can also Tele Block the player for one minute, and cast freezes preventing the player from moving.

Derwen can only be harmed by the Claws of Guthix spell. As such, a Guthix staff, a staff of balance, or the Void Knight mace is required to defeat him. Despite being referred to as an ent, killing Derwen will not count towards an ent Slayer task from Krystillia.

• He replaced the Demon of Balance after the Mage Arena II rework.
• The word "Derwen" means "oak tree" in Welsh.
