Damis

Damis is one of the four guardians of the Diamonds of Azzandra, fought only when doing the Desert Treasure quest. He has two forms, the first being rather easy and level 103, the second being very tough indeed.

He can be fought in the Nightmare Zone after the quest is complete.

Locations
West of the Fishing Guild, in the fenced area, down a ladder which requires the Ring of Visibility to see. When approaching Damis's location, the player will be told that they hear a voice from the walls telling them to turn back.

Strengths and weaknesses
In his second form, Damis drains prayer very quickly. A simple strategy, if one has the money, is to use magic against him while praying. It is not recommended to use melee, as he is incredibly strong against it. It is possible, but is much more expensive due to the prayer potions used. An effective method to defeat him is to use magic from a distance. This can be accomplished using Snare/Entangle, or trapping him behind one of the Giant Rats in the south-east corner of the dungeon. While this method works with the Giant Rats, it will not work with the skeletons of the dungeon.
