OSRS Chambers of Xeric Combat Rooms Guide: Ice Demon, Shamans, Mystics & Guardians

Overview: Chambers of Xeric Combat Rooms

Chambers of Xeric builds each raid from a random selection of rooms, so 6 combat encounters in our index can appear in front of you and you do not get to choose which. That is the defining feature of the raid — you have to be competent at all of them rather than good at one.

Every room shares the same access requirement and feeds the same points total, which is why the reward column below looks similar across rows. The points, not the individual room, are what produce a purple.

The Rooms

Points come from damage dealt and are lost to deaths, so a room you clear slowly costs less than a room you clear fast and die in. Learn the rooms you are worst at rather than optimising the ones you already like.

The combat rooms do not test the same thing, which is why gear that carries you through one can leave you stuck on another. Each fight's defining demand:
