Chambers of Xeric
Chambers of Xeric is a raid which consists of multiple boss and puzzle rooms. The raid scales up per player, increasing stats of the bosses. You can also set a custom scaling on the raid interface before you start.
- The custom scaling is in addition to the number of players. ie. Setting the scaling to 7 with 2 players in the raid will give you a 9-man raid.
