Boss Altar

Boss Altars are spread out around the provinces and allow the player to access special arenas where they have the chance to fight and defeat a boss. Players are required to sacrifice a specific type of item to go through, though there are always clues around the altar about what type and quantity of items are needed. Only one sacrifice is needed for groups of any size, as once the sacrifice has been completed, all players close to the altar will be teleported to the arena.

The boss has a good chance to drop a few very powerful items. However, it can only be fought once per payment. When the boss is killed, it won't respawn until the player leaves and pays the fee again. Using /class will not make it spawn again.

Boss Altars
Here is a list of all currently known Boss Altars, sorted by minimum recommended level (based on the level requirement of the dropped boss altar items, although they can be challenged a few levels earlier successfully in most cases).
