Cataclysm minibosses are the strong L_Ender’s Cataclysm mobs that guard the structures of the Eight Sins. Players meet them on the way to the Sins in Act III, but no quest requires killing them.
Every one of them has a level floor of 200, the highest level a player can reach, so they are always level 200 (see Mob Levels). None has a damage cap.
The Cataclysm minibosses, in the order of the table below.
Cataclysm’s config multiplies most of their base health and attack damage by 1.2 before the level bonus applies; Coralssus and The Watcher have no multiplier.
Each structure sits in the dimension of its Sin, reached with that Sin’s eye (see Cataclysm Dimensions). Ignited Revenants also spawn in Better Fortresses’ Nether Fortresses.
