This 2x contested mob spawns deep in Sol eye. He has two adds and does an AOE stun so you must keep your distance from him while fighting. The adds are mezzable so mez adds and kill Caldera first.
Sample Tactic
First thing to know about this encounter is he does spawn in a room with other mobs. You need to clear the area without aggroing Caldera. After you have cleared the mobs around him you can move into the room and pull.
The main tank must position the mob in such a way that the casters and ranged DPS will not get stunned. Caldera does not hit hard but he does do enough damage to require 2-3 healers. Have one healer pre designated to cure the stun on the main tank for aggro keeping purposes. If the main tank loses aggro it is very easy to wipe.
Fight Caldera before his two adds. Use your enchanter or bard to mez his adds until Caldera is dead. After Caldera is dead, rest if needed and then kill his adds. The adds are as difficult as the normal ^^^ Golems in the area.
