Herald of Solithex
Another mandatory boss and the last one in the right wing. This encounter is a public quest as well, so gold bags include the gloves and boots of the Redeye Set.
Caution: The boss room is filled with Old Dwarf Tombstones. Dealing AOE damage around these tombstones will repeatedly spawn level 40 champion mobs.
Tactic
This hero has frontal cleave damage so it should be tanked facing away from the group. Occasionally the boss will cast pools on the ground which deal damage to everyone standing in them. To see the pools video settings need to be set to balanced under Escape -> Video -> Customize -> Effects & Miscellaneous. At 50% health, the boss spawns an add, which can either be tanked by a strong maintank or an offtank.
It is advisable to clear most of the adds in the room before engaging Herald of Solithex.
