The Evil Eye

It's the Bonelords' Boss. It can cause Death Damage and all different kinds of Magical Damage. Always spawns with 5 Bonelords and 3 Elder Bonelords near it. When The Evil Eye is present in Hellgate, large clusters of Bonelords and Elder Bonelords (groups of 5 or 6) that are not normally present appear.

The Evil Eye attacks from a distance. The Evil Eye never retreats.

Knights should rush in and kill it fast if you have no shooters. It has no Melee attack, so it will continue to use its distance attacks when you are up close. Be especially careful of the many Summons, and use Berserk to kill them if necessary. Using a Stealth Ring may be useful to avoid the Demon Skeletons' extra damage.
Paladins Stay diagonal, hit them with your weapon, and exori san. Use potions if your health is low.
Mages should use their wand to kill him. Avoid or ignore the summons and kill The Evil Eye first unless you are taking too much damage. It might be useful to run in circles to avoid getting hurt by the summoned Demon Skeletons and Ghosts. Also, using Invisible or a Stealth Ring might be useful to avoid the summons' damage.
