Comes with two adds an enamored fae drake which charm the group and especially tank. It's a good idea to kill these first. Unicorn will also spawn a monarch avenger to assist her, she just respawns them if they are killed so you just have to tank them all. As with other mobs in EH, this one also drains mana so you will need a strong tank and lots of dps. Mana regen is also necessary. Original two adds have around 660,000 HP and monarchs have 3,400,000 (possibly less depending how many will be spawned). This is a fairly long fight since most of the time group will be charmed or stiffled.
