Irahsae

It's wearing a large Cobra Crown.
One of its speeches, scientia potentia est, is a Latin phrase meaning "knowledge is power".All players who sufficiently damage it during the last minute of the fight will receive the Slayer of Irahsae achievement.

Fights at close combat, runs away at very low hp. Does not retarget from the blocker, even when taking massive damage from the shooters.

Similar to a Fury, but weaker. A 4 person team is enough to safely bring down this monster. With a blocker, and 3 shooters, you should be fine. Irahsae will stand in close combat to the blocker at all times until it is very close to its death. If possible, get at least 2 Master Sorcerer's who can shoot Sudden Death Runes, because of the massive death damage this creature takes. A royal paladin or an elder druid would come in handy, to either inflict damage, or heal the blocker with Heal Friend. Irahsae is not too strong, but the blocker could take considerably high combos of up to 700 damage, maybe more. An Elite Knight of level 55 and higher with good skills and a good set should be able to survive blocking this monster us Strong Health Potions. Amount of waste will depend on how fast the shooters can bring it down. Once it starts to run, make sure all mages shoot Sudden Death at Irahsae before it hides and heal.
