Master Assassin is a mob affiliated with the Rooks. They utilize a directiona AoE attack originating from themselves. They are a fearsome adversary when unprepared.

There were two Master Assassins that worked under Bael, the leader of the Rooks. They were defeated, along with their master, at the Rooks' Nest.

How to defeat them

After Bael is killed, the Master Assassins he summoned do not have to be defeated. It is recommended that the player simply utilizes the portal to Kraag.

If, however, one wishes to defeat them, a rogue character would have the best chance, allowing the player to circle and avoid attacks while dishing out high damage.
