Rastakhan's Rumble Guide
Vowing vengeance, his cursed crew haunts Gilnean shores.
Not really that great of a fight. When one of the main ways to beat a boss is to hope that they play a Fel Reaver then mill them, that's not good design. Your deck choices leading up to this boss mean little in that case.
My reaction when this guy drops Fel Reaver after spending most of the fight kicking my ass:
Easy win if you have any vitality buffs. Just wait for him to drop Soul Reaver and then just mill him as the Soul Reaver will always go face.
