General strat: He randomly fears people, got a fear aoe and ports himself to two spots (one infront of the fear gate and one behind). When he ports everyone needs to stack ontop of him.
When adds pop burn em.
Have dirges and enchanters interrupt the fear every 25%
Tank him at the corner of the fear gate and have everyone have their back to the wall.
Someone needs to be sacrificed on the pull as he will death-touch you on the pull.
