Amdapor Keep Psycheflayer glitch

People are using the glitch to have their ranged classes completely avoid damage and to not deal with the additional monsters during the second phase of the Psycheflayer battle.

A tree on the right has a branch that's climbable. Some groups have people jump onto it and from there just let the healer get hate from the normal cures so that everything sans the boss targets them. But then the adds can't hit the healer, so they just walk and target the wall. The height difference also prevents AOE damage on the healer and/or BLM.
