Cutter's Cry is fun as a healer because it is more than just being a healing bot when you are lower level.

First boss: The healer kiting is usual practice and don't expect to easily be able to throw heals. The strategy here is for the tank and DPS to burn the boss quickly. I usually toss instant heals whenever I can and use Sprint whenever its up.

Second boss: Anytime you see the sandworm go underground, quickly run to the edge of the room. I try to stay near the other players whether possible whenever I run to the edge so they are not out of range from my heals.

Third boss: The boss will occasionally change eye colors that denotes an impending AOE attack. This fight is easy IF everybody pays attention... unfortunately, you will get a player or two that doesn't. Violet = get on top of the boss to avoid a room wide AOE; blue = run far away to avoid a close range AOE. Also, you will occasionally get targeted by a blue orb in which you need to run away until it explodes.
