the 3 slam strike is absolutely broken good luck dodging it and if you do itll still hit you. horrible boss design and horrible placement and level design.

It has a random three cone strike that blasts whole length of room 30 degree in front of him and he turns to the target so you need to be in an open area and constantly run.
