Big Monkey summoning ritual!

The boss big monkey, when summoned in a ritual, begins swinging his huge stone at the moment of his appearance. Because of this, it is extremely difficult to react, please correct this point, in a bunch of monsters and summoning additional bosses, it is an extremely difficult task to overcome. The difficulty is with the window for maneuvering when summoning the big monkey, I did not notice any difficulty with the rest of the bosses.

wrong game sry!
