Dusk Vigil Ashen Staff freeze problem.

Freezes when using the "Dusk Vigil Ashen Staff" staff, during the casting of any spell, the character begins to jerk violently as if he is being frozen. There is no such problem without this staff. I assume that the problem is in the autocast Amber Squall * level

It is extremely uncomfortable to play
