Hello,

When boss in dungeon doing a devastating attack and I need to use defensive skill (see picture link), if I do this to survive my game freeze for 5 secondes to 1min-2min, so finally I'm dead... If i click some times on the game, game crash.

Have you a solution to resolve this problem ? Disable this, or disable the animation and keep feature.

 

It's really a problem to clear dungeon...

 

Thank you for your help.
