I was a AF II The beginning user once upon and decided to get to Arena, but during the duels when i use a spell there occurs a big lag and then the game crushes and i also have some of the crushes that has given under this topic but i am still satisfied with the game

I also have repeated crashes during duel. I can play through two duels and then the game crashes.
