Crash when casting on iPad 2

I had problems with the tutorial not working but I finally got past it but I’m on an iPad 2 and the casting in battles always crashes my game. I’m in depth 2 and I’ve restarted and wiped my iPad 2 of memory quite a few times now and whenever I cast it’s an instant crash. Please fix

I am encountering the same crash, same system.

iPad 2 has 512 MB RAM and this game requires 1 GB.
