Very good feedback.
One thing i think i got correctly:
I think that ice spells actually give a certain resistance to damaging those enemies, based on the logic of being practically like a kind of armor, to those that you freeze completely.
Then you are hitting all that ice you created too, not just enemies. If youre using ordinary weapons for it... hm, should try using other elemental spells on those, see what that does.
I found that really cheeky, in a way, completely fitting the game - and great fun

- i really hope it isnt just a bug.
