Negative mana effect

Can someone tell me what all of the negative mana effects are in the game? Also, does Alfrikes Mindless Attack count as a negative mana effect? I’m trying to figure out what the clerics superior talent will reflect.

Yes Clerics can resist Mindless attack. S1 Clerics can even throw it back at Alfrike.

Any Status effect that affect mana negatively like mana slow or Mana Stop as well as effects that prevent using heroes special abilities, like Silence or Mindless attack can be resisted.

I haven’t seen it being reflected, but Clerics can resist Lepiota’s special skill that send them into Ghost form.
