Am I the only one who thinks that maybe 6 quatum for it to only affect your enemy might be a bit much for being upgraded? Maybe like 5. And I also agree that air seems like a better choice for it. Good idea
well, when the enemies sleep and you don't, spell gives you a serious advantage, that's why i gave it 6
.. and in frozen spell, creatures don't attack the same turn they defrost, same thing is gonna work here.. they're gonna attack the next turn they wake up.. and at least 1 turn is a good benefit .
