I kind of like the idea of Normalize being able to affect immaterial creatures. Like an anti-Quintessence. That would be cool.
Okay, it can affect Immaterial creatures. It can't target them, though. Happy now?
Also, we suggested this already. I did, I mean. Months ago.
Immaterial: Untargetable
Immortal: Doesn't die when HP=0 and unaffected by killing effects
