Diablo basically gets two free shots on Dizzy, though.
Not really, no. It says refuses to fight until she's attacked. This doesn't mean "until damage is dealt", this means until she thinks she's under attack. Which will be pretty clear and considering her agility it wouldn't be surprising if Diablo didn't hit at all.
I could buy her trying to dodge until damage was dealt, but she certainly isn't attacking back until damage is dealt.
Does it say "damaged" or "attacked"? The wording is as it says, man.
If it's just "Attacked in a way that can miss," then that makes the ability useless, since anybody attacking the team at all would put Dizzy under the impression that she's "under attack."
I think it's been very clear that it's intended as "successfully attacked," and to argue otherwise is very dishonest.
EDIT: Actually, I think that even spells out the difference. The ability says "Attacked," not "under attack." That suggests that the attack has to succeed. In almost any RPG, somebody will be awaken from Sleep if they're "attacked," but the attack has to hit. A miss doesn't work. I definitely think it's like that.
Hmm. That's a fair point, actually. I'm still iffy on it (and do think that still Dizzy who gets tagged once > Diablo, but my Diablo respect isn't super high) but I see where you're coming from. ---
