As for this fight, don't know much about Etrigan, but Nova has been busted up pretty badly by guys that use magic to physically amp. Back in his rookie days the Sphinx beat the living shyte out of him with amped magic, most recently Lord Mar-vell did the same using some kind of magic energy. On the flip side he has taken blows from mjolnir/Thor, Glads, Namor, Korg etc with no ill effects and has resisted magical possession, probing, spells etc.
So if this guy Etrigan uses magic to amp physically or whatever, then history shows that Dick could be in trouble here. Just my 2 cents.
