Posting from my phone right now, so I can't answer your question at the moment, phae. However, I have a question of my own: considering my terrible AC, should I swap the wings for displacer beast hide as well?
Pro wings:
-high (and increasing) flight speed
-I plan to stay as far from combat as possible, and this will help me do that
-aesthetics / kinda fits the concept (but not like a glove)
-I already have DR and SR
-6/encounter I can sub a sense motive check for my AC against a single melee attack (immediate action)
Pro miss chance:
-my AC is terrible
-I can cast fly, if necessary
-my AC is TERRIBLE
