Also, even without feats, Xykon has more than enough wealth to get Wish from a scroll.

As to V, the only thing V has done which actually HINDERED the OOTS was kill the draketooths. That's it. Everything else zimmerwald1915 keeps saying makes V a 'liability' is V being of minimal help. In order for V to be "more a liability than an asset", then killing the draketooths would need to have caused more harm than everything else V has ever done. Including preventing multiple TPKs (yes, including the adult black dragon), the stuff in the battle for Azure city, killing a CR 20 devil that probably would have TPKed the order AND possibly Hinjo...
yea, sorry, I'm not seeing it.
