if you attack ozma phsyically it will miss unless youve given all the freindly monster what they want(if you find a gimme cat run away.if you give him the item he legs it and gives u nuthin and if you attack him he counters with powerful attacks.)after you give the last gemstone to the last freindly monster it will say "yay! now you can reach the round guy"which means you can attack ozma physically so if you have powerful attack you will do 9999 D per turn.
