Oh boy. Your second elemental fiend. Now is it me, or does he look like some sort of tortoise on steroids? Anyway. This battle can be relatively easy or painfully hard, it depends on your equipment and what level you're at. His normal attacks take off triple digits, so get the potions and healing magic ready. Cagnazzo's major attack is his Wave attack. You'll see signs of it coming though, to prepare yourself, as there will be a message indicator saying "Tsunami Warning!". The water dissipates after the attack. Also, there will be times when he hides in his shell and cures himself. When he's in this state, do not attack him or else get an unpleasant counter attack.
Now, the strategy as far as your characters goes. Have Cecil attack with his sword, as usual. If a character desperately needs HP, have him use potions. Have Yang attack normally, or if you have the time, use Power for him to deliver a hefty attack. Twin magic takes a backseat to weakness in this battle. Have Porom be the healer and cast Cura every turn she comes up. Meanwhile, Palom smacks the fiend with Thundara, and Tellah uses that wealth of black magic to good use and crushes him with Thundaga. It will deplete his MP pretty quickly, in which case have Cecil or Yang give him an Ether. The name of the game is keeping HP up before he attacks with Wave, and keep Tellah's MP up so he can blast him with thunder. Cagnazzo should be laid to waste in no time.
