Battle 1. Keep everyone alive. Equip Anti-Poison and Absorb Fire on everyone for added advantage.
Battle 2. Kill the dog using Poison rings, as this is the only way to take him down. You should achieve Perfects with your hits or the skill master will do more damage. Equip Persistence on Kaim for added advantage. He can be tough, so save first since you might have to try again.
Battle 3. Hit the Moneys with fire spells or Fire-based melee attacks (or All-Flare spells). They only do coin tosses if they're hit with fire based spells or attacks, and they do not do it all the time too. You have to acquire 10 favorable coin tosses within 10 turns, and you need to defeat them within that period too. Patience and luck is required.
Battle 4. Cast Gamble on the Silver Kelolon.
Battle 2 is actually considered the hardest out of this class.
Make 2 Greed rings and 1 Master Ring. They arent hard to make. The master ring & greed rings are combo rings, so go to the white boa and check out the ring maker for the requirements.
Equip a Toxin lv 3 ring on Seth, and Greed ring on kaim. have persistance and Crisis defense (not to be confused with the other crisis defense. Equip the one that gives complete defense). Attack the guard with Kaim in the first round, and Attack the dog with Seth as well in the first round. Make sure you land a perfect with seth on the dog. Since she is the fastest, shell go first anyway. The dog will get poisoned, and in 4 turns hell croak. Try to get as much damage on the guard in these 4 turns. But make sure you follow his ring rules, hell say hit good bad or perfect. After the dog dies hell start casting coverus and shieldus on himself, but dont worry. Swap out seths Master ring for the spare Greed Ring. Attack the guard with Kaim and Seth, and defend with your other 3 characters. Land Perfects and hell be dead in no time!
