Bitoso has a tendency to cast Cure III on himself. This makes it difficult to kill him, since he recovers so much HP while you're trying to wear him down. Most of the strategies involve interrupting him or preventing him from casting. Edit Jan 06, 2008: This "Tip" is highly misleading; Bitoso practically spams Cure III (even when over 90% HP). Even during prolonged fights (5+ min) Bitoso did not run out of MP.
