Well I Found Thats Slow,Blink,Reflect and Dispel Help Alot Against Bosses
Examples:When you are Fighting The Dark Elf if you put reflect on tellah and cecil it really evens the playing field .When it Transforms Into the Dragon Cast Blink on the charcters and you wont be hit.Slow is Good Against Any Boss.Dispel is good because it takes away magical effects such as "The Sap Status" That is left After an oppenet uses Bio.Well I Hope This Helped.
