  • Kefka takes half damage from all magic and has a 50% evasion to all physical skills. Kefka will not be hit by any unfocussed spells (Quake, Meltdown, Tornado) that he casts, but is still susceptible to any the party uses.
  • Kefka will now have an irremovable status effects of Haste/Protect/Shell
  • Kefka will counter any physical hit with Havoc Wing
  • Kefka will replace Havoc Wing with Hyperdrive in his normal repertoire of attacks.
  • Kefka will now triple cast Flare, Holy, and Meteor. He will single cast Ultima.
  • Kefka can now also use Curaga which will restore 9999hp, if Kefka's HP somehow returns to Phase One status, Kefka will enact the Barrier Change tactic again but still retain all of his abilities from Phase 3.
  • Kefka will still charge up and use Forsaken though its casting time is faster.
  • When HP is reduced to zero, Kefka will use the attack Light of Judgement as a final attack. LoJ will be just a recolored version of Forsaken, Kefka will also use his trademark laugh as he disintegrates.
Sounds overpowered in case you don't deal ridiculously high damage like it is normal in Final Fantasy VI.

I would just make him immune to (damage) magic during the whole battle. And yes, I would give him Light of Judgment.
