Adel (boss)

In this battle, Adel has Rinoa chained to her. Rinoa also has HP, but not much of it, so if she dies, it's Game Over. Cast Regen on her at the start of the battle, followed by Shell, and be sure to Regen and Shell all of your characters as well (Quistis' Mighty Guard works wonders). Adel will frequently drain HP from Rinoa, so make sure one of the fighters has the Recover command to top her up occasionally.

Adel uses a host of powerful spells, but as she's been cryogenically frozen for the last seventeen years, she's a bit rusty at actually casting them. She will drain HP from Rinoa, then blast you with a Flare, Holy, or something similar. Her Energy Bomber skill is a physical attack against your whole party, but does little damage, so don't worry about it overmuch. When you see "Magical powers are concentrated on Adel!" be prepared; her next spell will be Ultima. This spell can do up to 3000 damage, but if you have high Spirit and Shell status, you should survive it with ease.

All multiple-target attacks are out. Ignore Ultima, any GFs (except Cerberus,) and most Limit Breaks. Have Squall, Irvine, and/ or Selphie serve as the healers of this battle, topping up Rinoa's health and protection. Put Aura on Zell and/ or Quistis: for Zell's Limit Break, do not activate any of the finishing moves; for Quistis', use Homing Laser, Gatling Gun, Laser Eye, or Acid.

You should find Adel to be relatively easy if Rinoa remains safe through the battle.
