Magissa

Magissa is a boss in Final Fantasy V. A hunter, she travels around with her husband Forza, looking for things that will give a good bounty. Seeing Princess Lenna, she attacks, hoping to take the Princess in.

Strategy
The battle will begin with a poisened Lenna, so you should take care of that to begin with. A White Mage should start off by casting Poisona on Lenna, and then continue healing the party for the rest of the battle. Magissa isn't really weak or resistant to anything, so you should concentrate on attacking her. Her Aero spell does some moderate damage to its target though, so be careful. If you have a Blue Mage with you, they can learn Aero now, but you should have learned it much earlier.

After a while, she will summon Forza. Now Forza will concentrate on really hurting your team, while Magissa heals him. Don't focus on Forza until Magissa is gone. She'll still attack from time to time, but will focus more on her husband.

A really quick way to defeat her is to break a Frost Rod, which can be bought in Carwen, instantly killing her and Forza.
