Forza

Forza is a boss in Final Fantasy V. A hunter, he travels around with his wife Magissa, looking for things that will give a good bounty. He joins his wife mid-battle, giving the team more problems.

Strategy
Lenna should already have been cured of poison by now. When Forza appears, Magissa will focus less on attacking and more on healing Forza. As such, the party should just keep on attacking Magissa like it already was.

Once Magissa is out of the way, Forza shouldn't prove too difficult. His regular attack well deal some light damage, but his Tackle attack is another matter, taking off quite a lot of HP. As such, the best job to use is the Knight, and avoid the Monk class, which won't easily survive the attack. If you are using any Mages, have the Knight cover them if they're getting too low on HP.

A really quick way to defeat him is to break a Frost Rod, which can be bought in Carwen, instantly killing him and Magissa. A fun way to take care of Magissa is to confuse Forza, forcing him to attack Magissa until she is dead.
