Final Fantasy Tactics A2: Grimoire of the Rift/A Paw Full of Feathers

First off, avoid using any kind of fire-based attack in this mission. You will be against two Wolves and a Baknamy in this battle. Attack the Wolves one at a time, having everyone attack (one round of everyone attacking should kill a Wolf). Once they are done, go after the Baknamy, which has slightly stronger attacks and more health. If any of your units gets ganged up on, heal up with a White Mage or by using items.
