Final Fantasy Tactics Walkthrough

Steal the Chemist's Glacial Gun in this battle! Depending on when you start this quest, it might be your first chance at a magical gun, like Mustadio described in a cutscene just after meeting him. If that Chemist is the last enemy left, you may have to kill Beowulf so he doesn't end the battle first, but you definitely want this gun as spell guns are few and far between.

This battle is pretty simple, just take out the monsters first when they get close, as they are the most powerful, then Thief 1 and Thief 2, and the Chemist once you've gotten his gun away from him. Having more than one person capable of stealing is handy so you can gang up on the Chemist and more quickly get the weapon.

Again, Holy works nicely, and having someone to heal is a definite must, due to the threat of the monsters and their powerful physicals.
