“What the hell is wrong with you's! Are you's tryin' to steal our treasure!?”
—Barm's battle quote.
Barm (バーム Bāmu) is the thief boss who appears in the Archanea Saga chapter, Thieves' Gang of Justice. Barm is leading a group of thieves to steal as much as they can from the Dolhr-occupied palace of Archanea at the same time Rickard's group is robbing the place. In contrast to Rickard's comparatively more benevolent motives, it is implied Barm wants the treasure for selfish reasons.
Sword - C
Unlike other bosses, Barm is not that statistically strong and focuses on getting treasure unless someone is in his way.
As Barm will eventually get away if not stopped and his Armorslayer is the only effective way to defeat the Knights that litter the chapter, it is recommended to kill Barm as soon as possible. The most effective way is to use Lena to warp Nabarl to the entrance of treasure room, forcing Barm to attack Nabarl. On the next turn, use Nabarl to attack Barm again, finishing him off.
“M-my treasure... Damn... you's...”
- Though seemingly unconnected and harmful to Dolhr, their guards will entirely ignore Barm and his men stealing their treasure.
