"I can carry the chest, if we want to take it with us.
If we have to fight, we should fight in the tight hallway, so we can take them on a couple at a time.
Spell-wise, Brawn has used 2 spells to heal himself today.
He has Endure Elements: Fire running from last night (he casts it every day before going to bed -"Fire hurts!"). He won't have it to cast tonight, since he converted it to healing.
He has a Shield of Faith left he would cast if entering battle.
If they must enter battle, Brawn's strategy is:
Try not to fight in open area, where all the little things can get at him at once.
Use Divine Might.
Use his Charm ability to increase personal power (CHA).
Use LaiC feat to keep the little guys back, AoO's and Cleave, too.
