The Brothers attack is earth-based, and that makes for great damage to those touching the ground. But if the enemy is airborne, or has immunity to earth, avoid using them in a fight.
Simply the best two abilities for Brothers is the HP+80%, and HP Bonus. If you can get them early enough in the game, you have a great chance for getting a character in the higher HP range. If you are the Paladin type, Cover gives you the ability to defend your allies. This is good, if they are within a shot of being KO'ed.
