Bo-Boys

Bobo Boys have a missile attack, they kill other enemies far more often than other monsters do. The higher the highest level of the Bobo, I think that's the cranky old man tank or something like that. They get two actions a year action. Their cannonballs do flash damage. Even then every time they kill a monster, even though they don't level up, they still get healed. If you're on every on a level, one of those run yeah.
