Brid is one of the three Reindeer bosses in Droes Cave of Abyss.
Of the three deer, he is the easiest one to solo as he does not have an attack that can stun and he is melee. This does not mean that he is an easy kill. He has two skills, one is an aoe poison, so antidotes are handy and the other skill is a debuff that cuts base hp, defence, and mp by 50%.
