Halloween Bomb is a skill that appears exclusively in Dragon Quest Tact. It is one of Halloween Dora-in-Grey's signature abilities, bombarding a group of enemies with an explosion of dark energy that can restore some of her HP.
Halloween Bomb can be learned by Halloween Dora-in-Grey at level 52 and costs 100 MP to use. It inflicts major Zam-type martial damage to all enemies in a plus sign-shaped area of effect and heals her by 20% of the damage dealt. Upgrading the skill increases its damage and reduces the amount of MP it costs to use.
