Bonus Doubler (Japanese: 強化増幅 Enhancement Amp) is a three-tiered passive type A skill which debuted in Fire Emblem Heroes; the individual tiers of the skill are known as Bonus Doubler 1, Bonus Doubler 2, and Bonus Doubler 3 in order from lowest to highest. Units with a Bonus Doubler skill multiply any bonuses currently in place on it whenever they're in combat; the multiplication factor increases with the skill's tier, with the skill's name only being truly indicitave at the third tier as the multiplier does not double the bonuses in the first two tiers.
