Fire Boost (Japanese: 生命の業火 Hellfire of Life) is a three-tiered passive type A skill which debuted in Fire Emblem Heroes; the individual tiers of the skill are Fire Boost 1, Fire Boost 2, and Fire Boost 3 in order from lowest to highest. When its user has sufficiently more HP than their foe, Fire Boost boosts their attack; the size of the boost increases with the skill's tier.
