Type(s) Passive (Type A) First game Heroes

Triangle Adept (Japanese: 相性激化 Compatibility Intensification) is a three-tiered passive type A skill which debuted in Fire Emblem Heroes; the individual tiers of the skill are Triangle Adept 1, Triangle Adept 2, and Triangle Adept 3 in order from lowest to highest. Triangle Adept boosts its user's attack if they have the advantage in the weapon triangle, but penalizes them if they have disadvantage; the bonus increases with the skill's tier.

Triangle Adept entered the main series in Engage, where it instead guarantees follow-up attacks based on who has weapon triangle advantage.
