Passives

"Types of Passive Skills: There are three types of passive skills: Misc. A, Misc. B, and Misc. C. These skills take effect after you equip them. You can equip one skill for each type."

Just like their names state, passive skills are skills that, under certain circumstances, apply various effects affecting gameplay. Passives in Fire Emblem Heroes are divided into 3 categories, A, B and C. Although not official, skill types roughly determine the general effect of the skill.


 * Type A - Affect only the character, either by adding additional effects or characteristics to the unit, or simply by buffing the character's stats.
 * Type B - Battle related skills. These skills change the dynamic of the game during or after combat. This category has varied effects.
 * Type C - Can affect your allies or enemies. The buffs or debuffs applied to the battlefield, although not directly affecting combat.

Skill Interaction provides an overview of passive skills that may interact or overlap with other passive skills and weapons.

Some passive skills are available as Sacred Seals, and some Sacred Seals can have skills not available as passive skills on any unit (listed here).

All those skills either automatically come with the character or must be learned, like every other skills, at the cost of SP. Every character has one slot for each type, and the user cannot equip more than one passive skill in each slot. Passive skills can be, however, unequipped if the user feels it has a negative impact on the unit's performance.
