Debuff is a gameplay element in Fire Emblem Heroes that reduces a character's stats under certain conditions.
Types of Debuffs
A debuff is caused by certain skills which can be divided into two types based on their activation criterias: Field Debuff and Combat Debuff.
Field Debuffs are visible stat changes highlighted in red. They are usually activated at start of a turn or after a unit's combat. These debuffs do not stack together, only the highest value will be applied to an affected stat. They do, however, stack with Field Buffs.
Unlike Field Debuffs, Combat Debuffs are not visible but they instead can be observed in the Combat forecast to evaluate the outcome of the battle. They are only activated during combat. These debuffs stack together with no upper limit, along with Field Debuffs and Field Buffs if any.
