About DEF Down

reduces DEF of a foe it's applied on, effectively increasing damage dealt by your party.
- A foe's DEF can be lowered by 50% at most. DEF Down debuffs can stack higher than 50%, but it will not exceed the 50% DEF Down cap.
DEF UpDEF is boosted
and DEF DownDEF is lowered
effects are additive. For example, if a foe has 30% DEF UpDEF is boosted
Strength: 30%, a total of at least 80% DEF Down debuffs are needed to hit the 50% DEF Down cap.- Stronger effects will overwrite weaker ones and weaker effects will show "NO EFFECT". Equally strong effect will override the duration (not extend it).
- Different sides of DEF Down stack additively with each other. Multiple effects of the same side can't be applied at the same time.
- Example:
Jeanne d'Arc (Dark)'s

20% DEF DownDEF is lowered
Strength: 20%Duration: 180 seconds. (20%, summon call side) gives a total of 75% DEF Down, but it'll be capped down to a 50% effect. - Damage Cut effects are not part of the DEF Up / DEF Down formula and thus are not part of the 50% cap.
- Example:
- DEF Down effects applied to characters do not function the same way they do on foes. Self-inflicted DEF Down effects cap at 99%.[1]
- Certain effects can surpass the cap by 10% due to their unique mechanics. Such effects will not stack with each other and only one will apply.
DEF Down Sides
DEF DownDEF is lowered
is the most common type of the DEF Down effect. Within this type there are four different sides that can be told apart based on their sources:- Character skills (including the Main Character's) can be either single-sided or dual-sided*.
- Character charge attacks and summon call effects are the other two stacking sides.
- DEF Down from a weapon's charge attack can be either one of above-mentioned two sides.
DEF DownDEF is lowered
Local status effect Local DEF Down only affects the party that cast it. Debuffs from the same source will override other effects based on strength, regardless of duration.- Turn-based effects such as
DEF DownDEF is lowered
Local status effect will end after a certain number of turns has passed. - Permanent effects such as
Shiva's
Purifying FlameHP is lowered on every turn / ATK is lowered / DEF is lowered (Can't be removed)
or Andira's
IwazaruDEF is lowered (Effect increases upon each Multi-Decree cast [Max: 3 times] / Can't be removed)
Local status effect won't expire regardless how many turns or time has passed.
- Turn-based effects such as
- Elemental DEF Down
Fire DEF DownDEF is lowered for fire DMG
Water DEF DownDEF is lowered for water DMG
Earth DEF DownDEF is lowered for earth DMG
Wind DEF DownDEF is lowered for wind DMG
Light DEF DownDEF is lowered for light DMG
Dark DEF DownDEF is lowered for dark DMG
only reduces Defense for attacks of the same element as the effect. Only the strongest effects will apply, regardless of source.- Example:
Water DEF DownDEF is lowered for water DMG
won't lower foe's Defense against Wind attacks. - Example:
Water DEF DownDEF is lowered for water DMG

- Example:
DEF Down (Stackable)DEF is lowered (Stackable)
will apply one stack of the effect, up to a certain cap (the strength and cap of the debuff differs by source).
If two or more effects from different sources are applied, they'll add to each other, up until the cap of the corresponding skill. If the cap is already reached, only the debuff duration is refreshed.[2][3]- Example:
Athena's Tetradrachm5-hit, 100% Fire damage to random foes (Damage cap: ~120,000 per hit).
Inflict 10% DEF Down (Stackable / Max: 40%)DEF is lowered (Stackable)

Water DEF Down (Stackable)DEF is lowered for water DMG (Stackable)
Earth DEF Down (Stackable)DEF is lowered for earth DMG (Stackable)
Wind DEF Down (Stackable)DEF is lowered for wind DMG (Stackable)
Light DEF Down (Stackable)DEF is lowered for light DMG (Stackable)
Dark DEF Down (Stackable)DEF is lowered for dark DMG (Stackable)
's mechanics are a combination of Stackable DEF Down and Elemental DEF Down: it applies up to a certain cap, and lowers DEF only for one element at a time.
* Single-sided and dual-sided are community-made terms made for easier debuff classification. There is no in-game text differentiation.
