Momentum

Type	Name	SP	Required	Description
B	Momentum 1	60	—	If unit or foe initiates combat after moving to a different space, unit makes a guaranteed follow-up attack and deals damage during combat = number of spaces from start position to end position of whoever initiated combat (max 5; including when dealing damage with a Special triggered before combat).
	Momentum 2	120	Momentum 1	If unit or foe initiates combat after moving to a different space, unit makes a guaranteed follow-up attack and deals damage during combat = number of spaces from start position to end position of whoever initiated combat × 2 (max 10; including when dealing damage with a Special triggered before combat).
	Momentum 3	240	Momentum 2	If unit or foe initiates combat after moving to a different space, unit makes a guaranteed follow-up attack and deals damage during combat = number of spaces from start position to end position of whoever initiated combat × 3 (max 15; including when dealing damage with a Special triggered before combat).
	Momentum 4	300	Momentum 3	If unit or foe initiates combat after moving to a different space, inflicts Atk/Def-4 on foe, unit makes a guaranteed follow-up attack, and deals damage during combat = number of spaces from start position to end position of whoever initiated combat × 4 (max 20; including when dealing damage with a Special triggered before combat). If unit initiates combat after moving to a different space, triggers the following effects depending on unit's equipped Special: if unit has an area-of-effect Special equipped, grants Special cooldown count-X to unit before Special triggers before combat (excluding Røkkr area-of-effect Specials); if unit has a Special that triggers when unit attacks (excluding area-of-effect Specials), grants Special cooldown count-X to unit before unit's first attack during combat (if number of spaces from start position to end position ≥ 3, X = 2; otherwise, X = 1).

Notes[ | ]

The calculation of "spaces from start position to end position" counts the total number of spaces from the initiator's starting position to the end position before combat.
- The calculation includes spaces occupied by an ally with the 【Pathfinder】 effect.
- The start position used in the calculation references the initiator's starting position after being moved by sources of unit movement such as Reposition.
As a general rule, if a unit is both prevented from making, and guaranteed to make a follow-up attack, the effects cancel out, and the Spd difference decides instead (including effects that alter the Spd difference such as Frozen).
A foe with effects such as Phys. Null Follow or Null Follow-Up will neutralize the guaranteed follow-up attack granted by Momentum.

The damage boosting effect is a flat +X (max: 20) damage that ignores the foe's Def or Res when calculating the damage boost, and can be reduced by damage reduction effects such as Gust, Atk/Spd Excel, and Dodge.
- A foe equipped with Embla's Ward, Múspellflame, Niðavellir Axiom, or Gold Perfection will neutralize all sources of damage during combat except the minimum 1 damage from Umbra Burst weapons.
- For more information, see Damage calculation.
The stat decrease that can be applied by Momentum 4 is considered a temporary debuff.
Momentum 4's Special cooldown count increase that occurs during combat is a flat +1 and is not affected by effects related to Special cooldown charge such as Guard, Special Cooldown Charge +1, and Spd/Def Tempo 4.
- All flat cooldown count increases and/or reductions during combat will stack with each other if they trigger at the same time.
  - For example, if a unit with Special trigger acceleration has Rally Spectrum and Hush Spectrum, the effects will stack and the unit's cooldown count will not increase or decrease.
