Black Eagle Rule | 300 | — | If unit's HP ≥ 25%, unit makes a guaranteed follow-up attack, and also, if foe initiates combat, reduces damage from foe's follow-up attack by 80% ("follow-up attack" normally means only the second strike; for effects that grant "unit attacks twice," it means the third and fourth strikes). |
| This skill can only be equipped by its original unit. | |||||

Notes[ | ]
- 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 Black Eagle Rule.
- "If foe initiates combat" means if a foe triggers combat during the enemy phase. The unit being initiated upon does not need to deal damage, nor be able to counterattack.
- However, if the effect is applied after combat, the unit being initiated upon must also survive it to fulfill this condition.
- The damage-reduction effect is calculated after offensive Specials and damage boosting effects such as Arcane Lúin and Dominance.
- If a skill such as Miracle or Everliving Domain can trigger, the damage-reduction effect will not trigger and the user will still survive with only 1 HP.
- "Reduces damage by X%" effects stack multiplicatively, unlike interactions related to the weapon-triangle, such as Triangle Adept and the weapon-triangle advantage boost.
- Non-Special "reduces damage by X%" effects can be neutralized or reduced by effects such as Share Spoils or Halves non-Special damage reduction.
