Inflicts Atk/Spd-4 on foe during combat. If unit's
Spd + Res ≥ foe's Spd + Res - 10 (excluding
effects from【Phantom】), unit deals +X damage
(excluding when dealing damage with an
area-of-effect Special) and reduces damage
from foe's first attack by X during combat
(X = unit's Res at start of combat - 30; min 0,
max 10; "first attack" normally means only the
first strike; for effects that grant "unit attacks
twice," it means the first and second strikes),
unit makes a guaranteed follow-up attack,
foe cannot make a follow-up attack, and
increases the Spd difference necessary
for foe to make a follow-up attack by 20
during combat (Spd must be ≥ 25 to
make a follow-up attack; stacks with
similar skills).

【Phantom】
If a skill effect compares unit's stats to foe or
ally stats, treats unit's stats as if granted +X.
