Wyvern Rift

Inflicts Atk/Def-4 on foe during combat. If unit's Spd + Def ≥ foe's Spd + Def - 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 Def at start of combat - 35; min 0, max 7; "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 a foe or ally stats, treats unit's stats as if granted +X.
