A single-target Envy Pierce E.G.O used before allies attack to inflict Pierce Fragility and Envy Fragility, raising the damage of the Pierce and Envy skills that follow.
Core Mechanics
Inflicting Fragility: On hit, inflicts Pierce Fragility (3 at Threadspin Ⅲ) and 1 Envy Fragility. Fragility only lasts for 1 turn, so it must land before allies attack.
Curse (Threadspin Ⅲ): Inflicts 3 Curse on Heads Hit. At Turn End, it applies one random effect such as Attack Power Down for the next turn, so you cannot choose the result.
Nails and extra damage (Threadspin Ⅳ): Inflicts 3 Nails (a special Bleed) on Heads Hit and deals +50% damage to targets with Curse.
High Clash Power: A fairly high 14–24, or 16–26 at Threadspin Ⅲ. If the team can cover 6 Envy, it also works for Clashing.
Passive — It Hurts!: +10% damage dealt for each negative effect on herself, up to 50%.
How to Use
Fire it first with a fast Identity, apply Fragility, and then let allies attack.
Use Awakening if the follow-up attackers mainly use Pierce, and Corrosion if they mainly use Envy. Corrosion inflicts 1 Pierce Fragility and 1 Envy Fragility, or 3 Envy Fragility at Threadspin Ⅲ. Corrosion cannot distinguish friend from foe, and its targets are random, so it can hit allies.
It only requires 6 Envy, so pair it with a team that can produce plenty of Envy.

SYNERGYTeams and Synergies
The One Who Grips: Her Envy S1 supplies resources, and S1, S2, and S3 all inflict Nails, which fits the Threadspin Ⅳ Nails.
W Corp. L2 Cleanup Agent: Her S1 and Defense skill are Envy, making the 6 Envy easy to gather, and her passive also triggers with Envy Owned.
For 1 turn, damage taken from skills increases in proportion to this value (maximum 10).
Curse
At Turn End, gain 1 random effect among 1 Power Down, 1 Defense Power Down, 2 Offense Level Down, and 2 Defense Level Down, and this value decreases by 1.
Nails
Special Bleed
At Turn Start, inflict 1 Bleed and increase Bleed Count by this value.
At Turn End, this value is halved. (Rounded down)
