An Envy Resonance E.G.O with an Unbreakable Coin that, on Clash Win, converts spare Envy resources into missing resources, with a passive that also inflicts Power Down on strong enemies.
Core Mechanics
Resource conversion: On Clash Win, spends Envy resources equal to Envy Resonance and gains the resources she has least of, 1 at a time (up to 4, 5 at Threadspin Ⅲ, 6 at Ⅳ).
On Clash Lose: Final Power drops by 4, but she gains Shield of Envy Resonance×5 (up to 20, 25 at Threadspin Ⅲ, 30 at Ⅳ). The conversion only works on a win, so use it when she can win.
Beware one-sided attacks: It has an Unbreakable Coin, and in one-sided attacks, the healing "on hit without being broken" does not trigger.
Debuffs and healing: Inflicts 2 Needles and 1 Nails on hit (plus 1 Curse from Threadspin Ⅲ). When it hits without being broken, heals the 2 allies with the lowest HP ratio by 6% of max HP (8% at Ⅲ, 10% at Ⅳ) (allies other than herself must have an Envy basic attack).
Passive — Loser's Penalty: Voodoo: Deals 4 Envy damage to the target on Clash Win. If her or the target's HP is below 33%, inflicts 1 Power Down next turn (once per turn).
How to Use
In teams that can keep Envy Resonance high, fire it in place of Skill 1 to trade Envy resources for other resources. It is good for securing resources that are hard to produce with Identity skills.
In teams that are not Envy-centered, it is likely an E.G.O used mostly for its passive.
It requires 1 Lust and 3 Envy, with an Awakening Sanity cost of 15. While in use, her Sin resistances switch to Fatal to Sloth and Gloom, Endured against Envy, and Normal for the rest.
The Corrosion skill is a single 3-Coin slot centered on multi-target attacks and debuffs based on Envy Resonance. See the skill section for details.

ANALYSISThreadspin
Ⅱ: Unlocks Loser's Penalty: Voodoo.
Ⅲ: Increases the conversion amount, healing, and Shield, and adds 1 Curse. Valuable if you use it often in Envy teams.
Ⅳ: Strengthens nearly the same items as Ⅲ further. If you can spare it.
