A multi-target Pierce E.G.O (7 Attack Weight at Threadspin Ⅳ) that hands out Rupture, Bleed, and Gluttony Fragility together, with Pierce buffs and Bind that make later fighting easier.
Core Mechanics
Multi-target spreading: 5 Attack Weight (7 at Threadspin Ⅳ); Coin Ⅰ inflicts 2 Rupture on hit and 2 Bleed on Heads Hit.
Gluttony Fragility: From Threadspin Ⅲ, inflicts 2 Gluttony Fragility on hit. It meshes with Rupture teams that have many Gluttony skills.
Passive — Stem of Distrust: Gains 1 Pierce DMG Up every turn. On Heads Hit, inflicts 1 Bind next turn and Rupture Count increases by 1.
Stable power: Power 19–26 (22–29 at Threadspin Ⅲ) with a high minimum, making it easy to win even at low SP.
How to Use
Its Gluttony and Pride costs are heavy (2 Lust, 3 Gluttony, 1 Gloom, 4 Pride), so build the team assuming one of those is covered by teammates.
Fire it when there are many enemies, and use Bind to create a Speed difference next turn so Rupture Identities that use Speed difference can act more easily.
Sanity cost is 20 for both Awakening and Corrosion. The Corrosion skill is an enhanced version with higher power (5 Rupture, 5 Bleed, and 3 Gluttony Fragility on hit at Threadspin Ⅲ).

ANALYSISThreadspin
Ⅱ: Unlocks Stem of Distrust.
Ⅲ: Base Power rises by 3, and Gluttony Fragility infliction is added.
Ⅳ: Attack Weight becomes 7. Its damage likely falls behind other 7-Attack-Weight E.G.O, so it serves to add options.
