A Gloom Sinking E.G.O that stacks heavy Sinking with a multi-target Blunt attack, with a passive that also spreads Bind and Attack Power Down.
Core Mechanics
Inflicting Sinking: Sinking Count increases by 2 on hit (3 at Threadspin Ⅲ, 5 at Ⅳ), and at Threadspin Ⅳ it also inflicts 5 Sinking. As a multi-target attack with 3 Attack Weight, it can stack Sinking on several enemies.
More damage at 50%+ HP: +10% damage (+30% at Threadspin Ⅲ) when the target has 50% or more HP.
Tremor Burst: On hit, shifts the target's Stagger Threshold by its Tremor Potency (only on Heads Hit at Threadspin Ⅱ or below).
Passive — Coldness: Hitting an enemy with at least 5 Sinking inflicts Bind and 1 Attack Power Down next turn (up to 3 per enemy).
Corrosion skill: Targets the highest-HP target. At Threadspin Ⅳ, Attack Weight becomes 3 and Sinking increases, but it catches allies.
How to Use
Use it in a Sinking team, firing it once Coldness's condition (5 or more Sinking) is met. At Threadspin Ⅳ, its own Sinking infliction likely makes the condition easy to create.
Fire it early while enemy HP is high to get the damage increase.
It requires a heavy 5 Gloom and 3 Envy, with a Sanity cost of 20.

ANALYSISThreadspin
Ⅱ: Unlocks Coldness.
Ⅲ: Base Power 13→15, 30% damage increase, and the Sinking Count increase becomes 3.
Ⅳ: Sinking infliction is greatly strengthened. Corrosion becomes multi-target and catches allies, so in builds where SP tends to drop, stopping at Ⅲ is likely a reasonable choice.
