A Pierce E.G.O for Sinking teams, with an Awakening that consumes Sinking to restore SP and a Corrosion skill that pushes in Gloom Fragility.
Core Mechanics
SP recovery: After the attack, restores 10 SP to himself and the 2 allies with the lowest SP (12 at Threadspin Ⅲ, 15 at Ⅳ).
Bonus from consuming Sinking: If the target survives, it spends 5 of the target's Sinking Count (3 at Threadspin Ⅳ) and adds healing equal to the target's Sinking Potency (total capped at 20).
Spread on kills: If the target dies, inflicts 3 Sinking on 2 random enemies (3 at Threadspin Ⅳ). From Threadspin Ⅲ, it also adds 1 Curse.
Passive — If I Could Go Back...: If the target is dead at the end of the attack, he gains 1 of the E.G.O resource he has least of. +1 more per 5 combined Sinking Potency and Count on the target (up to 3).
Corrosion skill: An offense-leaning skill that inflicts Gloom Fragility, Sinking Count, and Curse. At Threadspin Ⅳ, damage against Cursed targets becomes +50%.
How to Use
Fire it at enemies with plenty of Sinking to restore SP. It reduces Sinking, so choose when to use it. Awakening is supplementary, and running it around the Corrosion skill that pushes in Gloom Fragility is likely also an option (Corrosion cannot distinguish friend from foe and can hit allies).
Firing it when it can defeat an enemy also replenishes resources.
It requires 2 Lust and 4 Gloom.
