GUIDEMechanics and How to Use

At a Glance

A Pride E.G.O with 7 Attack Weight that sacrifices an ally with its first Coin so the second Coin can hit multiple enemies.

Core Mechanics

First Coin: shooting an ally: Prioritizes the target with the lowest HP, favoring allies. Coin Ⅰ only hits the main target. Against an ally, gains +8% damage per Torn Memory, increased to +10% at Threadspin Ⅲ and +15% at Ⅳ.
Second Coin: spreading to enemies: Coin Ⅱ only hits subtargets. If Coin Ⅰ fails to kill an ally, only 1 random subtarget takes damage.
Torn Memory and Poise: Before attacking, gains Torn Memory equal to the highest Resonance + 1, up to 7, then gains 1 Poise per Memory. At Threadspin Ⅳ, Pride Resonance instead gives Memory equal to twice the highest Resonance. Consumes all Memory after attacking.
Killing an ally: Grants 2 Poise to himself and 2 allies, increased to 3 at Threadspin Ⅲ. From Threadspin Ⅲ, also gains resources matching the defeated ally's S1 affinity; Threadspin Ⅳ adds their S2 affinity. If he fails to kill an ally, gains 1 Poise himself, increased to 3 at Threadspin Ⅲ.
Passive — Next: Active from the turn after E.G.O use. After attacking, if a target died, gains 2 Poise Count, up to 2 times per turn.

How to Use

The lowest-HP ally is prioritized as the sacrifice. Prepare an ally he can finish off, such as one who is near death, Staggered, or naturally low in HP. Since it prioritizes allies, this is a poor choice for Clashing with enemies.
From Threadspin Ⅲ, killing an ally generates resources, reducing the effective cost.
Higher Resonance generates more Torn Memory and raises the damage bonus. At Threadspin Ⅳ, Pride Resonance doubles the Resonance contribution.
Costs 2 Wrath and 6 Pride. SP cost: 25 Awakening, 30 Corrosion, 45 Overclock.
Corrosion cannot distinguish friend from foe and has a larger damage bonus against allies.

ANALYSISThreadspin

Ⅱ: Only unlocks Next.
Ⅲ: Raises the Memory-based damage bonus and Critical damage cap, and adds resource gains when an ally is killed.
Ⅳ: Further raises damage bonuses and the Critical damage cap, and adds resources matching the ally's S2 affinity. These are substantial improvements, making this a relatively high-priority upgrade if using the E.G.O.
