GUIDEMechanics and How to Use

At a Glance

A multi-target Wrath Slash attacker E.G.O that reuses its third Coin while cutting into its own HP, spreading Burn and Bleed and handing Rhythm to allies.

Core Mechanics

Coin reuse: When the third Coin lands Heads, if his HP is 10% or more, he takes 4–8 self-damage and reuses the Coin (up to 4 times per skill; no Stagger or death). Each reuse adds 1 Burn and 1 Bleed.
Bonuses from Bleed and Burn: +1 Clash Power per 2 combined Bleed and Burn on the main target (up to 6, 8 at Threadspin Ⅲ, 10 at Ⅳ). Damage also increases with the ratio of HP lost (up to 10%, 15% at Ⅲ, 20% at Ⅳ). Damage to sub-targets is −50%.
Distributing Rhythm and SP: On hit, gives Rhythm next turn to a random ally, and on kills, 2 to all allies. After the attack, restores SP to the allies with low SP (1 + highest Resonance, up to 4).
Passive — That... was Indeed a Rhythm: Gains 2 Rhythm at Turn Start. Recovers HP and SP on kills, doubled for kills with this E.G.O. It also recovers at the end of turns in which his SP decreased.
SP paid in installments: For 2 turns after the attack, he loses 8 SP at Combat End.

How to Use

Higher SP makes Heads more likely and extends the reuse chain, so fire it while his SP is high.
Fire it at multiple enemies with Bleed and Burn. Against a single enemy, it struggles to show its value.
Its Clash Power is lowish, so land it as a one-sided attack. The self-damage piles up, so HP management is required.
It requires 3 Wrath, 2 Lust, 1 Sloth, 1 Pride, and 1 Envy, with an Awakening Sanity cost of 10.
