GUIDEMechanics and How to Use

At a Glance

A multi-target Wrath Pierce E.G.O that attacks an enemy with accumulated Burn and Sinking to activate its +1 Coin Power bonus.

Core Mechanics

Coin Power bonus: Before attacking, gains +1 Coin Power if the main target's combined Burn and Sinking Potency reaches 15, lowered to 10 at Threadspin Ⅳ. Its unboosted Clash range is only 4–16, so plan around meeting this condition.
Inflicting Burn and Sinking: Coin Ⅰ inflicts Burn Potency and increases Sinking Count; Coin Ⅲ inflicts Burn equal to Sinking Potency ÷ 3, up to 5. The Power condition is checked before attacking, so this skill's own applications cannot satisfy it.
Shattered World and Coin Ⅳ: If they hit without being broken, Coin Ⅱ applies Shattered World for this turn and next turn, and Coin Ⅳ triggers Burn once, consuming 1 Burn Count. Shattered World multiplies Burn damage taken by 1.2, excluding special Burn types.
Poise: Before attacking, gains Poise equal to the highest Resonance, up to 7, improving Critical chance. Coin Ⅲ increases Burn Count on a Critical Hit.
Passive — Skyweaving: His Base Attack Skills inflict 1 additional Burn or Sinking Potency on enemies with Shattered World, up to 8 per turn. This mainly helps on the following turn and is a secondary benefit.

How to Use

Use other Identities to build Burn and Sinking first, then attack a target that meets the threshold.
Use the Power bonus for damage on the activation turn, then build Burn next turn while Shattered World remains.
Mirror Dungeon Gifts can make this E.G.O especially strong by supporting its setup. Elsewhere, the team must supply what it needs.
Costs 4 Wrath, 2 Gloom, 2 Pride, and 4 Envy. Awakening costs 30 SP. Corrosion uses negative Coins; understanding its behavior during E.G.O Corrosion is sufficient for this guide's basic plan.

ANALYSISThreadspin

Ⅱ: Only unlocks Skyweaving; the Coin Power condition is not yet available.
Ⅲ: Adds the Coin Power condition at a threshold of 15 and improves Coin Ⅰ's Burn and Sinking application, establishing its main role.
Ⅳ: Lowers the threshold to 10 and raises Coin Ⅰ's Sinking Count to 3. This can be a lower-priority upgrade.

SYNERGYTeams and Synergies

Liu Assoc. South Section 3: All 3 Base Attack Skills inflict Burn, and he supplies Wrath and Envy resources.
Effloresced E.G.O::Spicebush: S3 increases Sinking Count on hit and supplies Pride. S2 inflicts 2 Sinking next turn, while successful Evades inflict 1 Sinking. The Count helps maintain Sinking but does not increase the Potency used for this E.G.O's threshold. S2's Potency arrives next turn. Using a Base Skill and this E.G.O in the same turn also requires multiple action slots.
The House of Spiders: The Index Nursefather: All 3 attack skills inflict Sinking, and he supplies Gloom and Pride resources. Burn needs another source.
