GUIDEMechanics and How to Use

At a Glance

A multi-Coin Blunt E.G.O for Sinking teams that, fired while his SP is high, unloads up to 8 Coins and inflicts heavy Butterfly.

Core Mechanics

Unfocused Volley: Attack Weight is 3, but each Coin picks one target. The first Coin hits the main target. Against a single enemy, all Coins hit that enemy.
Coin reuse: The third Coin lowers his SP by 2–6 on hit and is reused while his SP is 0 or higher (up to 5 times). The higher his SP, the more reuses.
Butterfly: A special Sinking inflicted on each hit, up to 15. Each Butterfly becomes a Dead Butterfly with the chance of landing Heads, or a Living Butterfly otherwise.
Passive — Lament: If he has a negative effect at Turn End, he gains 1 Attack Power Up next turn. +15% damage against targets in Panic or E.G.O Corrosion.
Heavy requirements: 7 resources in total: 1 Lust, 2 Sloth, 2 Gloom, and 2 Envy, with a Sanity cost of 25.

How to Use

Fire it when his SP is close to full. With low SP, the reuse chain does not last.
It pays off when fired at a single enemy already loaded with Sinking.

KEYWORDSEffect Glossary

Butterfly: Special Sinking Default: 0; maximum: 15 This effect's Potency is The Living; its Count is The Departed. When taking damage, heal the attacker's SP by The Living ÷ 4 (minimum 1, rounded down). If SP is below 0 when taking damage, take Gloom damage equal to Sinking Potency ÷ 5 for every 1 The Departed (maximum Gloom damage: 30, rounded down; halve this damage against targets without SP). At Turn End, reset The Departed to 0. Inflict Sinking equal to The Living, then convert The Living into The Departed. External effects cannot increase this effect's infliction amounts. Extra Sinking infliction effects add Sinking instead of extra Butterfly. Remove this effect when both The Living and The Departed reach 0.
Sinking: When hit by an attack skill, take fixed SP damage equal to the Potency (converted to Gloom damage for Abnormalities). After taking damage, reduce Count by 1.
Attack Power Up: For 1 turn, increase the Final Power of attack skills by the value.
