GUIDEMechanics and How to Use

At a Glance

An Identity for longer battles who repeatedly follows Prescripts with marked skills, builds Procuration [Hermes] to 9, and unleashes Furioso-Replica before rebuilding.

Core Mechanics

  • Procuration [Hermes] (maximum 9): His always-active Oracle Device [Caduceus] passive grants 1 when he uses a Prescript-marked skill. With his combat passive Imitation of a Life active (1 Gluttony, 1 Gloom, and 1 Pride Owned; unlocked at Uptie Ⅱ), Unbreakable Coin hits from Base Attack Skills grant 1, and Attack End grants more equal to the remaining Unbreakable Coins. He can gain only Unlock tier + 2 per turn; before Unlock - II, he cannot hold more than 8.
  • Furioso-Replica: At Turn Start with 9 Procuration [Hermes], S3 transforms into this skill, with only 1 copy allowed on the dashboard. If Procuration [Hermes] increases to 9 during the turn, Imitation of a Life checks this at Turn End and changes a Base Skill into S3 next Turn Start if S3 is absent. All 9 Coins are Unbreakable, and the attack distributes its hits across multiple targets. After attacking, inflicts 5 Burn, 3 Bind, and 3 Fragile next turn on every target it hit, then consumes all Procuration [Hermes].
  • Prescripts and Unlock: At Turn Start, up to 2 Base Attack Skills on his dashboard receive Prescript marks. This process is disabled while he is Staggered, unable to act, in Panic, or in E.G.O Corrosion. The task changes with Unlock tier: initially use a marked skill; at Unlock - I, land a hit with it. Before Unlock - II, fulfilling the Prescript grants 4 SP and 1 Grace of the Prescript at Turn End; if the main target has the Prescript's Target effect, this becomes 8 SP and 3 Grace. At Unlock - II, fulfilling Prescript: [Device] III grants only 4 SP; the reward becomes 8 SP and 3 Grace only when Procuration [Hermes] reaches 9 through fulfillment. Reaching 3/6/9 Grace grants Unlock - I/II/III. Failing a Prescript grants 5 Karmic Consequence, except at Unlock - III. Slash-separated values indicate different Uptie tiers.
  • Wound-casing Mask: Gained on his first appearance in the stage, granting +2 Offense Level and -2 Defense Level. His first Stagger of the battle or first use of Furioso-Replica changes it at Turn End into Sizzling Wound: +3 Offense Level, -3 Defense Level, -25% damage taken from unopposed attacks, +15% Unbreakable Coin damage from Base Attack Skills, and 1 Burn and 1 Bleed at Turn Start. If the change was triggered by Stagger, also removes that Stagger, except Forced Stagger.
  • Poise and Sinking: S1–S3 gain Coin Power from his own Poise Potency and the target's Sinking Potency, with the bonus starting at a combined 6 and reaching up to +2 depending on Uptie tier.

How to Use

From turn 1, gather 1 Gluttony, 1 Gloom, and 1 Pride resource to activate Imitation of a Life. Use Prescript-marked skills each turn to avoid Karmic Consequence while building Procuration [Hermes]. Once you reach 9 at Unlock - II or higher, use Furioso-Replica and rebuild. The gain limit puts the first use around turns 5–6 and later uses roughly 3–4 turns apart when fulfillment and hits go as planned, favoring longer fights such as boss battles. His Mask removes the first eligible Stagger once and changes into his enhanced state, helping him recover from an early Stagger.
