GUIDEMechanics and How to Use

At a Glance

A Burn-focused Slash E.G.O with 5 Attack Weight that spreads Burn and grows stronger with the total Burn across its targets. This guide assumes Threadspin Ⅴ.

Core Mechanics

  • Inflicting Burn: Coin Ⅰ inflicts 4 Burn on hit, plus another 6 on a Heads Hit, from Threadspin Ⅳ onward.
  • Total Burn bonuses: Before attacking, gains +1 Final Power per 6 total Burn Potency across all attack targets, up to +4, and +1% damage per Potency, up to +30%.
  • Passive — Ember: Active from the turn after E.G.O use. When using a Wrath skill or a skill that inflicts Burn, gains +1 Clash Power if the attack targets have at least 6 Burn Potency in total. On Clash Win, inflicts Burn equal to Wrath Resonance × 2 on the main target, up to 8 per skill.
  • Corrosion: Attacks random targets without distinguishing friend from foe. Has higher Burn-based bonus caps than Awakening: up to +6 Final Power and +45% damage. After use, gains Blazing: next turn, the first Base Attack Skill gains +2 Final Power, but each of its hits consumes the user's HP.

How to Use

  • Use it in a Burn team to spread Burn across several enemies at once.
  • Costs 5 Wrath, 1 Sloth, and 1 Gluttony, making Wrath the main resource requirement. SP cost: 20 Awakening, 20 Corrosion, 30 Overclock.
  • Its Power is low through Threadspin Ⅲ, so aim for Threadspin Ⅳ or higher if using it.

A practical guide based on the skill and passive descriptions below.(Updated: 2026-10-18)

ANALYSISThreadspin

  • Ⅱ: Unlocks Ember, which inflicts Burn equal to half the Wrath Absolute Resonance count on Clash Win at this tier.
  • Ⅲ: Raises Burn inflicted on a Heads Hit from 2 to 4.
  • Ⅳ: Adds 4 Burn on hit and raises the extra Burn on a Heads Hit to 6. Attack Weight rises from 3 to 5.
  • Ⅴ: Base Power rises from 12 to 14 and Coin Power from +8 to +12. Improves Ember, and the Corrosion Coin becomes Unbreakable.
