GUIDEMechanics and How to Use

At a Glance

A Pride Pierce E.G.O geared more toward support than offense: it hands out Poise to all allies and grants automatic healing every turn after use.

Core Mechanics

  • Distributing Poise: Before attacking, gives all allies Poise Potency equal to the highest Resonance, up to 4, or 6 at Threadspin Ⅲ. With 3 or more Pride Resonance, it also grants Poise Count and Shallow Exhale.
  • Passive — Breath: From the turn after use, Nebulizer α increases, up to 5. At Turn End, it heals a number of allies equal to the highest Resonance, in order of lowest HP ratio, by α% of their max HP each.
  • Allies with plenty of Poise: If a healed target has at least 20 Poise Potency, the heal triggers once more. Shallow Exhale increases the Count by 1 when an Identity with at least 20 Poise Potency gains Poise.
  • Self-buffs: At Threadspin Ⅲ, it increases her own Poise Count on hit and raises Critical damage, up to 40% at Threadspin Ⅳ.
  • Corrosion skill: If her Poise Potency is below 20, she gains Poise up to 20 and spends max HP equal to 2% per Poise gained, without being staggered or killed. The Awakening effects still apply.

How to Use

  • Rather than waiting until things get dangerous, use it early in the fight to start accumulating the automatic healing.
  • Use it with 3 or more Pride Resonance to hand out Poise Count as well.
  • Its attack is modest (2 Coins with 3 Attack Weight), so Poise and healing are the goal. The fewer allies there are, the slower the healing likely is.

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

ANALYSISThreadspin

  • Ⅱ: Unlocks the passive, completing the core of Poise distribution and healing.
  • Ⅲ: Adds a higher Poise distribution cap, her own Poise gain, and the Critical buff.
  • Ⅳ: Increases power and the Critical buff, but is likely a low priority.
