GUIDEMechanics and How to Use

At a Glance

A Gloom E.G.O that drains enemy SP with a high-power 1-Coin Blunt attack and pushes enemies that have SP.

Core Mechanics

  • High power and SP damage: A 1-Coin Blunt attack reaching up to 33 on Heads (38 at Threadspin Ⅲ). Triggers Tremor Burst on Heads Hit and deals 15 SP damage on hit (25 at Threadspin Ⅲ).
  • Extra damage (Threadspin Ⅲ): Deals an additional 30% of the damage dealt when the target is staggered, in Low Morale, or panicking.
  • Multi-target and Sinking (Threadspin Ⅳ): Attack Weight becomes 3, and it inflicts 2 Sinking on hit. Used against multi-part enemies, it can likely drain SP all at once.
  • Corrosion skill: Inflicts Tremor and Sinking on hit, with the amount growing from 5 to 7 to 10 through Threadspin. Even against enemies without SP, Sinking turns into Gloom damage.
  • Passive — Wave of Depression: Targets attacked by the rightmost skill on the panel take (Gloom Absolute Resonance×2) SP damage at the end. A minor bonus.

How to Use

  • Use it on enemies with SP to drain it and push them into Low Morale or Panic. Lower enemy SP makes Heads less likely for them, likely tilting Clashes in your favor too.
  • Its maximum power is high, so on Heads it can win Clashes against many attacks.
  • Against enemies without SP, the Corrosion skill's Sinking is the main tool, but when used through E.G.O Corrosion it attacks friend and foe alike.
  • It requires 4 Gloom, 2 Pride, and 1 Lust. The Gloom cost is heavy, so pick its moments carefully.

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

ANALYSISThreadspin

  • Ⅱ: Unlocks Wave of Depression, but the effect is small.
  • Ⅲ: Raises Base Power and SP damage, and adds extra damage against staggered targets and similar. Against a single enemy, this is likely enough.
  • Ⅳ: Adds multi-target attacks and Sinking infliction. Valuable when hitting multi-part enemies.
