GUIDEMechanics and How to Use

At a Glance

A lightweight multi-target Gloom Blunt E.G.O that can be fired for 4 resources with 3 Attack Weight.

Core Mechanics

  • Lightweight: Requires 2 Sloth and 2 Pride, with an Awakening Sanity cost of 20. A 2-Coin, 3-Attack-Weight multi-target attack with Clash Power 10–20. Threadspin does not raise its power or Attack Weight.
  • Sinking and Rupture: The first Coin inflicts 1 Sinking (2 at Threadspin Ⅳ), and the second Coin inflicts 1 Rupture (2 at Threadspin Ⅳ).
  • Centipede Venom: After the attack, inflicted equal to the combined number of negative effect types on herself and the main target (up to 5, 8 at Threadspin Ⅲ, 10 at Ⅳ). At Turn End, the bearer takes Gluttony damage equal to its value, then it is halved. More is added at 4 or more Gluttony or Gloom Resonance.
  • Passive — Reversal Death by Gu Poison: Each time she inflicts Sinking, she gains 1 Offense Level Up next turn, up to 2. With 3 or more Absolute Resonance, the cap becomes 3.

How to Use

  • Its damage is not enough to sweep enemies, so it is likely best fired to hit weaknesses or at staggered enemies.
  • Pair it with Identities that inflict Sinking to raise next turn's Clash Power.
  • As a ZAYIN E.G.O, choose between it and the fellow ZAYIN Snagharpoon (0801) based on resistances.
  • The Corrosion skill uses Minus Coins with low total power, so there is little reason to use it on purpose.

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

ANALYSISThreadspin

  • Ⅱ: Unlocks Reversal Death by Gu Poison. Considering the Threadspin cost, this is likely enough.
  • Ⅲ: Centipede Venom's cap becomes 8. A small change.
  • Ⅳ: Sinking, Rupture, and Centipede Venom each increase slightly. Low priority.
