GUIDEMechanics and How to Use

At a Glance

A multi-target Pride Slash E.G.O that upgrades from Thunderer to Higher Thunderer with each use and grows with Poise.

Core Mechanics

Thunderer and Higher Thunderer: After the attack, he gains 5 Thunderer, and if he already has Thunderer or Higher Thunderer, it switches to 5 Higher Thunderer. Both raise Offense and Defense Level and decrease by 1 at Turn End. Damage rises depending on which he has (Thunderer 15%, Higher Thunderer 27%; 25% and 45% at Threadspin Ⅳ). From Threadspin Ⅲ, Attack Weight also increases: 4 on the first use, 5 with Thunderer, and 6 with Higher Thunderer.
First-use refund (Threadspin Ⅳ): On the first use, with neither Thunderer nor Higher Thunderer, half of the resources and SP spent are returned.
Poise: Gains Poise Potency on use. The more Poise he has, the higher the Final Power (up to +3 at Threadspin Ⅳ). It does not increase Poise Count, so Poise Identities should be careful not to run out.
Passive — So is Writ, an Ode to Wine: At Turn End, he gains 1 of the required resource he has the least of. Damage also increases when Thunderer or Higher Thunderer decreases or is consumed, up to 15%.
Corrosion skill: 3 Unbreakable Coins. It is greatly strengthened while he has Thunderer or Higher Thunderer, so it shines from the second use onward.

How to Use

Fire the first use at low cost, and if needed, use it consecutively to advance to Higher Thunderer.
Use it with an Identity that has Poise, also aiming for extra Critical damage.
Its resources are 1 Sloth, 2 Gloom, and 4 Pride, skewed toward Pride.

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

ANALYSISThreadspin

Ⅱ: Unlocks the passive, letting him replenish resources on his own.
Ⅲ: Adds the Attack Weight increase from Thunderer and Higher Thunderer, making Attack Weight 5 and 6 from the second use on.
Ⅳ: Adds the first-use refund, a stronger damage increase, and a higher cap on Poise-based Final Power.
