GUIDEMechanics and How to Use

At a Glance

A Sloth Blunt E.G.O that stacks Tremor on herself and layers Tremor Bursts across 3 targets, staggering enemies while also restoring SP.

Core Mechanics

Tremor Burst: Triggers Tremor Burst (Tremor Count −1) on second Coin hit. From Threadspin Ⅲ, the first Coin also bursts if the target is not staggered, in Low Morale, or panicking, and at Threadspin Ⅳ it bursts twice.
Tremor on herself: Before attacking, her Tremor Count increases by (highest Resonance + 5), up to 10, and by 5 more on first Coin hit. Useful for Identities that reference their own Tremor Count.
SP recovery: After the attack, restores 10 SP if any target is staggered, in Low Morale, or panicking. Against its Sanity cost of 20, this effectively makes it 10.
More damage against SP below 0: From Threadspin Ⅲ, if the target's SP is below 0, +1% damage per point below 0, up to 45%.
Passive — A Gaze in the Shadows: +1 to the Tremor Count allies gain from skill and Coin effects, twice per turn. +2 if the target is staggered or similar.

How to Use

In Tremor teams, wear enemies down to the brink of Stagger before firing it. The extra bursts require the enemy not to be staggered.
If Tremor infliction is the goal, it is useful even at Threadspin Ⅱ, which unlocks the passive.
The Corrosion skill has 5 Attack Weight and high damage, but it cannot distinguish friend from foe, so when used through E.G.O Corrosion, allies also become targets.

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

ANALYSISThreadspin

Ⅱ: Unlocks A Gaze in the Shadows. If the passive is the goal, you can stop here.
Ⅲ: Adds the damage increase against SP below 0, 5 Sinking infliction, and extra Tremor Bursts. For damage, take it at least this far.
Ⅳ: Further increases the number of Tremor Bursts and raises the Corrosion skill's Base Power.

SYNERGYTeams and Synergies

Molar Boatworks Fixer: S1 (Pride) and S2 (Sloth) supply the required affinities, and her skills are strengthened by her own Tremor Count.
Zwei Assoc. West Section 3: Her own Tremor Count turns into Defense Level and power. She supplies Pride and Gluttony but has no Sloth skills, so cover it with other Identities.

KEYWORDSEffect Glossary

Tremor: When attacked by skills that trigger Tremor Burst, raise the Stagger Threshold by the effect’s Potency. At the end of the turn, reduce the Count by 1.
Sinking: When hit by an attack, take fixed SP damage by the effect’s Potency. (Non-SP Units take Gloom damage instead.) Then, reduce its Count by 1.
