A multi-target Slash E.G.O with 5 Attack Weight that spreads Tremor and Sinking.
Core Mechanics
High-damage multi-target: A 2-Coin multi-target attack with 5 Attack Weight. The Corrosion skill targets friend and foe alike, so beware of friendly fire.
Tremor and Sinking: Coin Ⅰ inflicts 5 Tremor and triggers Tremor Burst, and Coin Ⅱ inflicts 4 Sinking.
SP recovery: If his HP is full after the attack, he recovers 10 SP at Turn End (15 at Threadspin Ⅳ) and gains 1 Attack Power Up next turn. It does not work once his HP drops.
Follow-up against low-SP enemies (Threadspin Ⅲ): If the target's SP is below 0, +1% damage per point below 0 (up to 45%). It grows when Sinking drains SP.
Passive — Insomniac Night: At Combat Start, inflicts Offense Level or Defense Level Down on all enemies equal to the number of staggered, Low Morale, or panicking enemies (up to 2 times per turn).
How to Use
Fire it at multiple enemies while keeping his HP up.
It requires 8 resources in total: 2 Sloth, 2 Gluttony, 2 Gloom, and 2 Pride, with a Sanity cost of 20.
