A high-risk Envy Blunt E.G.O that stacks Surgery to gain damage and Haste in exchange for cutting max HP.
Core Mechanics
Surgery: Each point gives +20% damage dealt and −20% max HP, and grants Haste equal to its value every turn. He dies when it reaches 5.
Inflicting Surgery: Awakening grants 1 Surgery next turn after the attack (Threadspin Ⅲ), and Corrosion grants 2. It stacks with every use.
Passive — Final Augment: Using this E.G.O below 25% HP grants Attack Power Up, Defense Power Up, and 3 Haste every turn, and he dies 3 turns later.
Corrosion skill: There is no mention of being unable to distinguish friend from foe.
Paralyze: Inflicts 3 Paralyze on Heads Hit. It is not worth the risk of cutting HP, so treat it as a minor extra.
How to Use
Keep Surgery at 1–2 and watch his HP. His max HP drops, so handle unfavorable Clashes with Defense skills and avoid taking hits.
In consecutive battles, stacking Surgery early lets later waves start with high damage.
Final Augment is single-use late-game damage. It assumes adjusting his HP before triggering it.
It requires 2 Sloth, 1 Pride, and 2 Envy, with a Sanity cost of 20 for both Awakening and Corrosion.

SYNERGYTeams and Synergies
Blade Lineage Mentor: Has Yield My Flesh and To Claim Their Bones, whose damage grows with HP lost, and his passive survives lethal damage once.
N Corp. Großhammer: Has Drive, which gains Coin Power below 50% HP, and a passive that grants 3 Protection and more below 50% HP, so he makes good use of a lowered-HP state.
