Vantom starts the fight with 9 stacks of Slippery. While Slippery is active, every single attack hit consumes one stack and deals exactly 1 damage, regardless of the attack's power. Only after all 9 stacks are depleted does normal damage apply.

Additionally, Vantom's tail slowly rises and when it hovers overhead deals heavily amplified damage. Every third turn, Dismember adds 3 Wounded status cards to the player's deck, clogging the hand.

• Burn through Slippery with low-cost multi-hit attacks — Slippery consumes one stack per hit, so multi-hit cards like Pummel or Shivs are the most efficient tools. Burning all 9 stacks quickly unlocks full damage output.
• Deal as much damage as possible before each Dismember — Dismember arrives every third turn like clockwork. Push maximum damage on Turns 1–2 before the hand gets clogged with Wounded cards.
• Hold burst damage for after Slippery ends — The moment all 9 stacks are consumed is your prime burst window. Save strong attack cards and potions for that turn to maximize the damage spike.
• Manage Wounded cards actively — Accumulating Wounded cards disrupts draw quality and card efficiency. Exhaust tools and discard mechanics can remove Wounded and keep the deck functional.

• Load up on multi-hit, low-cost attack cards (Pummel, Shivs) to rapidly deplete the 9 Slippery stacks
• Reserve powerful single-hit attacks and potions for the turn immediately after Slippery ends
• Bring Exhaust tools to purge Wounded cards added by Dismember
• Deal maximum damage on Turns 1–2 before each Dismember arrives to stay ahead of hand disruption
• Prioritize multi-hit attack cards when building your deck through Act 1
