Turn 1

How to beat Vantom

  • Slippery: your first 8 damaging hits each do 1 HP no matter their size, so do not open with your big hit.
  • Quiet turns: spend the two quiet turns (7 and 12 incoming) on cheap, multi-hit attacks to burn Slippery, then hit hard on the Dismember and Prepare turns.
  • Turn three is the test: block 26 (30) or eat it, and either way three unplayable Wounds land in your discard and dilute every later draw.
  • Prepare: every four turns the whole cycle gains 2 damage per hit, so plan to finish 173 HP before the second Dismember on turn seven.

Notes

  • 173 HP flat (183 at Ascension 8+), the Overgrowth boss.
  • Slippery is applied the moment it enters the room, so it is already in place on turn one.
  • A hit that is fully blocked does not use a stack, and damage below 1 is left alone.
