Final Boss Prep

Late-game checklist and scaling audit

Final Boss Prep is a high-intent boss page for checking whether a deck has enough scaling, defense, and bad-hand recovery before the last fight.

Primary keyword: slay the spire 2 final bossMedium confidence
Primary check

Scaling plus bad-hand defense

Secondary check

Potion or relic insurance

Preparation note

A final boss page should not only celebrate a winning screenshot. It should ask how the deck reaches the winning state: what covers the first bad hand, what scales before the boss overwhelms the deck, and what backup plan exists when the main engine arrives late.

  • Bring one scaling plan that works under pressure.
  • Keep block density high enough for non-ideal opening hands.
  • Save potions for the turn the deck cannot naturally answer.
