Power Cards
Complete guide to Power cards in Slay the Spire 2 — all persistent buff cards that define deck archetypes and win conditions.
Power cards in Slay the Spire 2 are a special subcategory of skill cards that provide persistent effects lasting the entire combat. Visually distinguished by their unique border and icon, powers are often the cornerstone of winning strategies, defining entire deck archetypes and enabling late-game scaling that makes boss fights manageable.
The most powerful powers create build-around effects that reward committed strategies. Corruption turns all skills into zero-cost cards at the expense of exhaustion, enabling incredibly fast and efficient turns. Demon Form provides enormous Strength gains each turn, turning every attack into a devastating weapon. Wraith Form grants intangible for multiple turns, providing near-invincibility during crucial moments. Each of these cards demands a deck built to support its specific playstyle.
Scaling powers like Defragment (Focus), Footwork (Dexterity), and Inflame (Strength) provide linear stat increases that compound over time. These are reliable, low-risk investments that strengthen every relevant card in your deck. The Defect relies especially heavily on scaling powers due to the Focus mechanic that amplifies orb effectiveness throughout every fight.
Draw and energy powers like Tools of the Trade, Machine Learning, and Berserk provide the engine that makes efficient decks possible. These powers improve your ability to access key cards and play more cards each turn, creating a snowball effect that grows stronger as fights progress.
When evaluating powers, consider the opportunity cost. Playing a power uses an entire turn's energy and does nothing immediate for board state. Powers are best taken when you have enough defensive tools to survive the turn spent playing them. In shorter hallway fights, cheaper powers or no powers at all may be preferable.
