Slay the Spire 2 Flex-Type Strength — Temporary Strength Status Explained

The temporary Strength status is Strength with a curfew: "At the end of this turn, lose X Strength." You get the full attack bonus immediately — every attack this turn hits harder — and when the turn ends, the borrowed power goes back. It is a rental, and rentals are for big turns.

How it works

• Instant gain: the moment the status lands, you have X more Strength — every attack you play this turn adds X damage per hit.
• Automatic expiry: end of turn, you lose exactly X Strength. Nothing carries over; the status is not permanent scaling.
• Stackable: multiple sources of the status stack, raising both the instant bonus and the end-of-turn payback equally.
• The math: it is functionally "this turn, your attacks each deal X more" — and multi-hit attacks multiply the value, since every hit benefits.

Burst math that makes it shine

Temporary Strength rewards turns with many attack instances:

• Multi-hit attacks — a four-hit attack gains X × 4 total damage from one status.
• Zero-cost swarms — Claw lines, Shiv lines and repeated small attacks each collect the bonus.
• Whirlwind-style spenders — X-cost attacks that hit all enemies repeatedly convert rental Strength into board-wide damage.

How to use it without wasting it

1. Play the status first, attacks after — order is everything; the bonus only covers attacks played before the turn ends.
2. Front-load the big hits — if the turn runs short, the small attacks are what missed out, not the big ones.
3. Don't count on it defensively — Strength boosts attack damage, not block; plan the turn as an all-in aggression window.

Permanent Strength from cards like Demon Form scales every future turn; the temporary version is for the turn the boss needs to already be dead. Build both, and the spire's health bars stop being a conversation.
