Slay the Spire essentially invented the deckbuilder roguelike genre and remains its best execution. Each run climbs a three-act spire, battling enemies with a card deck you build from scratch. The genius is in how relics (passive items) synergize with specific card combinations to create broken combos — Shuriken (gain Strength on 3 attacks played) with a deck full of zero-cost attacks creates infinite scaling. Four characters with completely distinct card pools and playstyles provide hundreds of hours of variety. The Ascension system (20 difficulty levels per character) ensures the game stays challenging for thousands of hours. Slay the Spire 2 is in development, but the original remains a masterpiece.
Slay the Spire features distinct areas with increasing difficulty. This guide covers every major location in progression order — what to do, what to get, and when to move on. For the step-by-step path, see our walkthrough.
Area Progression Order
| Order | Location | Difficulty | Key Rewards | Recommended Build |

| 5 | Unknown Events | All acts | Free card removals, bonus relics, max HP changes, unique upgrades | Ironclad |
Exordium — Starting Area
Act 1 with the weakest enemies but crucial build foundation. Elite fights here drop relics that define your run. The Act 1 boss (one of three: Slime Boss, Guardian, Hexaghost) tests your damage output. Prioritize fighting 2-3 elites in Act 1 for essential relic acquisition.
| Attribute | Detail |
|---|---|
| Difficulty | Act 1 (floors 1-16) |
| Key Rewards | 2-3 elite relics, core card picks, boss relic choice |

| Key Equipment | Wraith Form |
What to Do Here
- Learn the basics of deck building — this is where you practice without heavy punishment.

The City — Early Game
Act 2 ramps difficulty with multi-enemy fights and powerful elites (Book of Stabbing, Gremlin Leader, Taskmaster). Enemy damage and HP increases significantly. Your deck needs to handle both single-target bosses and multi-enemy hallway fights.

- Complete all objectives for maximum rewards.
- Prepare for the difficulty spike in The Beyond.
The Beyond — Mid Game
Act 3 features the hardest regular enemies and devastating elites (Giant Head, Nemesis, Reptomancer). Your deck should be fully online with a clear win condition by now. The Act 3 boss is the final challenge — Awakened One, Time Eater, and Donu/Deca each punish different strategies.
| Attribute | Detail |

The Heart — Late Game
The optional superboss accessible by collecting all three colored keys during the run. The Heart has 750 HP (A20: 800), deals multi-hit attacks scaling each turn, and punishes card spam with a 15-card-per-turn cap. Beating the Heart is the community's true victory condition.
| Attribute | Detail |
|---|---|
| Difficulty | Floor 51 (superboss) |
| Key Rewards | True victory, score bonus, achievement/unlock |

Unknown Events — Endgame
Question mark nodes with narrative encounters. Notable events: Face Trader (swap face for relic), Golden Shrine (upgrade or gain gold), Dead Adventurer (chance for relic or damage). Learning which events appear in which act and their optimal choices is an advanced skill.
| Attribute | Detail |
|---|---|
| Difficulty | All acts |
| Key Rewards | Free card removals, bonus relics, max HP changes, unique upgrades |
| Recommended Build | Ironclad |
| Key Equipment | Corruption |
What to Do Here
- This is endgame. Best-in-slot gear and a perfected build are mandatory.
- See our boss guide for endgame fight strategies.
- The reward loop: clear content → upgrade → push harder content.
- Experiment with Modded Characters for variety once you've mastered the meta.
Exploration Tips
- Clear areas in order — Exordium → The City → The Beyond → The Heart → Unknown Events. Skipping areas means missing resources you'll need later.
- Check every corner — Hidden caches and secrets are often in non-obvious locations.
- Match your equipment — Some areas favor different equipment types.
- Read the walkthrough — Our walkthrough provides exact progression milestones for each area.
- Don't rush — Clearing an area fully gives more resources than speedrunning two areas.
