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.
Starting Slay the Spire can feel overwhelming. This guide tells you exactly what to focus on during your first hours so you don't waste time on things that don't matter yet.
What Kind of Game Is This?
Slay the Spire is a card-game game built around deck building and relic synergies. The core loop involves mastering these systems to progress through increasingly challenging content.
What to expect: Time investment in learning mechanics, experimentation, and gradual mastery. The game rewards patience and knowledge.
Choosing Your First Build
| Build | Beginner Rating | Why |
|---|---|---|
| Ironclad | Excellent for beginners | Stack Strength through Demon Form or Inflame, play heavy attacks that multiply Strength, and use Corruption to make all Skills free while generating infinite value with exhaust synergies. |
| Silent | Excellent for beginners | Apply Poison with Noxious Fumes (auto-apply each turn) and Deadly Poison, then use Catalyst to double stacks. Use Wraith Form to survive while Poison finishes enemies. |
| Defect | Excellent for beginners | Build Focus with Defragment and Consume, channel Frost orbs for passive block, and use Lightning/Dark orbs for damage. Echo Form doubles your first card each turn. |
| Watcher | Good (but demanding) | Enter Wrath, deal doubled damage, exit to Calm for energy, repeat. Use Scry to ensure you draw the right cards at the right time. Reach Divinity Stance for triple-damage burst turns. |
| Modded Characters | Not recommended first | Varies by mod — each modded character introduces unique mechanics and card pools. |
Our recommendation: Start with Silent. The Silent focuses on Poison (damage that ticks every turn) and Discard synergies. Wraith Form (+2 Intangible, -1 Dex per turn) makes you nearly invincible for 2-3 turns. Catalyst doubles your current Poison stacks, enabling exponential scaling. The Silent also has strong Shiv builds (zero-cost 4-damage attacks) with Accuracy and Shuriken.
Avoid Modded Characters as your first pick. Steam Workshop mods add dozens of custom characters like The Hermit, The Disciple, and Downfall (play as enemies).
First Session Step-by-Step
Step 1: Learn deck building
Your deck starts with basic Strikes (damage) and Defends (block). After each combat, you choose one of three card rewards to add. Card removals (shops, events) thin your deck for consistency. The tension between adding powerful cards and keeping your deck small enough to draw them consistently is the core strategic decision. Upgraded cards at rest sites gain improved effects.
This is the foundation. Spend your first 15-30 minutes getting comfortable with how deck building works before worrying about anything else.
Step 2: Head to Exordium
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.
Clear the main content here before moving on. Everything teaches fundamentals you'll need later.
Step 3: Get Your First Upgrade
Look for Wraith Form — it's the most accessible early upgrade. Silent Power card granting 2 turns of Intangible (reduce ALL damage to 1). The strongest defensive card in the game. The Dexterity loss each turn afterward is manageable with Artifact charges or short fights. Wraith Form + Catalyst Poison = win condition against most bosses.
Step 4: Understand relic synergies
Relics are passive items gained from elites, bosses, events, and shops. The 180+ relics range from simple (Bag of Marbles: enemies start with 1 Vulnerable) to game-defining (Dead Branch: add a random card whenever you Exhaust a card). The best runs find relic + card combos that create infinite loops or massive damage scaling.
This is the system most new players overlook. Invest time here early — it pays off throughout the entire game.
Step 5: Push to The City
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.

The tension between adding powerful cards and keeping your deck small enough to draw them consistently is the core strategic decision. Upgraded cards at rest sites gain improved effects.
relic synergies
Relics are passive items gained from elites, bosses, events, and shops. The 180+ relics range from simple (Bag of Marbles: enemies start with 1 Vulnerable) to game-defining (Dead Branch: add a random card whenever you Exhaust a card). The best runs find relic + card combos that create infinite loops or massive damage scaling.
potion management
Potions provide one-time combat effects: damage, block, buffs, or debuffs on enemies. You can hold 2-3 potions and they're found randomly after combats. Don't hoard potions — use them during elite fights and act bosses. A well-timed Strength Potion can carry an otherwise losing elite fight.
event choices
Question mark nodes on the map trigger events with narrative choices that have gameplay consequences. Some events offer card removal, gold, relics, or max HP changes. Knowing event outcomes (or taking educated risks) is an advanced skill. The Neow's Blessing at run start is the most impactful event choice.
ascension levels
20 difficulty levels per character, each adding a permanent modifier (more enemy HP, less gold, harder elites, etc.). Ascension 20 requires mastery of every mechanic and significant luck management. Clearing A20 Heart kills on all four characters is the community's ultimate achievement.
Common Beginner Mistakes
1. Adding every card offered — deck bloat is the most common beginner mistake
A 30-card deck draws its key cards half as often as a 15-card deck. Skip cards that don't fit your build.
2. Hoarding potions 'for the boss' while dying to elites — use potions on elites
If you die on floor 23 with 3 potions unused, those potions were wasted.
3. Always choosing damage cards over block cards — you need both offense and defense
A deck with no block can't survive Act 2 multi-fights or Act 3 bosses.
4. Ignoring pathing on the map — plan your path through each act before moving
Route through elites early, campfires when you need them, and shops when you have gold.
5. Not learning enemy movesets — many deaths come from not knowing that Gremlin Nob punishes Skills, Book of Stabbing multi-hits more each turn, or Time Eater heals after 12 card plays
First 5 Hours Checklist
- Understand deck building and relic synergies
- Choose Silent as starting build
- Clear Exordium main content
- Acquire Wraith Form or equivalent upgrade
- Reach The City
- Remove Strikes (not Defends) at every opportunity — Strikes deal 6 damage which is irrelevant by Act 2. Defends at least provide 5 block which is always useful. A smaller deck draws your power cards more often.
- Boss relics (chosen after each boss) are the most impactful decisions in a run. Energy relics (+1 max energy) are almost always correct. Snecko Eye (randomize costs, draw 2 extra cards) is the strongest boss relic for most decks.
Tips for New Players
- Remove Strikes (not Defends) at every opportunity — Strikes deal 6 damage which is irrelevant by Act 2. Defends at least provide 5 block which is always useful. A smaller deck draws your power cards more often.
- Boss relics (chosen after each boss) are the most impactful decisions in a run. Energy relics (+1 max energy) are almost always correct. Snecko Eye (randomize costs, draw 2 extra cards) is the strongest boss relic for most decks.
- Take every elite fight in Act 1 that you can survive — the relics from elites in Act 1 define the trajectory of your entire run. Skip Act 1 elites only if your HP is dangerously low.
- Don't skip card rewards blindly. Evaluate every card against your current deck — sometimes a card looks bad in a vacuum but fills a critical gap (AoE, block, scaling).
- Potions win elite fights. Use Strength Potions, Dexterity Potions, and Focus Potions during elites instead of hoarding them. You'll find more potions before the boss.
- Rest sites: upgrade early (Acts 1-2), heal late (Act 3). Upgrading a key card in Act 1 pays dividends for the entire run. In Act 3, HP management is tighter so healing becomes more valuable.
- Learn enemy patterns — each enemy follows a fixed or semi-random attack pattern. The Gremlin Nob always starts with an attack buff. Lagavulin debuffs you if you stall. Knowledge of these patterns informs your play.
- Card draw is energy — drawing extra cards lets you play more good cards per turn. Offering (draw 5, lose 6 HP) and Battle Trance (draw 3) are powerful because card draw multiplies your turn quality.
- Act 2 multi-fights (Chosen, Slavers) are the number one run-ender. Ensure your deck has AoE damage (Whirlwind, Dagger Spray, Electrodynamics) before entering Act 2.
- The Heart fight requires specific preparation: high sustained block, scaling damage, and multi-hit mitigation (Intangible, Thorns). If going for the Heart, plan for it from Act 1.
Frequently Asked Questions
What is Ascension in Slay the Spire?
Ascension is a 20-level difficulty system for each character. Each level adds a permanent modifier: A1 increases elite damage, A2 raises enemy HP, A5 starts you with a Curse card, A10 gives bosses more HP, etc. Beating Ascension N unlocks N+1. Ascension 20 requires mastery of every game system.
What is the best character in Slay the Spire?
The Watcher is the strongest character due to Wrath Stance's double damage and the Calm→Wrath energy loop. Her A20 Heart win rate among top players is significantly higher than other characters. For beginners, the Ironclad is easiest due to his healing relic and straightforward Strength-scaling archetype.
How do you beat the Heart?
Collect all three keys (Blue from rest site, Green from elite, Red from event/chest) to access the Heart fight. The Heart has 750-800 HP, hits for 60+ damage, and caps you at 15 cards per turn. You need: consistent block (30+ per turn), scaling damage (Strength, Poison, Focus), and burst mitigation (Intangible, high single-turn block).
Is Slay the Spire 2 coming?
Yes, Slay the Spire 2 was announced and is in development by Mega Crit Games. It features new characters, mechanics, and a revised art style. The original game continues to receive community mod support and remains the gold standard of the deckbuilder roguelike genre.
