Slay the Spire 2 Getting Started Guide: Pro Tips for Your First 10 Hours

If you just bought Slay the Spire 2 and you're confused about why you keep dying on floor 8, here's the thing nobody told me: the game wants you to skip most of the cards it offers you. Seriously. Every fight gives you a card reward and you should probably take about one in three.

It sounds wrong. More cards equal more power, right? Wrong. Every card you add makes your deck thicker, which means you see your best cards less often. A 15-card deck cycles every 3 turns. A 30-card deck cycles every 6 turns. Most hallway fights should be ending by turn 4 or 5. If your best damage card is buried at the bottom of a 30-card deck, you might literally never draw it.

Start With Ironclad

Don't get cute and pick Silent or Defect for your first run. Ironclad heals 6 HP after every combat thanks to Burning Blood. That alone will save you 20-30 HP per act when you're learning enemy patterns. His damage is straightforward — play attacks, gain Strength, hit harder. No orbs to manage, no poison stacks to track, no Souls to bank.

Silent is too fragile for a new player. One bad draw into an elite fight and your run is over. Defect needs orb management knowledge you don't have yet. Necrobinder and Regent are new characters with mechanics (Souls and Quests) that assume you already understand the fundamentals.

Ironclad. Bash things. Learn the game.

The First Three Floors

Your starting deck is 5 Strikes, 5 Defends, and Bash. Strikes deal 6 damage. Defends block for 5. They're bad. Your goal from floor 1 is to replace them with better cards and eventually remove them entirely.

First three card rewards: prioritize anything that deals 12+ damage for 1 energy. Carnage, Hemokinesis, Anger, Pommel Strike. You need front-loaded damage to survive Act 1 elites and the first boss. Do not take scaling cards yet — Inflame is good but not before you have three solid attacks. Do not take setup powers. Do not take niche synergy cards.

After floor 3, look at your map. Plan a route with 1-2 campfires before the boss. Upgrade Bash at the first campfire — upgraded Bash applies Vulnerable for 3 turns instead of 2, which is a huge damage increase.

The Merchant — Spend Gold Wisely

First shop: remove a Strike. Costs 75 gold. Best value in the game.

Second shop: remove another Strike or buy a good relic if one shows up. Save potions for elites and bosses.

Do not buy cards at shops unless it's something your deck desperately needs. The markup isn't worth it early on. Card removals and relics are better long-term investments.

Gold management tip: the Act 2 shop often has a powerful relic that can define your build. Try to have 150-200 gold saved when entering Act 2. That means skipping small purchases in Act 1.

Elites — When to Fight, When to Flee

Act 1 elites: fight only if you have at least one upgraded damage card, a damage potion, and 35+ HP. Gremlin Nob gains 3 Strength every time you play a Skill — including potions. If your deck is skill-heavy, avoid Nob at all costs. Lagavulin debuffs your Strength and Dexterity after waking up, so you want to burst it fast. Sentries are three enemies that fill your deck with status cards — AoE helps enormously.

One elite in Act 1 is usually safe if your deck is decent. Two is pushing it. Skip elites if you're below 30 HP or lacking upgraded attacks.

Act 2 and 3: elites become more rewarding relative to hallway fights. By then your deck should have a plan, and elite relics are permanent power. Super elites (flame icon on map) have bonus HP but guarantee a relic drop — always worth it if you're healthy.

The Ancients System for Beginners

After you beat an act boss, you don't get a boss relic like in the original. Instead, three Ancients offer you blessings. Each blessing has a bonus and a permanent penalty.

As a beginner, here's a simple rule: take the blessing whose penalty hurts your playstyle the least. If you find yourself resting at campfires a lot, don't take the one that blocks campfire healing. If your deck is running smoothly at 3 energy, you probably don't need the +1 energy blessing with the HP penalty.

The Ancients are one of the biggest StS2 changes. In the original you'd just grab an energy relic and move on. Here you're making a strategic tradeoff. Read all three options before clicking. I've killed runs by picking the shiny-looking blessing without checking the downside.

Co-op Mode — A Quick Note

Slay the Spire 2 has 4-player online co-op. It's a completely different experience — enemies have more HP, card synergy between players matters, and communication is half the battle. For your first 10 hours, stick to solo. Learn the basics before adding multiplayer chaos.

If You Keep Dying In Act 2

Act 2 is the filter. If your deck made it through Act 1 but keeps dying to hallway fights in Act 2, the problem is usually one of two things: either you added too many cards (deck is too thick, can't draw your good stuff), or you don't have AoE. Triple-slaver fights and bird swarms punish single-target decks. Pick up one Whirlwind, Cleave, Immolate, or similar before Act 2 starts.

Also: your deck should have a clear identity by mid-Act 2. If you can't describe your win condition in one sentence, your deck is probably a pile of random decent cards that don't work together. "I deal damage" isn't enough. "I exhaust skills for free block while Body Slam scales off it" is a plan.

Expect 30-50 hours before your first Heart kill. StS2 is genuinely harder than the original. Learning enemy patterns matters more than learning card combos, especially early on. Every death teaches you something — which sounds like motivational poster nonsense but is literally how the game works. You die to Hexaghost because you didn't know it scales damage to your max HP. Now you know. Next run, you'll path differently.
