💡 Slay the Spire 2 — 25 Pro Tips

Advanced strategies collected from top Ascension 20 players. Internalize these to climb faster.

Deck Building

  1. Skip is often the best pick. A lean deck consistently draws its best cards. Only add cards that solve an immediate problem or define your archetype. Bloated decks lose to bad draws.
  2. Act 1 rewards damage. Pick 2-3 solid attack cards before taking defensive tools. You need to kill Gremlin Nob and Lagavulin — they punish slow decks.
  3. Card draw is the secret sauce. Battle Trance, Acrobatics, Coolheaded — these cards are deceptively powerful. Seeing more cards means more options, more consistency, fewer dead turns.
  4. Build around relics, not the other way around. If you find Kunai on floor 3, start looking for Shiv cards. Let early relics guide your build direction.
  5. Remove Strikes > Removes Defends. Strikes are the worst card in your deck. Defends at least block. Remove Strikes first unless you're in a pure-offense deck.

Pathing & Map Strategy

  1. Elites are good, actually. Elite fights are scary but give relics (permanent power) and more gold. Aim for 2-3 elites per act if your HP allows.
  2. Campfires: Upgrade > Rest. Upgrading a key card has permanent value. Rest only when you'll die otherwise. Smoke Bomb potion can save a doomed run.
  3. Plan your path before moving. Look for lines with a campfire before the first elite. Check the boss icon — it determines what you need to prepare for.
  4. Shop paths are premium. Shops let you remove cards, buy relics, and grab potions. A path with 2 shops beats one with 3 ? rooms.
  5. ? rooms are high variance. They can give free relics, gold, or card removes... or lose HP for nothing. Visit them when you have buffer HP or need to high-roll.

Combat Fundamentals

  1. Kill the right enemy first. In multi-enemy fights, target priority matters. Focus the scaling threat (Cultist, Exploder) over the immediate damage dealer.
  2. Intent reading is your superpower. Enemies telegraph their next move. If they're not attacking, you shouldn't be blocking. Maximize every turn.
  3. Potion timing wins runs. Don't hoard potions for the boss — using one to save 15 HP in a hallway fight is worth it. Health is a resource.
  4. Artifact strips debuffs. If you have an Artifact charge, use Flex/Speed Potion before eating the debuff. Free stats. Core interaction to master.
  5. Don't end turns with energy. Unspent energy is wasted damage or block. Plan card order to use every point.

Ascension 20 Survival

  1. A17+ enemies hit harder. The damage jump is real. Your deck needs more block than you think. Glacier, Leg Sweep, Shrug It Off become premium.
  2. A18+ elites are nightmares. Act 1 elite hunting becomes much riskier. Consider taking safer paths unless your Neow bonus is attack-heavy.
  3. A19+ bosses are brutal. Time Eater, Awakened One, and Donu & Deca all get significant buffs. Each requires a specific counter strategy. Prepare early.
  4. Double Act 3 boss demands full builds. You must beat two bosses. Builds that "barely" beat one won't survive. You need a genuinely broken deck.

STS2-Specific Tips 🆕

  1. Hemorrhage (Bleed) rewards patience. The new Bleed mechanic deals damage over time. Pair with Block-heavy cards to stall while enemies bleed out. Don't rush.
  2. Necrobinder minions tank hits. Minions can absorb single-target attacks. Position them between you and big hits. Bone Wall makes this even stronger.
  3. Shadow resource is a double-edged sword. Shadow boosts damage but costs HP. Only use it when the trade is clearly favorable. Soul Link can offset the HP cost.
  4. The new Act 1 event: "Spire's Bargain." Trade current HP for a random Rare relic. Worth it if you have sustain (Ironclad starting relic, Meat on the Bone). Skip otherwise.
  5. Early Access caveat. Card stats and mechanics will change. Follow patch notes closely. A build that's S-tier today might be B-tier tomorrow.

Common Mistakes to Avoid

  1. Taking every card offered. A 35-card deck is almost always worse than a 20-card deck with strong synergies.
  2. Forcing an archetype too early. Don't pick Catalyst before you have poison cards. Stay flexible through Act 1.
  3. Ignoring boss relics with downsides. Snecko Eye, Busted Crown, and Runic Dome have scary downsides but are often the right pick. Read the situation.
  4. Undervaluing card removal. Spending 75 gold to remove a Strike is almost always correct. Do it every shop if possible.
  5. Playing too fast. STS2 is a strategy game, not an action game. Take your time, calculate damage, check your draw pile. Every decision compounds.
