Ascension Levels

Ascension is a per-character difficulty system in Slay the Spire 2. Each ascension level adds a cumulative modifier that makes runs progressively harder. You unlock the next level by completing a run at your current highest ascension. All modifiers stack, so Ascension 10 includes every modifier from levels 1 through 10.

Cumulative

Each level includes all previous modifiers. Ascension 10 has all ten active at once.

Per-Character

Ascension progress is tracked separately for each character. Beating Ascension 3 with Ironclad does not unlock it for Silent.

Unlock Requirement

Beat Act 3 with a character to unlock Ascension mode. Then beat each level to unlock the next.

Swarming Elites

Map

The map generates more elite encounters than normal. You will encounter elites more frequently on every path, making it harder to avoid them.

Strategy

Build your deck to handle elites earlier. Prioritize strong damage output and reliable block generation from the first few card rewards. Elite fights offer the best relics, so a combat-ready deck turns this modifier into an advantage.

Weary Traveler

Resources

When Ancients heal you between acts, they restore only 80% of your missing HP instead of the full amount. This means you carry more damage into subsequent acts.

Strategy

Preserve your HP more carefully. Take less unnecessary damage in fights by prioritizing block. Rest sites for healing become more valuable. Consider potions and self-healing cards as higher priorities.

+ all modifiers from levels 1–1

Poverty

Resources

All gold rewards from combat and treasure chests are reduced by 25%. This significantly limits your purchasing power at shops throughout the run.

Strategy

Be more selective at shops since you can afford fewer purchases. Prioritize the most impactful buys — key relics and card removal over potions. Gold-generating relics and events become much more valuable.

+ all modifiers from levels 1–2

Tight Belt

Resources

Your maximum potion capacity is reduced by 1 from the start of the run. This limits your ability to stockpile potions for tough fights.

Strategy

Use potions more aggressively rather than hoarding them. With fewer slots, holding potions "just in case" costs more opportunity. Relics that expand potion capacity or provide potion-like effects gain value.

+ all modifiers from levels 1–3

Ascender's Bane

Penalty

You begin every run with the Ascender's Bane curse in your deck. This unplayable card clogs your draws and cannot be removed through normal means — it can only be exhausted or transformed.

Strategy

Cards and relics that exhaust from your hand or deck become essential. Prioritize exhaust synergies or ways to minimize the curse impact. A smaller deck suffers more from the dead draw, so consider whether thinning your deck or expanding it helps more.

+ all modifiers from levels 1–4

Gloom

Map

The map generates fewer rest site nodes than normal. This reduces your opportunities to heal and upgrade cards between combats.

Strategy

Plan your path carefully to hit the rest sites that do exist. Healing from other sources (potions, events, relics, self-healing cards) becomes critical. Consider whether resting or upgrading is more important at each site since you get fewer chances for both.

+ all modifiers from levels 1–5

Scarcity

Resources

The chance of seeing rare cards and pre-upgraded cards in card rewards is reduced. You will see more common and uncommon options in your card selections.

Strategy

Value rare cards more highly when they do appear. Smithing at rest sites becomes more important since you see fewer pre-upgraded cards. Shops may offer rare cards you cannot find elsewhere, making gold even more valuable.

+ all modifiers from levels 1–6

Tough Enemies

Enemies

All enemies gain increased HP across the board. Normal, elite, and boss enemies all take more hits to defeat, extending every combat encounter.

Strategy

Scaling damage becomes more important than frontloaded damage. Cards and relics that grow stronger over multiple turns help handle the extra enemy HP. Strength/Focus scaling and damage-over-time effects like Poison gain relative value.

+ all modifiers from levels 1–7

Deadly Enemies

Enemies

All enemies deal increased damage with their attacks. Combined with Ascension 8, enemies are now both tankier and hit significantly harder.

Strategy

Block generation is paramount. You need to consistently generate enough block to survive heavier hits every turn. Defensive scaling through Dexterity, Frost orbs, or other repeatable block sources becomes essential. Avoid taking unblocked hits whenever possible.

+ all modifiers from levels 1–8

Double Boss

Enemies

The Act 3 boss fight features two bosses simultaneously instead of one. This is the ultimate test of deck strength, requiring you to handle two boss-level threats at the same time.

Strategy

Your deck needs to handle massive sustained damage output while maintaining strong defense. Area-of-effect damage and multi-target attacks gain enormous value. Build your entire run with the double boss in mind — every card choice should consider whether it helps in that final fight.

+ all modifiers from levels 1–9

Ascension 10 — The Ultimate Challenge

At Ascension 10, all ten modifiers are active simultaneously. You face swarming elites, reduced healing, less gold, fewer potion slots, a starting curse, fewer rest sites, scarcer rare cards, tankier enemies, deadlier attacks — and must defeat two bosses at the end of Act 3. Only the most skilled players reach this pinnacle of difficulty. Beating Ascension 10 with every character is considered one of the greatest accomplishments in the game.
