Slay the Spire 2 Tier List: Ranking Every Character in Early Access

Slay the Spire 2 launched in Early Access in March 2026 with five characters, co-op multiplayer, and the kind of balance churn that makes any tier list a snapshot rather than a verdict. Patches are moving fast. Regent got a significant buff in v0.101.0. Silent had cards removed and restored. The meta will look different in three months.

That said, the community has played enough hours at this point to form genuine consensus on who's strong and who's struggling. What follows reflects post-v0.101.0 balance, the most current patch at time of writing. We'll update when significant balance changes land.

Five characters this time. Three returning veterans (Ironclad, Silent, Defect) and two newcomers (Necrobinder, Regent). Each character has 80+ cards, distinct mechanics, and multiple viable archetypes. No character is unplayable. All five can clear Ascension 20 in experienced hands. The rankings reflect consistency, not capability, the difference between "can win A20" (all of them) and "will win A20" (some more than others).

One important caveat: this tier list is for solo play. Co-op reshapes every character's value because support abilities and tank/DPS roles change the calculus entirely. Co-op has its own progression track and its own meta conversation.

Which Slay the Spire 2 characters are S-tier?

Ironclad and Necrobinder are the S-tier characters in Slay the Spire 2 as of patch v0.101.0. Ironclad brings four viable archetypes and the highest starting HP, making him the most adaptable character in the roster. Necrobinder's Doom mechanic bypasses traditional damage math entirely, turning threshold kills into a core strategy.

Ironclad

The king returns, and he's actually better in STS2 than he was in STS1. Four viable archetypes, Strength, Exhaust, Barricade Block, and Self-Damage/Rupture, give Ironclad more paths through any given run than any other character. 80 starting HP is still the highest. Burning Blood still heals post-combat. The fundamentals that made Ironclad the best learning character in STS1 are intact, but the card pool has expanded to include enough new options that Ironclad's ceiling rose alongside his floor.

Kamigame.jp rates Ironclad S-tier with a perfect 5/5 Strike axis score. Reddit and Steam discussions consistently place him at or near the top. The reason is straightforward: Ironclad rarely has dead runs. If Strength sources appear, take them. If Corruption shows up, pivot to Exhaust. If Barricade arrives early, go Block. If Rupture appears, build Self-Damage. This four-way flexibility means Ironclad can adapt to almost any card offering sequence, and in a roguelike, adaptability is the most valuable trait a character can have.

Necrobinder

The surprise of STS2. Necrobinder is an entirely new character with a mechanic that nobody expected to work as well as it does. Doom teaches execution thresholds, you mark enemies with Doom and they die when conditions are met, regardless of remaining HP. Souls teach resource management, a secondary resource system that sits alongside energy and provides additional plays.

Necrobinder is the first character in any Slay the Spire game to make "enemies die at a HP threshold" into a core mechanic rather than a niche card effect. The result is a character that can bypass the normal damage calculation entirely. Instead of dealing 200 damage to kill a 200-HP enemy, Necrobinder deals 100 damage, applies Doom, and the enemy dies anyway. This fundamentally changes the relationship between damage and defense, you need less total damage output, which frees up deck space for defensive and utility cards.

The learning curve is steep. Doom timing, Soul cycling, and understanding which enemies to mark versus which to fight traditionally requires genuine game knowledge. But once it clicks, Necrobinder feels like cheating. The character's Ascension 20 win rate is climbing fast as the community figures out the optimization path.

Which Slay the Spire 2 characters are A-tier?

Silent, Defect, and Regent sit in A-tier for Slay the Spire 2's Early Access period. Silent's Poison and Shiv archetypes remain strong but face stiffer competition. Defect offers the highest ceiling runs through orb synergies. Regent is the weakest of the five but steadily improving, with his Forge mechanic gaining viability through patches.

Silent

Silent's transition to STS2 has been rocky. Key cards were removed in v0.100.0 (Prepared, Borrowed Time) and then restored in v0.101.0, which whiplashed the community's evaluation. In the current patch, Silent is solid, her classic archetypes (Poison, Shivs, discard loops) are all viable, and the deeper card pool from STS2 gives her even more options than she had in the original.

The reason Silent dropped from S to A relative to STS1 is that the newcomers raised the bar. Necrobinder's Doom mechanic is more powerful than Poison in most situations (threshold kills versus damage-over-time kills), and Ironclad's four archetypes provide more flexibility than Silent's three. Silent is still the deepest deckbuilder in the roster. She's just not the deepest by as wide a margin as she was before.

Wraith Form remains one of the best cards in the game. Some things don't change.

Defect

Orbs return with refinements. The core system, Lightning, Frost, Dark, Plasma, is intact, with new cards and relics that provide more ways to interact with orb management. Echo Form is still ridiculous. Biased Cognition is still the card that scares new players and excites experienced ones.

Defect's problem in STS2 is the same as in STS1: polarization. Good Defect runs are among the best runs any character can produce. Bad Defect runs are among the worst. The character hasn't found a way to raise its floor, which means the average Defect run is less reliable than the average Ironclad or Necrobinder run. If you're tracking win rates across many runs, Defect's averages drag behind the S-tier characters.

That said, the community's love for Defect runs deep. The character offers a puzzle-box experience that no other character matches. Solving a Defect run feels like solving a mechanical puzzle. Solving an Ironclad run feels like pressing the gas. Both are valid. One is more consistent.

Regent

The Regent is the community's most-debated character, and the current consensus is "underperforming but improving." The Forge mechanic, building up a powerful sword throughout battle, lacks consistency and damage output to compete with the straightforward scaling other characters offer. Many of Regent's intended builds (minion summoning, colorless card generation) don't have strong enough payoffs yet. Several of his Rare cards are underwhelming, bloating the pool with options you don't want to see.

The v0.101.0 buff helped significantly. Regent went from "actively bad" to "viable but outclassed." The character can clear A20, experienced players have proven it repeatedly, but the path to get there requires more specific card offerings and more favorable RNG than any other character.

Our prediction: Regent will climb. The character's design space has the most room for improvement through future patches, and MegaCrit has shown willingness to buff underperformers. A Regent re-evaluation in six months might land him in A-tier. Right now, he's the weakest of five viable characters, which in STS2's tight roster is less damning than it sounds.

How do returning characters compare between STS1 and STS2?

Ironclad is stronger in STS2 thanks to an expanded card pool and additional archetypes. Silent is comparable but less dominant because newcomers raised the bar. Defect plays almost identically, retaining the same polarized highs and lows. Necrobinder and Regent are entirely new characters with no STS1 equivalents.

If you played STS1 and you're wondering how the returning characters changed:

Necrobinder and Regent are genuinely new experiences with no STS1 equivalent. Necrobinder's Doom is unlike anything in the original. Regent's Forge is ambitious but underbaked. Both are worth playing for the novelty alone, regardless of tier placement.

The Actual Takeaway

The best characters in Slay the Spire 2 are those with the most viable archetypes, because flexibility reduces the impact of bad RNG. Ironclad and Necrobinder lead for that reason. All five characters can clear Ascension 20, so tier placement reflects consistency across many runs, not raw power ceiling.

STS2 is in Early Access. This tier list is a snapshot, not a monument. Patches will change the ordering. New cards will shift archetypes. The Regent will almost certainly improve. What won't change is the fundamental structure: characters with more viable archetypes rank higher because flexibility reduces the impact of RNG, and reducing the impact of RNG is how you win roguelikes consistently.

Ironclad has four archetypes. Necrobinder has a mechanic that bypasses traditional damage math. Silent has the deepest card pool. Defect has the highest ceiling. Regent has the most room to grow. Five characters, five experiences, all viable, all worth your time.

The meta is young. Enjoy it before it calcifies.
