Slay the Spire 2 Character Tier List: Best Characters Ranked for High Ascension

Tier List Overview

• S-Tier: Ironclad, Necrobinder — Highest win consistency at Ascension 15+. Multiple strong archetypes. Forgiving mechanics that tolerate imperfect play. Both have self-sustain (Burning Blood, Soul cycling) that reduces run-ending variance.
• A-Tier: Silent, Defect, Regent — Strong characters with clear win conditions. Slightly more dependent on specific card finds or build commitments. Silent and Defect carry over proven STS1 frameworks. Regent rose from B-tier to A-tier after v0.101.0 buffs to Falling Star and Parry.
• No B/C-Tier characters exist in the current meta. All five characters can clear Ascension 20. The gap between S and A tier is consistency, not capability.

S-Tier: Ironclad — The Consistent Powerhouse

• Strengths — Four viable archetypes (most of any character). 80 starting HP is the highest. Burning Blood enables aggressive pathing. Bash provides Vulnerability from the starting deck. Limit Break + Heavy Blade scaling has no damage ceiling. Dropkick infinite loop is still functional post-v0.100.0.
• Weaknesses — Draw power is limited compared to Silent or Necrobinder. No innate cycling mechanic. Strength builds need 2-3 acts to reach full power. Dead Branch removal weakened Exhaust builds compared to STS1.
• Best Archetypes — Strength Scaling (highest consistency): Inflame, Limit Break, Pummel Strike. Exhaust Engine: Corruption, Feel No Pain, Dark Embrace. Barricade Block: Barricade, Body Slam, Entrench. Self-Damage (new in STS2): Rupture, Combust, Hemokinesis.
• Why S-Tier — No bad matchups against any boss. Vulnerability from Bash is universally useful. Four archetypes mean you almost always find a viable path. Burning Blood reduces the cost of mistakes. The Ironclad is the only character that can win with a mediocre deck because Strength scaling carries suboptimal card pools.

S-Tier: Necrobinder — The Execution Machine

• Strengths — Doom bypasses HP totals (execute enemies below threshold). Souls provide free draws, solving hand quality issues. Three strong archetypes: Exhaust, Doom scaling, Minion/Osty. Osty (companion) absorbs damage and deals passive damage. Exhaust synergies thin the deck aggressively. Strongest boss-killing potential of any character.
• Weaknesses — Doom requires setup turns before it becomes lethal. Early Act 1 can be rough without immediate Doom payoffs. More complex to pilot than Ironclad — sequencing Souls and Exhaust correctly requires practice. Weaker against enemies with high HP thresholds until Doom stacks.
• Best Archetypes — Doom Scaling (highest ceiling): No Escape (exponential Doom), Dark Pact (exhaust cycling). Exhaust Engine: mirrors Ironclad exhaust but with Souls for draw. Minion Build: Osty + support cards for a two-pronged attack.
• Why S-Tier — Doom is the most powerful single mechanic in STS2. It turns boss fights from endurance tests into execution puzzles. Souls solve the universal problem of bad draws. The Necrobinder has the highest ceiling of any character and a floor that still clears content consistently. Kamigame and NamuWiki both rate the Necrobinder at or above Ironclad for experienced players.

A-Tier: Silent — The Proven Framework

• Strengths — Poison bypasses Block entirely (damage over time). Sly discard has the highest single-turn damage ceiling in the game. Shivs provide consistent chip damage and proc relic effects. Three distinct archetypes cover different strategies. v0.101.0 restored Prepared and Borrowed Time, improving consistency. Strong draw engine through Backflip, Acrobatics, and cycling.
• Weaknesses — Poison is slow against bosses with high HP scaling phases. Shivs fall off in Act 3 without scaling support. Sly builds require specific card combinations to reach their ceiling. No innate self-healing (unlike Ironclad's Burning Blood or Necrobinder's Osty). More dependent on good early card offers than S-tier characters.
• Best Archetypes — Poison: Deadly Poison, Catalyst (triple poison), Noxious Fumes (passive stacking). Sly/Discard: Sly-keyword cards auto-play when discarded, Calculated Gamble, Tactician. Shivs: Blade Dance, Cloak and Dagger, Accuracy (+damage per Shiv).
• Why A-Tier (Not S) — Two of three archetypes (Poison, Shivs) have known scaling ceilings against late-game bosses. Sly has no ceiling but requires lucky card finds. The Silent wins most runs but occasionally faces dead runs where no archetype comes together. The v0.101.0 Prepared/Borrowed Time restorations partially addressed this inconsistency.

A-Tier: Defect — The Rebuilt Engine

• Strengths — Orbs provide passive damage and utility every turn without card plays. Plasma Orbs solve energy problems, enabling expensive card plays. Claw archetype provides a reliable low-cost scaling path. Dark Orbs scale automatically over time, rewarding long fights. Strong AoE through Lightning Orbs. Cracked Core (starter relic) provides free Orb generation from turn 1.
• Weaknesses — Permanent Focus stacking is gone — cannot recreate STS1's infinite Focus builds. Dark Orb scaling is slow in short fights (Act 1 elites). Orb slots are limited, requiring management decisions. More dependent on understanding the new Orb economy than any other character's learning curve. Frost Orbs alone cannot sustain defense against high-damage bosses.
• Best Archetypes — Dark Orb Control: let Dark Orbs accumulate damage passively, channel new Orbs strategically. Claw Deck: Claw, Scrape, All for One, FTL, Beam Cell (0-cost scaling). Plasma Energy: use Plasma Orbs to fund expensive Powers and attacks.
• Why A-Tier (Not S) — The reworked Orb system has a learning curve that punishes players carrying STS1 habits. Dark Orbs are slow starters. The Defect has fewer viable archetypes (3) than Ironclad (4) and less raw power than Necrobinder's Doom. But once mastered, the Defect's passive Orb damage provides a unique advantage in long fights where other characters need to spend cards to deal damage.

A-Tier: Regent — The Rising Star (Post-v0.101.0)

• Strengths — Stars persist between turns, creating a resource management layer unique to the Regent. Seven Stars converts accumulated Stars into 49 AoE damage (7 Stars x 7 damage). Sovereign Blade (Retained weapon) provides consistent damage every turn. Forge archetype creates permanent upgrades mid-combat. v0.101.0 Falling Star buff improved Star generation. v0.101.0 Parry buff improved defensive consistency.
• Weaknesses — Stars and Forge dilute each other if pursued simultaneously — pick one. Star accumulation is still slower than Necrobinder's Doom or Ironclad's Strength. Sovereign Blade dependency can become a liability against enemies that strip Retained cards. Smallest community knowledge base (newest character, least explored). No community-proven infinite combos.
• Best Archetypes — Stars Burst: Big Bang (0-cost cycle), Alignment (Stars to Energy), Seven Stars (finisher). Focus Stars exclusively — do not mix with Forge. Forge Crafting: permanent mid-combat upgrades. Slower but more consistent than Stars. Sovereign Blade Midrange: use Retained Sovereign Blade as a reliable damage source, supplement with Stars or Forge.
• Why A-Tier (Not S) — The Regent was B-tier before v0.101.0. The Falling Star and Parry buffs elevated the character significantly, but the Regent still has the smallest proven archetype pool and the steepest learning curve. Community knowledge is months behind the other four characters. The Regent's ceiling may be S-tier once more tech is discovered, but current data places the character solidly at A.

v0.101.0 Meta Shift Analysis

• Regent Buffs — Falling Star now generates Stars more efficiently, addressing the core complaint that Star accumulation was too slow. Parry improvements give the Regent a real defensive option instead of relying entirely on Stars for both offense and defense. These two changes alone moved the Regent from B-tier to A-tier in community consensus.
• Silent Restorations — Prepared and Borrowed Time were removed in v0.100.0 and restored in v0.101.0. These cards are essential for the Sly/discard archetype. Their return improved the Silent's consistency and prevented the character from dropping to B-tier.
• Doormaker Rework — The Doormaker boss was changed from random mechanics to a 3-form phase rotation (damage/debuff/defense). This change benefits patient characters (Ironclad Strength stacking, Regent Star accumulation) and slightly hurts aggressive characters that preferred to race the old random Doormaker.
• Infinite Combo Return — v0.101.0 eased some of the anti-infinite measures from v0.100.0. The Dropkick Loop (Ironclad) is functional again. No confirmed infinite loops exist for Regent, but community research is ongoing.
• Map Generation Fix — Elites no longer appear on floor 6, and early monster density was reduced. This benefits all characters equally but disproportionately helps weaker Act 1 characters (Regent, Defect) who previously faced punishing early elites before their builds came online.

Solo vs Co-op Tier Differences

• Necrobinder: S-tier in Solo, S+-tier in Co-op — Doom scales independently of boss HP (execute threshold is percentage-based). Osty provides team utility. Souls draw benefits from longer fights. The Necrobinder is the single strongest co-op character.
• Ironclad: S-tier in Solo, A+-tier in Co-op — Bash's Vulnerability benefits all teammates' damage. Strength scaling is less impactful when boss HP is 2-3x higher and other players handle damage. The Ironclad shifts to a support/debuff role in larger groups.
• Silent: A-tier in Solo, A-tier in Co-op — Poison damage ignores Block, which scales well in co-op. Shivs trigger on-attack relics for teammates. Sly remains a solo-oriented archetype. Consistent but not dominant in either mode.
• Defect: A-tier in Solo, A-tier in Co-op — Orbs provide passive damage without consuming team actions. Lightning AoE clears adds. Frost Orbs can absorb damage for the team. Utility-focused but lacks the raw power to carry co-op fights.
• Regent: A-tier in Solo, B+-tier in Co-op — Stars are self-contained and do not benefit teammates. Sovereign Blade damage does not scale with team size. The Regent contributes the least to team synergies. In co-op, the Regent is the weakest pick unless the Stars build is fully online.

Beginner Recommendations

• First Character: Ironclad — Highest HP (80), post-combat healing, and intuitive Strength scaling. Bash teaches Vulnerability. Limit Break teaches multiplicative scaling. Burning Blood forgives mistakes. kamigame.jp recommends Ironclad for first victories.
• Second Character: Silent — Poison teaches damage-over-time strategy. Shivs teach multi-hit scaling. Backflip and Acrobatics teach draw management. Two well-documented archetypes from STS1 with extensive community guides.
• Third Character: Necrobinder — Doom teaches execution thresholds. Souls teach resource management. Exhaust teaches deck thinning. More complex than Ironclad/Silent but extremely rewarding once understood.
• Fourth Character: Defect — Orb management requires understanding a resource system unique to STS2. Players coming from STS1 must unlearn Focus stacking. Best approached after understanding the base game through other characters.
• Fifth Character: Regent — Most mechanically unique. Stars and Forge have no parallel in STS1 or other STS2 characters. Smallest community knowledge base. Play last to bring maximum game understanding to the steepest learning curve.
