How Many Characters Are in Slay the Spire 2 Early Access?
There are five playable characters in Slay the Spire 2 Early Access. Two are returning from the original game (Ironclad and Silent), two are brand new (Regent and Necrobinder), and the Defect also makes a return. The Watcher from StS1 is not in the Early Access build.
| Character | Status | Starting HP | Starting Relic | Playstyle | Difficulty |
|---|---|---|---|---|---|
| The Ironclad | Returning | 80 | Burning Blood | Strength, exhaust, block | Easy |
| The Silent | Returning | 70 | Ring of the Snake | Poison, shivs, discard/Sly | Medium |
| The Regent | New | 75 | Divine Right | Spells, Stars resource, Forge | Medium |
| The Necrobinder | New | 66 | Bound Phylactery | Doom, Graveyard, Osty companion | Hard |
| The Defect | Returning | 75 | Cracked Core | Orbs, channels, lightning | Medium–Hard |
The Ironclad
The Ironclad is a melee warrior built around brute force. He has the highest starting HP in the game, a self-healing relic and a deck that immediately teaches the core StS2 combat loop. If you are new to the game or new to deck-builders, start here.
Ironclad Stats and Starting Relic
- Base HP: 80 (drops to 64 at Ascension 2 and above)
- Starting Relic — Burning Blood: Heal 6 HP at the end of every combat. This passive sustain is the reason the Ironclad forgives early mistakes better than any other character. Small miscalculations in block management are automatically undone between encounters.
Ironclad Starter Deck
The Ironclad begins every run with 10 cards: five Strikes, four Defends and one Bash. Bash deals 10 damage and applies 2 Vulnerable, making enemies take 50% more damage from attacks — a built-in setup card that works with every archetype from the very first combat.
Ironclad Best Builds and Archetypes
| Archetype | Core Mechanic | Key Cards | When to Pick It |
|---|---|---|---|
| Strength Build | Stack permanent Strength buffs; multi-hit attacks scale exponentially | Inflame (+3 Str in StS2), Demon Form, Twin Strikes, Whirlwind, Fiend Fire | Best default option — pick up any Inflame |
| Exhaust Build | Use Corruption to make all Skills zero-cost and exhausting; trigger Dark Embrace and Feel No Pain | Corruption, Dark Embrace, Feel No Pain, Dead Branch | When you hit a Corruption early in Act 1 |
| Block/Body Slam | Accumulate massive Block, then convert it directly to damage | Body Slam, Juggernaut, Entrench, Shrug It Off | Good vs high-damage bosses |
| Self-Damage Synergy | Intentionally lose HP to trigger bonus effects (new in StS2) | Rupture, Bloodletting, Combust, Brutality | High risk — powerful but demands tight HP tracking |
Inflame was buffed in Slay the Spire 2 — it now gives +3 Strength instead of +2. Strength scales every attack simultaneously, so Whirlwind and multi-hit cards hit exponentially harder the earlier you stack it.
Ironclad Strengths and Weaknesses
- Strengths: Highest HP pool of any character; Burning Blood heals without needing rest sites; multiple viable archetypes; linear Strength build is easy to pilot; Bash gives instant synergy from turn one.
- Weaknesses: Lower skill ceiling than Silent or Defect; can struggle against multi-enemy encounters without AoE tools early; Exhaust build requires precise card sequencing or it collapses.
Beginner difficulty rating: Easy. The Ironclad is the universally recommended first character — tanky, forgiving and straightforward to pilot.
The Silent
The Silent is a rogue-type character who wins through card draw, debuffs and combo chains rather than raw HP. She starts with the largest deck in the game and the best card-draw relic. Mastering her is how you unlock the highest skill ceiling in StS2.
Silent Stats and Starting Relic
- Base HP: 70 (drops to 56 at Ascension 2 and above)
- Starting Relic — Ring of the Snake: Draw 2 additional cards at the start of every combat. This gives the Silent a consistent card-draw advantage throughout the entire run, enabling faster combo assembly and thinner deck cycling.
Silent Starter Deck
The Silent starts with 12 cards — the largest starting deck in the game: five Strikes, five Defends, one Neutralize (apply 1 Weak) and one Survivor. Survivor is key: it is a Sly card (see below), and it introduces the discard-based archetype from your very first combat.
The Sly Keyword (New in Slay the Spire 2)
Sly is a Silent-exclusive mechanic introduced in StS2. Cards with the Sly keyword play for free automatically when they are discarded from your hand during your turn. Survivor is a Sly card, so if you discard it while cycling your hand, it triggers without costing Energy. This creates a discard-and-replay loop that, when scaled up with the right relics and cards, becomes one of the most powerful combo engines in the game.
Silent Best Builds and Archetypes
| Archetype | Core Mechanic | Key Cards | When to Pick It |
|---|---|---|---|
| Poison Build | Stack Poison on enemies; each Poison tick reduces stacks by 1 and deals that much damage | Deadly Poison, Bouncing Flask, Accelerant, Catalyst, Poison Stab | Slow burn — requires 2–3 turns to ramp; dominant in long fights and Act 3 |
| Shiv/Infinite Build | Generate zero-cost Shiv cards, spam them to trigger relic bonuses (Shuriken, Kunai, Fan) | Blade Dance, Infinite Blades, Accuracy, Storm of Steel, Finisher | When you hit Accuracy early — doubles Shiv damage |
| Sly/Discard Build | Use discard effects to trigger Sly cards for free; combo chain each turn | Flick-Flack, Acrobatics, Tactician, Ricochet, Master Planner, Prepared | Best late-game ceiling — hardest to assemble; high payoff |
Silent Strengths and Weaknesses
- Strengths: Best sustained card draw of all five characters; Ring of the Snake makes early combats faster; Sly mechanic creates uniquely powerful free-play loops; three genuinely different viable archetypes; excellent late-game scaling in all three builds.
- Weaknesses: No healing whatsoever — every mistake costs more; weaker early damage than Ironclad before combo pieces arrive; multi-enemy encounters are harder without AoE; Sly/discard build requires thin deck discipline that is non-intuitive for new players.
Beginner difficulty rating: Intermediate. The Silent is the best second character once you understand how energy management and deck thinning work. Do not start here if you have never played a deck-builder before.
The Regent (New Character)
The Regent is one of two brand-new characters in StS2 Early Access. An arrogant alien who floats in a chair and fires cosmic spells, the Regent is a spell-caster archetype built around a secondary resource called Stars.
- Base HP: 75
- Starting Relic — Divine Right: Generates 3 Stars at the start of each combat
- Stars mechanic: A secondary resource (max 24) generated by cards and spent on powerful spell effects. The Regent is the only character with a persistent secondary resource that carries between turns.
- Forge mechanic: Upgrades the Sovereign Blade mid-run, progressively adding damage to it as you progress. Your primary weapon literally improves as you play.
The Regent currently sits near the top of community tier lists for damage ceiling, but requires building the Stars engine before anything pays off. Difficulty: Medium–Hard.
The Necrobinder (New Character)
The Necrobinder is the most mechanically complex character in StS2 Early Access. A necromancer with the lowest HP in the game, she fights alongside a large skeleton hand companion called Osty.
- Base HP: 66 (lowest of all five characters)
- Starting Relic — Bound Phylactery
- Osty companion: A skeletal hand with its own HP bar that fights enemies independently and intercepts incoming damage — effectively a second health pool. Managing Osty’s survivability is a core part of every Necrobinder run.
- Doom mechanic: Stack Doom on an enemy. When Doom stacks reach or exceed the enemy’s remaining HP, the enemy dies after its next turn — an execution ability unique to this class.
- Graveyard mechanic: Exhausted cards become retrievable from a second pile called the Graveyard. Unlike other characters where Exhaust is a permanent cost, the Necrobinder treats the exhaust pile as a secondary hand she can pull from.
- Blood Magic: Spend HP to activate powerful effects — high-risk on a 66 HP character.
The Necrobinder rewards experienced players who want to manage three parallel systems simultaneously. Difficulty: Hard. Not recommended for new players.
The Defect (Returning Character)
The Defect returns from StS1 as a robotic character who channels elemental orbs — Lightning, Frost, Dark and the new Glass orb — to generate passive damage, block and focus effects every turn.
- Base HP: 75
- Starting Relic — Cracked Core: Generates a Lightning orb at the start of every combat
- New in StS2 — Glass Orb: A new orb type that channels AoE damage across all enemies, decreasing each turn, and Evokes for double its current value. Gives the Defect better multi-enemy tools than it had in StS1.
- Playstyle revolves around orb sequencing, Focus stacking and choosing when to Evoke vs. let orbs passively channel.
Difficulty: Medium–Hard. The Defect’s orb system has a steep learning curve but is highly satisfying once mastered.
Full Character Comparison Table
| Character | HP | Relic | Core Loop | Healing? | Best For | Avoid If |
|---|---|---|---|---|---|---|
| Ironclad | 80 | Burning Blood | Stack Strength, exhaust for value, convert block to damage | Yes (6 HP/combat) | New players, consistent runs | You want complex combos |
| Silent | 70 | Ring of the Snake | Draw fast, layer debuffs or combo discard chains | No | Intermediate players, highest ceiling | You hate fragile characters |
| Regent | 75 | Divine Right | Build Stars engine, cast high-value spells, upgrade blade | No | Players who like resource management | You want instant payoff |
| Necrobinder | 66 | Bound Phylactery | Manage Osty, stack Doom, exploit Graveyard | Conditional | Experienced players, unique mechanics | You are new to the game |
| Defect | 75 | Cracked Core | Channel orbs, stack Focus, choose when to Evoke | No | Players who like engine-building | You want direct damage |
Which Character Should You Pick First?
Start with the Ironclad. Here is why the community consensus is unanimous on this:
- 80 HP is the most forgiving starting health pool — you can take hits while learning.
- Burning Blood heals 6 HP every single combat, automatically undoing small mistakes.
- The Strength build is linear to execute: pick up Strength-giving cards, attack for big numbers. There are no secondary resources, no companion management and no discard timing.
- The starter deck’s Bash teaches the core Vulnerable mechanic in your very first fight.
- Even on failed runs, the Ironclad’s feedback loop is clear — you can see exactly where things went wrong.
Once you understand how Energy management, deck thinning and boss patterns work, move to the Silent to learn combo sequencing. Then try the Regent or Defect once you want a mechanical challenge.
How to Unlock All Characters
Characters unlock sequentially — you do not need to win or clear Act 1. Even selecting “Give Up” after loading into a run counts as a completed run for unlock purposes. All five characters can be unlocked in under 15 minutes.
- Ironclad — Available immediately from the start
- Silent — Complete one run as the Ironclad (win, lose or abandon)
- Regent — Complete one run as the Silent
- Necrobinder — Complete one run as the Regent
- Defect — Complete one run as the Necrobinder
If you want to experience all five characters before committing to one, just start five runs and immediately give up — the Epoch meta-progression system still awards rewards for short runs, so nothing is wasted.
Frequently Asked Questions
Is the Watcher in Slay the Spire 2?
No. The Watcher is not in Slay the Spire 2 Early Access. MegaCrit has not announced whether she will be added in a future update. The Necrobinder appears to fill the “experimental fourth character” slot in Early Access content.
Which Slay the Spire 2 character has the highest skill ceiling?
The Silent, closely followed by the Necrobinder. The Silent’s Sly/discard build requires precise hand management, deck thinning and Sly timing to execute correctly — but when it clicks, it is the most explosive archetype in the game. The Necrobinder has the most parallel systems to manage simultaneously.
Can you play all characters in co-op multiplayer?
Yes. Slay the Spire 2 supports co-op for up to four players. Each player runs an independent deck and HP pool, but you share the same map and can cross-contaminate status effects — for example, the Silent’s poison benefits when a teammate triggers it on an enemy.
Which character is best at higher Ascension levels?
The Silent and Regent tend to scale better at high Ascension due to their higher burst ceilings. The Ironclad’s healing advantage diminishes as Ascension HP penalties reduce starting health significantly. That said, experienced Ironclad pilots still reach Ascension 20 on Strength builds consistently.
Are new characters harder to unlock in Slay the Spire 2 vs StS1?
Significantly easier. In StS1, you needed to reach and defeat specific acts. In StS2, a single run of any length — including an abandoned run — counts toward the next unlock. The Epoch meta-progression system also provides rewards regardless of how far you get.
