Slay the Spire 2: How to Unlock All Characters Fast

The locked roster in Slay the Spire 2 looks like a progression wall that wants multiple full clears. It isn’t. On a fresh save, Ironclad starts unlocked, and the rest of the cast opens in a fixed chain just by playing a run with the previous character — win or lose. The fastest way to all five is four very short runs, not four Act 3 victories.

The short version

• Unlock order is fixed: Ironclad → Silent → Regent → Necrobinder → Defect.
• Ironclad is unlocked from the start; each other character opens after you play a run as the one before it.
• You do not need to win. A failed or abandoned run counts — selecting Give Up from the in-run menu registers your participation.
• Early Access has exactly five core characters, with no hidden boss kill or difficulty gate for basic unlocks.
• So the whole roster opens with four quick runs: start as each newly unlocked class, then Give Up.

The full unlock chain

• Ironclad — unlocked by default at the start of the game.
• Silent — unlocks after you play a run as Ironclad.
• Regent — unlocks after you play a run as Silent.
• Necrobinder — unlocks after you play a run as Regent.
• Defect — unlocks after you play a run as Necrobinder.

The chain is sequential and cannot be skipped. You can’t open Regent straight from Ironclad, and you can’t jump ahead to Defect early. Each character you unlock is the key to the next one.

Fastest way to unlock the full roster

Speed-run the whole thing with abandoned runs. Because a failed run counts the same as a win for unlock purposes, you never have to climb. Use a standard solo run for each step — there’s no reason to add variables.

Step 1: Play a run as Ironclad

From a fresh save, pick Ironclad and start a run. Once you’re actually inside the run (map loaded, first room available), open the menu and choose Give Up. That ends the run as a loss — and unlocks Silent.

Step 2: Play a run as Silent

Select Silent, start a run, and Give Up the same way. That unlocks Regent. You don’t need to prove anything — unless you actually want to learn Silent’s deck and pacing while you’re here.

Step 3: Play a run as Regent

Repeat with Regent: start the run cleanly, then forfeit from the in-run menu. That unlocks Necrobinder.

Step 4: Play a run as Necrobinder

Do it one more time with Necrobinder. End the run and Defect unlocks. Because Ironclad is already available, that’s the full five-character roster in four short runs total.

Each character, briefly

Ironclad is the starting character — nothing to unlock. He’s the first link in the chain, so his only job for progression is to open Silent.

Silent opens after a run as Ironclad, win or loss. If she doesn’t appear, make sure you ended a real run rather than backing out at character select.

Regent opens after a run as Silent. The roster screen makes it feel like there’s a tougher requirement — there isn’t. Start the run, Give Up, move on.

Necrobinder opens after a run as Regent. On the speed method this is your third short run after Ironclad. You can’t reach Defect without touching Necrobinder first.

Defect opens after a run as Necrobinder — the final step. Once Defect is available you have the complete Early Access lineup of five.

Common mistakes

• Trying to win every unlock run. You don’t need an Act clear. Forcing full climbs just to access a class only burns time.
• Backing out too early. Get fully inside the run before you Give Up — canceling at character select doesn’t register the run.
• Following the chain out of order. It’s strictly sequential: you can’t unlock Regent from Ironclad or jump straight to Defect.
• Assuming there’s a hidden boss or difficulty gate. There isn’t one for these five core characters — only sequential run participation.
• Confusing roster unlocks with other progression. Card pools, rewards, and achievements are separate systems and don’t change the five-character chain.

If a character won’t unlock

Check two things first: that you ended from inside a fully started run (not the character-select screen), and that you played the chain in order. If both are right and the next character still isn’t there, restart the game so the unlock registers, then try one more clean start-and-Give-Up run with the required class.

Worth noting: Slay the Spire 2 has been in Early Access since March 5, 2026, so a future patch could adjust how unlocks work. Standard solo runs with a clean start-and-forfeit remain the safest method.

Practical takeaway

Open the whole roster first, then learn the deck you actually want. Do four short runs — Ironclad, Silent, Regent, Necrobinder — hitting Give Up in each, and all five characters are yours. From there, your real progression begins: Ascension unlocks after your first win with a character, so see all Ascension levels explained (A1–A10) next. And while you’re still finding your footing, healing efficiently matters more than any unlock trick.
