1. Quick Answer: All Slay the Spire 2 Classes Explained

If you are trying to decide which character to pick for your next run (or your next Co-Op lobby), here is a quick overview of every class:

2. The Ironclad: Strength & Exhaust Builds

The Ironclad remains the most forgiving class for beginners due to his starting relic, Burning Blood, which heals 6 HP at the end of every combat.

• The Heavy Strength Build: Focus on cards like Demon Form and Limit Break. Once your Strength reaches double digits, multi-hit cards will instantly delete Act Bosses.
• The Exhaust/Corruption Build: A more advanced playstyle. By using Corruption to make all your Skill cards cost 0 Energy (but exhaust when played), you can cycle through your entire deck in a single turn.

3. The Silent: Poison, Shivs & The New ‘Sly’ Mechanic

The Silent requires careful energy management and a deep understanding of card draw. Mega Crit has heavily updated her kit for the sequel, introducing the brand-new ‘Sly’ keyword. Cards with the Sly keyword are automatically played for free when they are discarded from your hand.

• The Sly Discard Engine: Draft cards like Acrobatics or Calculated Gamble to discard your hand, triggering your Sly cards to deal massive damage and generate block without spending any Energy.
• The Poison Catalyst Build: Apply poison safely, then play Catalyst to double or triple the poison stacks. The enemy will simply melt away during their own turn.

4. The Defect: Orb & Focus Builds

The Defect’s gameplay loop revolves around his unique Orb slots. By channeling Orbs and increasing his “Focus” stat, he creates a passive engine that wins the game automatically.

• The Frost/Focus Turtle Build: Draft Glacier and Cold Snap to fill your slots with Frost Orbs. Use Defragment to increase your Focus. You will passively generate huge amounts of Block every turn.
• The Dark Orb Nuke Build: Channel a single Dark Orb and let it passively grow in damage over multiple turns. Once it reaches 100+ damage, use Multicast or Dualcast to evoke it, one-shotting the Act Boss.

5. The Necrobinder: Graveyard & Blood Magic

The first of the brand-new Godot-engine classes. The Necrobinder (a wandering lich) is a high-risk, high-reward character that redefines how you manage your health and discard pile.

• The Minion Swarm Build: The Necrobinder can physically summon her trusty left hand, Osty, onto the battlefield. Minions have their own HP pools and can intercept incoming attacks.
• The Blood Magic/Graveyard Build: Expend your own HP to play wildly overpowered spells for 0 Energy. Then, utilize mechanics that retrieve specific, high-damage cards directly from your Graveyard (formerly the Exhaust pile) to loop them infinitely.

6. The Regent: Stars, Minions & Forge Mechanics

The Regent introduces completely new mechanics: a persistent secondary resource called Stars (which carries over between turns without capping) and the Forge keyword.

• The Sovereign Blade Build: The Regent holds a signature colorless weapon card (The Sovereign Blade) that Retains in his hand. Every time you play a card with the Forge keyword, the Sovereign Blade’s damage increases. Build it up until you are ready to deliver a perfect, lethal blow.
• The Minion Sacrifice Build: Play cards like Guards to transform the cards in your hand into disposable Minions. You can sacrifice these minions for massive burst block or damage.

7. Best 4-Player Co-Op Class Combinations

If you are diving into the new Co-Op mode, team synergy is everything. Here are the top-rated combinations to dominate the Spire:
