Slay the Spire 2 Poison: What It Does

Poison is one of the main damage over time mechanics in Slay the Spire 2. Instead of dealing all your damage with attacks, Poison builds slowly drain enemy health while you focus on defense and setup.

What Poison Does In Slay the Spire 2

Poison is a debuff that damages enemies at the start of their turn, then decreases by 1 each turn.

When an enemy has Poison applied to them, the game checks the stack count at the start of their turn. The enemy takes damage equal to the Poison amount, and the stack then drops by one.

Example:

• Enemy has 6 Poison

• Start of turn, enemy takes 6 damage

• Poison drops to 5

Next turn the enemy takes 5 damage, then the Poison drops again.

How Poison Damage Works

Poison damage behaves differently from normal attacks.

• Poison stacks when applied multiple times

• Poison damage triggers automatically each turn

• Poison damage ignores enemy Block

• Poison slowly decreases every turn

Because it ignores Block, Poison can deal damage even when enemies are heavily defending.

Poison Decks In Slay the Spire 2

Poison decks focus on building large Poison stacks and letting the damage tick down over time.

Instead of trying to burst enemies quickly, these decks usually apply Poison early and then spend the rest of the fight defending while the damage builds.

Cards that apply Poison can stack together, which allows the damage to grow very quickly during longer fights.

Examples of Poison cards include:

• Poisoned Stab

• Deadly Poison

• Noxious Fumes

• Outbreak

These cards allow players to apply Poison to single targets or spread it across multiple enemies.

When Poison Is Strong

Poison becomes extremely strong in longer fights.

Bosses and elite enemies often survive many turns, which allows Poison stacks to build up into very large damage numbers. Because the damage happens automatically every turn, you can spend your energy blocking while the enemy slowly loses health.

When Poison Is Weaker

Poison is less effective in very short fights.

If enemies die quickly, the stacks do not have enough time to build up. In those situations direct attack damage is often faster.

Because of this, Poison decks usually perform best once the run reaches tougher enemies and bosses.

Final Blurb

Poison in Slay the Spire 2 is a stacking damage over time debuff that triggers at the start of an enemy’s turn. Each stack deals damage equal to its value and then drops by one. Poison decks focus on applying large stacks early and letting the damage build while you defend, making it one of the strongest strategies in longer fights.
