Slay the Spire Wiki

The Champ is one of the three bosses encountered at the end of Act 2.


Phase 1[]

Always uses Taunt every 4 turns. On all other turns, has:

  • 15% chance to Defensive Stance
  • 15% chance to Gloat
  • 25% chance to Face Slap
  • 45% chance to Heavy Slash

Moves cannot be used twice in a row: If the previous move would be repeated, the move that comes after it in the list above is selected instead. For example, if the previous move was Gloat, there is now a 0% chance of Gloat and a 40% chance of Face Slap with all the other probabilities unchanged.

If Heavy Slash is used, its probability chance is added to Face Slap instead of Defensive Stance.

On Ascension Ascension Icon.png19+, he will use Defensive Stance instead of Gloat. Defensive Stance can be cast at most twice per battle and subsequent casts are instead Gloats, regardless of ascension.

When HP drops below 50%, he will use Anger next turn and enter Phase 2.

Phase 2[]

After using Anger, will use Execute immediately.

For the next two turns, selects random moves (same exact behavior as in Phase 1), then Executes again. Repeats this pattern (2 random moves, then Execute).

Once the Champ uses his Phase 2 attacks, his strength will be very high, making his attacks do significantly more damage. Combined with the Icon Frail.png Frail and Icon Vulnerable.png Vulnerable debuffs, the fight can quickly become very dangerous. Execute is a deadly attack; it can end up dealing damage in the twenties 2 times.

Generally, you want to spend the first half of the fight setting up, and then you want to very quickly kill the Champ once his HP drops below half.

Taunt is used on turn 4. Both Anger and Execute (from Phase 2) will override Taunt, letting you avoid the weak if you get his health below half on turns 3 or 4. If you cannot burst this quickly (most decks cannot), avoid getting him angry on turns 5 and 6, as the weak effect makes it difficult for you burst properly through Phase 2, and likely means you will eat another Execute.
