Slay The Spire 2 Knife Trap Guide: How The Card Works
Knife Trap is a Silent rare skill in Slay the Spire 2 that unleashes every Shiv sitting in your Exhaust Pile. When you play it, the game automatically plays each exhausted Shiv against the target enemy. In the right deck this can create a huge burst of damage in a single turn. The more Shivs you exhaust during a fight, the stronger Knife Trap becomes.
What Knife Trap Does In Slay The Spire 2
Knife Trap costs 2 energy and targets a single enemy. When used, it plays every Shiv that currently exists in your Exhaust Pile. Each Shiv still deals its normal damage and counts as a played attack.
This means the card scales naturally during a fight. If several Shivs have already been exhausted, Knife Trap can suddenly fire off a large chain of attacks.
The upgraded version becomes even stronger. Knife Trap+ upgrades each Shiv before playing it, which increases the damage of the entire combo.
Why Shiv Decks Love Knife Trap
Knife Trap works best in decks that generate a lot of Shivs. Shiv cards are usually cheap and appear frequently in Silent builds.
During combat many Shivs get exhausted after being played. Knife Trap turns those exhausted cards into extra damage later in the fight.
Instead of losing those Shivs permanently, the card brings them back for one big finishing burst. It feels a bit like the deck suddenly remembered every knife it threw earlier.
How Knife Trap Damage Scales
The damage from Knife Trap depends entirely on how many Shivs are sitting in the Exhaust Pile.
If only a few Shivs are exhausted, the card does modest damage. If a Shiv heavy deck has filled the Exhaust Pile, Knife Trap can unleash a long chain of attacks.
This scaling makes the card stronger as fights go on. Boss encounters and elite battles are where Knife Trap tends to shine the most.
Tips For Using Knife Trap
Knife Trap becomes much stronger when your deck can create and exhaust many Shivs during combat.
A few simple habits can help maximize its damage.
Build around Shiv generating cards
Let Shivs accumulate in the Exhaust Pile before using Knife Trap
Save the card for elite or boss fights when possible
Upgrade Knife Trap early if your deck relies on Shivs
Use it as a burst finisher once enough Shivs are exhausted
Timing the card correctly often leads to the biggest damage turns.
Final Blurb
Knife Trap is one of the strongest payoff cards for Shiv focused Silent decks in Slay the Spire 2. By replaying every exhausted Shiv, it turns earlier attacks into a huge burst of damage later in the fight. If your deck creates a steady stream of Shivs, Knife Trap can quickly become one of the most dangerous cards in your run.
