Slay the Spire 2 Hidden Gem Guide: How Replay Works
Hidden Gem is one of the strongest Colorless cards in Slay the Spire 2 because it can massively increase the power of a single card in your deck. Instead of dealing damage or blocking directly, it upgrades another card by giving it Replay multiple times. When that card is played later, it triggers several times in the same turn.
The effect can turn even basic cards into powerful tools. When Hidden Gem lands on an already strong card, the result can completely swing a fight.
What Hidden Gem Does
Hidden Gem gives a random card in your Draw Pile Replay 2, causing that card to trigger three times when played.
Replay repeats the card automatically after it is used. This means the card activates multiple times without spending extra energy.
Base version
Cost 1 Energy
A random card in your Draw Pile gains Replay 2
Upgraded version
Replay increases to 3
With the upgrade, the chosen card will trigger four total times when played.
Why Hidden Gem Is So Powerful
Replay multiplies the effect of a card without increasing its energy cost. That makes Hidden Gem extremely strong when it lands on a high impact card.
Even basic cards become much stronger with multiple triggers.
Possible outcomes include
Multiple attacks triggering in one play
Repeated block generation
Skills activating several times
When the effect hits a powerful ability, the results can carry an entire fight.
Good Targets For Replay
Hidden Gem selects a random card from your Draw Pile, so you cannot choose the exact target. Still, certain decks benefit more because they contain cards that scale well when repeated.
Cards that work well with Replay
High damage attacks
Strong defensive skills
Scaling abilities
If your deck contains several strong cards, the chance of hitting a great target increases.
Why Deck Quality Matters
Because Hidden Gem chooses randomly, the overall quality of your deck matters. If your deck contains mostly weak cards, the effect may land on something less exciting.
Decks that benefit most
Decks with strong attacks
Decks with powerful skill effects
Decks with fewer weak cards
Improving your deck quality increases the chance that Replay lands on something impactful.
Why The Upgrade Is Excellent
The upgrade adds one more Replay trigger, which increases the total number of activations.
Benefits of upgrading
Higher total damage potential
More block generation when used on skills
Greater value from powerful cards
Since the effect stacks with the strength of the target card, the upgrade can dramatically increase the payoff.
Final Blurb
Hidden Gem is a Colorless card that can turn a single card in your deck into a powerhouse. By granting Replay, it allows that card to trigger multiple times during a single play.
Because the target is random, the card rewards decks filled with strong abilities. When it lands on a powerful card, the effect can quickly take over a fight.
