Slay the Spire 2 Triple Reward Mod v4.0

                    
Building a focused deck in Slay the Spire 2 should feel rewarding, but duplicate cards quickly become dead weight. The STS2 Triple Reward mod flips that entirely by turning three matching cards into something genuinely powerful. Collect three identical eligible cards and they automatically fuse into one upgraded copy with a Replay bonus, plus a free random card from the next rarity tier as a reward. Consequently, duplicates stop being a problem and start becoming a strategy.
What’s Included

Auto-Fusion: Three matching eligible cards in your deck automatically merge into one.
Replay Bonus: The fused card gains at least Replay 1 on merge.
Rarity Upgrade Reward: Receive a random card from the next higher rarity tier after each fusion.
Lightweight implementation compatible with most other mods and requires no additional frameworks.

Why You Need This Mod
Duplicate cards in Slay the Spire 2 dilute your draw and slow down tight builds. Furthermore, the standard reward system gives you no way to convert that redundancy into something useful. This mod introduces a satisfying deck-thinning loop that actively rewards commitment to a card strategy. Moreover, the rarity upgrade reward means every triple fusion also pushes your deck forward, making focused runs feel progressively stronger rather than stagnant.
