STS2 Reward Card Helper FAQ
Quick answers about how this reward pick tool works.
What does the STS2 Reward Card Helper do?
This tool compares reward card options against your current Slay the Spire 2 deck, relics, character, and act to recommend the strongest pick.
Does it look at my current deck?
Yes. The helper scores your deck state first, then checks which reward card best patches weaknesses or strengthens your existing plan.
Does the recommendation change by act?
Yes. Act 1 values frontloaded damage more heavily, while later acts give more weight to scaling, consistency, and survivability.
Can I compare more than three reward cards?
Yes. You can add extra reward slots if you want to compare more than the standard three options.
