Scale conversations without scaling your team

Hey everyone, I’ve been building a few Slay the Spire 2 tools recently and figured some of you might find them useful for planning runs and co-op. Damage Calculator Test card lines with Strength, Vulnerable, Block, Poison, etc. to see if a turn is actually lethal before you commit. https://slaythespire2.space/dama... Deck Builder Build and tweak your deck + relics outside of a run so you can theorycraft lines, check curve, and plan upgrades/routes without the in-game pressure. https://slaythespire2.space/deck... Co-op Synergy Builder Pick your team’s classes (2–4 players) and see which co-op cards and class combos synergize best, plus how your team scales as you add more players. Pairs well with a co-op guide that goes over class pairings and difficulty scaling. https://slaythespire2.space/co-o... If you try any of these during your runs (or with friends in co-op), I’d love to hear any feedback or weird edge cases you run into.
