Now in your language. SpireSage is now fully localized in 8 new languages: Simplified Chinese, Traditional Chinese, Korean, Japanese, Russian, French, German and Spanish. Not just the menus: every card and relic, enemy patterns, strategy guides and expert notes are translated too. Ask Spiro AI a question in your language and it replies in the same one. Pick your language the moment you open the app, or change it anytime in Settings. Card, relic and character names stay in their original English, so they always match what is on your screen in Slay the Spire 2. Upgraded cards, complete at last: card detail pages now show the upgraded text and cost for 400+ cards, so you can weigh base versus upgrade in a single glance. A Go Pro screen that fits the moment: it adapts to what you are doing, and the Founders Pass now shows a live counter. Only 100 lifetime spots exist, and you can see how many are left. Fewer interruptions: upgrade and review prompts now wait until the app has actually helped you, so nothing breaks your run. Plus a more reliable Pro experience and a fresh round of polish.
