StS2 Winrate Preview
A Slay the Spire 2 map overlay that shows a combat-risk band — Safe / Caution / Danger — with a win-rate % and combat-quality % for the upcoming Monster / Elite / current-act Boss, before you pick a map node.
The estimate isn't a heuristic — it simulates the real STS2 combat engine in a separate headless helper process, using your current deck, relics, potions and HP. It is read-only and never touches your game state.
Features
-
[]A risk band per upcoming category (Monster / Elite / current-act Boss) on the map screen.[/]
[]Win-rate % + combat-quality % (HP you'd keep on a win), side by side.[/]
[]Real combat-engine simulation via a pooled headless helper — not a static formula.[/]
[]Aggregates over the whole act's encounter pool, so the band stays stable as you progress (only your deck / HP change it).[/]
[]Optional ModConfig settings — adjust the simulation trials per category (Monster / Elite / Boss, 1–10) in-game; more Boss trials = a steadier boss band. Without ModConfig the defaults apply.[/]
[]Draggable, dismissible panel; auto-hides whenever another screen (your deck / relic / potion view, pause, settings) is layered over the map.[/]
[]16 languages. Hover the panel for a short legend of the two numbers.[/]
How it works
-
[]A headless helper (Sts2CombatCore, downloaded separately — see Install) runs the actual game combat engine out-of-process.[/]
[]When you open the map, the mod sends your current deck / relics / potions / HP to a pool of helper processes, which simulate each upcoming encounter to a win/loss.[/]
[]The band appears within ~1s per fight. Bigger machine → more helpers → faster refresh.[/]
Install
[]Have an STS2 mod loader set up.[/]
[]Extract this mod archive into your game's mods folder.[/]
[*]Download the helper (~42 MB, required — it runs the real combat engine and is hosted on GitHub due to its size) and extract it into the same mods folder. Pick the build matching your gam
