Welcome to SpirePlanner 2, the definitive proactive companion for deck-builders and roguelike strategists! Beyond mere guides, SpirePlanner 2 models entire runs of Slay the Spire 2, simulating deck synergies, event choices, relic combinations, and predicting possible enemies and loot. Strategize, experiment, and compare outcomes in a fully interactive environment — perfect for theorists, speedrunners, content creators, and meta-analysts.
(Year: 2026 Edition — Multilingual, Always-Evolving, and Community-Powered)
SpirePlanner 2 lets you chart complete hypothetical Spire ascensions. Visualize branching possibilities, make smarter event choices, and calculate win probabilities by simulating encounters, relic drops, and path routes. Integrated with cutting-edge language models (OpenAI GPT and Claude), it even lets you ask “What If?” question and receive step-by-step analyses, almost like having a co-op strategist by your side.
- Simulated Runs — Plan and visualize your path from floor 1 to heart, considering deck builds, shops, transformation, hoards, and more.
- Deck Synergy Analyzer — Input your deck, and instantly see potential combos and deadly pitfalls.
- Enemy Intent Predictor — Based on known attack rotations and randomization rules, anticipate the deadliest turns.
- OpenAI & Claude Integration — Get tactical advice, probability breakdowns, and strategic recommendations, anytime.
