Endfield 1.0 Pity & Spark Calculator. Precise odds using a DP-based math engine.

"Stop guessing. Start calculating with mathematical precision." Most gacha calculators rely on Monte Carlo simulations—random trials that only give you an approximation. MirrorLab is different. We use DP-based state space analysis to provide the exact mathematical probability distribution for your pulls. ■ Day-One Support: Arknights: Endfield Optimized for the complex mechanics of Arknights: Endfield 1.0. Chartered Headhunting: Full implementation of the 120-pull Featured Guarantee (Spark). Arsenal Issue: Accurate modeling of the 80-pull guarantee and the 100/180/260... repeating mileage system. Hybrid Efficiency: Calculate how many Arsenal Tickets you’ll gain from character banners to plan your next 6-star weapon. ■ Why MirrorLab? Precision DP Engine: Forget the variance of Monte Carlo. Our engine uses recursive logic to calculate exact probabilities for every possible outcome. Refund Factor: Factor in 'Certificates' from duplicate pulls to determine your actual cost-per-pull and re-investment efficiency. Architect's Report: Visualize "Worst-Case Scenarios" and "Efficiency Zones" to optimize your spending and avoid mindless pulling. ■ Two Analysis Modes [Basic Mode] Quick Check Enter base rates, pity counters, and costs. Instantly see the pulls required for 50% / 90% / 99% success. Cost conversion to real-world items (e.g., pizza slices) for better financial perspective. [Pro Mode] Deep Dive Customize and edit Soft Pity curves. Get exact Expected Values and Standard Deviations. View detailed probability distribution histograms. ■ Roadmap: Coming Soon Full support for the following titles is coming soon: Genshin Impact Goddess of Victory: NIKKE Honkai: Star Rail Wuthering Waves ■ Key Features Works Offline: No internet required for calculations. Privacy First: No login, no data collection, no unnecessary permissions. Dark/Light Theme: Minimalist 'Mirror' interface designed for focus. Save & Share: Save your custom presets for any banner or game. Calculate before you pull. MirrorLab is the smartest sandbox for your gacha strategy.
