About this calculator
A free Star Force calculator for MapleStory (GMS) with the new Enhancement Modes added in v269 — higher modes cost more mesos on 15★–21★ but boom less (Mode 4 can't boom at all). It runs Monte Carlo simulations of meso cost and boom count, supports a different mode and safeguard per star, and the Optimizer finds the plan with the best odds of hitting your target star for your meso budget and spares. All rates and costs are confirmed in-game; events, MVP discounts, and star catching are supported. The Fodder tab compares star force transfer strategies — enhancing a cheaper fodder item and transferring its stars onto the real one — against tapping the real item directly, and finds the cheapest transfer star.
