The Kafra's Gamble
Test your luck before wasting Zeny in-game. Our simulator uses authentic success rates from the official servers.
The Ragnarok Zero Refine Simulator is a powerful tool for calculating your success rates when upgrading gear. Specifically tuned for Ragnarok Zero Global (data based on TWRo Zero), it supports refining with Elunium, Oridecon, and the newer Zelunium and Shadowdecon ores. Our simulator includes the unique Blessed Blacksmith Ore (BSB) pity system, allowing you to run Monte Carlo simulations to estimate the total cost and material requirements for reaching +10, +12, or even +20. Don't leave your refines to chance—calculate your risks and optimize your zeny spending.
