How the estimate works
Use your own server rates
Metin2 Dragon Stone Alchemy has multiple progression layers: class, clarity, and level. The simulator lets you set success rates yourself because private servers and official servers may differ. The output is an expected-value estimate, not a guarantee.
Use it to compare whether pushing clarity, class, or level is the bigger material sink. For long-term planning, enter your daily Cor Draconis farming capacity and number of characters to estimate the time cost.
