FS cost calculator

How it works?

It calculates the average probability and the cost of getting a certain amount of failstacks using +14 reblath armor (shoes). It suggests that if you get it to +15 then you drop it using a cleanse mechanic.

This formula calculates the silver cost and the amount of blackstones, where fs is a desirable amount of failstacks and p is a chance of a previous enchant.

Reblath enchant chance is taken from ingame data. You can alter the variables for your own need.

Things to remember

Data shows an average calculation. Your personal single experience may heavily vary, but on a log run the model should work fine.
