Class roll calculator
Work out your real chance of rolling a class, and what those rolls cost.
Calculator
Rolling a class costs 40 diamonds and the outcome is independent every time — there is no pity counter. Pick what you are chasing and how many rolls you can afford, and this gives the actual probability rather than the average, which is the number people misread. Chances come from our classes table.
Chance of getting it
Each roll is independent, so the chance of still not having it after n rolls is (1 − p)ⁿ. There is no pity counter in that formula because the game has none.
