UNDERSTAND THE ODDS
A little probability. Less guesswork.
Use a probability you have verified yourself. This calculator does not know the game’s current rates or pity rules.
AT LEAST ONE SUCCESS
63.40%Illustration: 100 independent rolls at 1% per roll.
What this calculation assumes
Each roll has the same probability and is independent. The chance of one or more successes after n rolls is 1 − (1 − p)n. The target estimate is the smallest whole number of rolls that reaches your desired probability under those assumptions.
Pity, guarantees, changing rates and shared rarity pools can invalidate this model. A Supreme-category rate is not necessarily the rate of one named clan. A high cumulative probability is still not a guarantee, and the result is not a recommendation to buy rolls.
