Monte Carlo

How many Chrono Crystals a banner really takes: a configurable step loop, pity awarded after the full 10-pull.

Parameters

Target copies

Trials

Pity a guaranteed copy after N pulls

Pulls until pity multiple of 10

On a natural pull

Pity system lifetime

Steps 10 cards per step

Number of steps

Return to step after the last
