What Luck means here
We multiply your assumed per-roll chance by the number you enter. That is a scenario, not Mine a Planet's confirmed formula.
What it never promises
Random outcomes can take longer than the average. This model does not include pity, guarantees, time estimates, or hidden game rules.
