Drop probability
Legendary summon odds
Estimate the chance of seeing at least one legendary skin in a chosen number of independent summons. Type the rate that matches your banner and bonuses. This does not model the 500-pull pity guarantee.
Chance of at least one success = 1 − (1 − chance per attempt) raised to the number of attempts.
The form uses an independent-roll model: the chance that at least one summon is legendary. It ignores the separate 500-summon pity counter. Enter 1 for the reported Regular or Specific rate, 2 for base Token Summons or for Regular with VIP or a Luck Potion, 3 for Token Summons with VIP, or 4 for Token Summons with a Luck Potion. Published tables list VIP and Luck Potion separately and do not show a combined rate. Unique Summons cannot drop legendaries, so leave that banner out of this form.
