This calculator is arithmetic on a table, not a live mixer. Enter quantities from your own Anime Defenders session. It will not click the shop.
Drop probability
Summon chance helper
Estimates the chance of at least one success over independent pulls. Type the percent shown on your banner. The default 1 is an example, not a published Secret rate, and this form does not model pity.
Chance of at least one success = 1 − (1 − chance per attempt) raised to the number of attempts.
Replace 1 with the banner chance you are actually rolling. Legendary pity at 50 pulls and Mythical pity at 400 pulls were reported for the standard banner in May 2024 guides; confirm the counter in the summon UI before you rely on it. This calculator ignores pity and rate-up.
Material planner
Trait Crystal gap
Subtracts the Trait Crystals you already hold from the crystals a planned number of rerolls would cost. Set crystals-per-reroll from the unit rarity. The default 4 matches the wiki cost for a Mythical, not every unit.
Required total = materials per upgrade × number of upgrades. Missing = max(required total − materials already owned, 0).
Community wiki costs: Rare 1, Epic 2, Legendary 3, Mythical 4, Secret 5. Exclusive and Ancient cells were blank in that table. Divine Trait Crystals are a separate item and are not included here.
