Anime Origins Summon & Reroll Planner

Plan summons or trait rerolls with the rate and cost shown in your current game panel. No Anime Origins rate, cost, or pity threshold is assumed.

Enter current panel values, then compare the outcomes

Summon mode requires your current chance and roll or budget values, then returns independent-roll odds, expected, median, and target rolls, cost, plus a separate user-entered hard-pity cap.

Trait mode accepts the current per-reroll chance, rolls or budget, optional cost, and user-entered pity, then shows probability and planning outputs with assumptions. Both modes use numerically stable probability math and never assume a fixed Anime Origins preset.
