Anime Origins Reroll Calculator: Your Real Trait Odds
See your real chance of hitting any trait before you spend rerolls — including pity guarantees and both numbers whenever sites disagree.
Enter a target trait and reroll count
The interactive calculator turns your target trait, reroll count or confidence goal, and optional custom rate into a success probability, confidence table, pity bar, and cumulative odds curve.
Your reroll plan
Based on community-reported rates (checked 2026-08-15). Pick a trait, then choose how you want to plan.
Chance of hitting Immortal within 100 rerolls
Pity (community-reported) guarantees this trait by reroll 1300 — 1200 more from here.
Odds assume each reroll is an independent roll at the community-reported rate. Rates come from BloxInformer, Beebom and Pro Game Guides — not from the developers. See how we check sources.
Reading your result
Every reroll is an independent roll at your trait's rate, so your chance of at least one hit in N rerolls is 1 − (1 − rate)^N. When a pity count exists, the roll becomes guaranteed at that count — the curve flattens to 100% there. Sites sometimes publish different rates; in that case you get two curves so you can see both stories.
Worth knowing before you reroll
- • A unit stores two traits but only one is active — reroll the stored one you actually use.
- • The reroll station lives under the Areas menu; walk to the NPC to reroll.
- • Codes like AO hand out rerolls for free — claim them first.
Calculator FAQ
What are the odds of rolling the Immortal trait?
Community tables put Immortal at 0.1% per reroll, with a reported pity that guarantees it by 1,300 rerolls. Enter 1,300 in the calculator and it confirms the guarantee line.
How does trait pity work in Anime Origins?
If you keep rerolling without hitting a trait, the game reportedly guarantees it once you reach its pity count — for example Immortal at 1,300 and Overseer at 900 (community-reported numbers from BloxInformer).
Are these trait rates official?
No. The rates come from community tables (BloxInformer, Beebom, Pro Game Guides) checked 2026-08-15. Where two sites disagree, the calculator shows both curves instead of picking one.
How many rerolls should I save before rerolling?
Use the confidence table: about 7 rerolls gives you a 50% shot at a 10% trait, while a 95% chance needs roughly 29. For 0.1% traits like Immortal, plan around pity instead of luck.
