Frequently Asked Questions
What are the real Mythic race odds?
The Mythic race sits at roughly 0.15% per roll (creator-verified). The planner applies the exact formula 1 − (1 − 0.0015)^n, so 100 race rerolls give about a 13.98% chance of at least one Mythic.
Do Trait rerolls use the same odds?
Trait rarity odds are not yet published. The planner tracks your Trait Reroll count for bulk-rolling strategy, but does not show a fixed percentage — stack code grants (FruitBasket, NewYouNewCrew) and confirm traits in-game.
Where do rerolls come from?
Codes. HappySunday grants 20 Race Rerolls; FruitBasket and NewYouNewCrew grant Trait Rerolls. Save several drops and roll in bulk rather than one at a time.
