Thestrals
Very low chance chase target. Best overall, but expensive to force.
Pick your current race, set your remaining rerolls, choose a target tier, and get a practical keep-or-reroll decision before spending your attempts.
The calculator is conservative by design. It avoids wasting rerolls when your current race is already strong enough to progress.
Exact odds can change after updates, so use these as practical planning estimates rather than a guarantee.

Stellar Ambassador, Death Eater, Fiendish Demon, and Ice Crystal are practical keeps.
Keep only if it helps early survival or farming and rerolls are low.
Human is a baseline roll. Replace it before long routes or boss prep.
A good reroll plan has a stop point before you press the button.
Keep any useful A-tier or B-tier race. Reroll only Human or a race that blocks your current route.
Chase A tier or better, but stop on a race that fits your next goal.
You can chase Thestrals, but set an A-tier fallback before spending everything.
Chasing S tier is reasonable, but still stop if a strong A-tier race matches your build.
Use this quick reference when the calculator result needs context.

A-tier races are usually strong enough to farm, brew, and unlock more progress.
Know your keep targets before using the free rerolls from active codes.
A race that fits farming or survival can be better than a theoretical upgrade.
It compares your current race tier, remaining rerolls, and target tier to decide whether keeping or rerolling is the better practical choice.
Usually no if you have 15 or fewer rerolls. Keep useful A-tier races unless you have enough attempts to chase Thestrals.
Thestrals is treated as a very low-chance chase target. Even 25 rerolls can miss, so the safer rule is to stop on strong A-tier races when rerolls are limited.
