Wizard Alchemy Race Reroll Calculator
This Wizard Alchemy Race Reroll calculator computes your exact chance of rolling any race for a given number of Race Rerolls, using drop rates that sum to 100%.
Race Reroll Probability Formula
P(at least once) = 1 - (1 - p)n (p = race drop rate, n = rerolls)
Active codes 17kCCU, RELEASE and WIZARD grant 5 Race Rerolls each (15 total).

Rerolls needed for confidence
Each reroll is independent. Formula: P = 1 − (1 − p)n, where p is the race drop rate and n the number of rerolls. Drop rates are listed in the Races wiki.
When to use Race Rerolls
The calculator is useful because Wizard Alchemy races do not all behave like simple upgrades. Thestrals has the strongest current S-tier profile, but it only has a 1% roll chance. A 5% race such as Ice Crystal or Fiendish Demon is easier to chase, while a 10% race such as Death Eater can be a realistic early upgrade if you want attack power before spending more rerolls.
Current active codes provide 15 free Race Rerolls. Enter that number first, compare your target odds, then decide whether a rare race is worth chasing now or after more codes are released.

Wizard Alchemy reroll FAQ
What does at least once mean?
It means the chance that your target race appears one or more times across all rerolls. Duplicate rolls still count as misses after you already hit the target.
Why are low rates still risky?
Each reroll is independent. A 1% race stays rare even with many attempts, so the calculator helps set expectations before you spend your free code rewards.
Which race should I target?
Use the tier list for the build decision, then use this tool for the math. Damage races and movement races solve different farming problems.
