Double Trait Warning
Double traits (e.g., "Double Duelist") exist but are extremely rare. The probability is roughly p² (probability squared), making it nearly impossible to target. Don't plan builds around getting double traits.
❓ How to Use the Trait Reroll Simulator
- Select Target Trait: Choose the specific trait you are aiming for (e.g., Mythic - Sniper) from the dropdown menu.
- Check Probabilities: The tool loads canonical Trello-listed probabilities, or you can enter a custom chance if testing hypothetical scenarios.
- Review Results: The calculator displays the expected number of Reroll Tickets or Gems needed to hit your target.
- Understand Pity: Pity values are displayed only as legacy review-needed references until independently confirmed.
Formula & Pity System
This calculator uses the Geometric Distribution for traits with canonical probabilities:
- Expected Value (E): E = 1/p, where p is the probability
- Percentile (k attempts for X% chance): k = ⌈log(1-X) / log(1-p)⌉
- Pity System: Astral 277 and Fortunate 125 are legacy_needs_review references, not confirmed caps.
Assumptions: Each reroll is independent and Trello-listed probabilities are current as of the canonical dataset verification date.
