Trait Reroll Analyzer

Calculate if chasing that Ruler trait is worth it or if you're about to burn 1200 gems for nothing. Real probabilities, real costs.

What this calculates:

  • Expected gem cost to get your target trait (average: ~800 gems for Mythic, 1200 if unlucky)
  • Probability per roll (Ruler = 0.83%, don't let anyone tell you it's "easy to get")
  • Pity system tracking (1200 rolls = guaranteed Mythic, but that's 1200 gems...)
  • ROI analysis (is 800 gems worth a 15% DPS increase? Depends on your unit)

My experience: Spent 43 rolls getting Ruler on Sun Jin Woo. Friend got it in 8 rolls. Another friend hit pity at roll 287. RNG is brutal. At least with this calculator you know what you're signing up for before you start.

Pro Tips for Trait Rerolling

💡

Prioritize Mythic Units

Ruler trait on Sung Jinwoo or Dragon Silver gives the best return on investment for end-game content.

⏰

Save Gems for Key Units

Don't reroll traits on low-tier units. Focus your gems on units you'll use in Infinite Mode and Raids.

🎯

Know When to Stop

If you get an Epic-tier recommended trait, it might be worth keeping instead of chasing Legendary traits.

📈

Consider Budget Options

Chakra and Enraged traits are excellent alternatives with much better drop rates than Ruler.
