This page is a planning aid for Trait Rerolls — not official drop rates from the developers.
Use the calculator above, then read the decision rules below. Free rerolls: codes. Priority who to trait: traits guide.
How to read the calculator
| Output | Meaning |
|---|---|
| Chance of ≥1 success | Odds you hit the target at least once in N independent rerolls |
| Expected rerolls | Average rolls until first success if each roll has chance p |
| ~50% / ~90% chance | Rough bank size if you want a coin-flip or high confidence |
Formula (independent rolls):
P(at least one) = 1 − (1 − p)^N
Presets are illustrative
Ultra-rare traits (often nicknamed Monarch-class) are much harder to hit than “good enough” traits. The presets below are example percents so you can plan a bank size:
- ~5% — solid / usable planning tier
- ~2% — strong niche
- ~0.5% — ultra chase
- ~0.1% — extreme chase
- Custom — enter a rate from your own tests
If the real pool differs, use custom %. Do not treat presets as official datamined rates.
Practical banking rules
- Main DPS first — only long-term units deserve chase banks.
- Stop at “good enough” early — clear content, then chase cosmetics/meta traits.
- Codes → bank → one unit — don’t split 200 RR across five epics.
- Before a banner you will main — hold RR if you know a new SS is coming this week.
- Expected value is not a guarantee — 1/p average still allows long dry streaks.
“How many RR should I have?”
There is no single number. Use the calculator:
| Goal | What to set |
|---|---|
| Just want a usable trait | Higher p preset, smaller N |
| Chasing a named ultra trait | Lowest p preset; look at 90% row — that’s the painful truth |
| Only 50–100 free code RR | Spend on main only; don’t open “Monarch or nothing” |
Also see farming sources on the traits page mindset: codes, challenges, events, battlepass — rates and caps change by patch.
Who to spend on (quick)
| Priority | Target |
|---|---|
| 1 | Best DPS you place every run (tier list) |
| 2 | Core support you always place |
| 3 | Secondary clear — only after 1 is fine |

FAQ
Are these official drop rates?
No. Official public tables are not mirrored here. Presets are for planning math only.
Why did I use 500 RR and still miss?
Variance. Even at 0.5% per roll, long dry streaks are normal. The 90% bank size exists for a reason.
Should I trade for rerolls?
Trading rules and risks: Trading guide. Prefer free codes and legitimate in-game sinks first. Never buy accounts or grey-market currency.
Does trading delete traits?
Community reports often say traded units can lose traits (and rules change). Confirm in-game / Wiki before you move a Monarch roll. Details on the trading page.
