Sailor Piece Reroll Priority — which reroll first?

The math behind spending your Rerolls in the right order. Covers budget thresholds, expected attempts by rarity, and the specific scenario where rerolling a good result is objectively wrong even if a better result exists.

TL;DR — the priority order

Trait Reroll — always first. Highest value per roll, highest drop rate for the reroll item itself.
Race Reroll — second. Biggest raw damage ceiling after trait.
Clan Reroll — third. Smaller stats but the signature passive carries significant build weight.
Aura Crate — whenever you get one, open it. No budget decision required.

Why trait first

Three reasons, in order of importance:

Highest value per slot. The top traits (Celestial, Secret Trait 3) hit +110–120% damage, +65–100% defense, and +25–30% cooldown reduction in a single slot. No clan or race in the game contributes that much total stat in one roll.
Highest drop rate for the reroll item. Trait Rerolls drop from most enemies in the game, including lower-level mobs. Clan and Race Rerolls skew toward bosses and higher-level tables.
Faster recovery from bad rolls. If your first 30 Trait Rerolls produce nothing Mythical, you're still at expected value and will likely accumulate another 30 during the next 1–2 hours of play. Clan or Race Rerolls take 2–3× longer to rebuild, so a bad streak costs more real time.

Expected attempts by rarity

Using community-consensus drop rates (real rates are not published — these are ballparks), here's what to budget before each reroll target for the three main reroll pools:

Any Epic or above: ~7 rolls expected, 23 for 95% confidence. Fast and reliable.
Any Legendary or above: ~23 rolls expected, 90 for 95%. Reasonable weekend target.
Any Mythical: ~100 expected, ~300 for 95%. Multi-day commitment.
Specific Mythical (e.g. Shadowborn specifically): ~500 expected, ~1,500 for 95%. Not recommended — reroll for "any Mythical" and take what lands.
Celestial (Secret-rarity trait): ~800 expected, ~2,400 for 95%. Reserved for min-max builds after everything else is dialed in.

Plug any of these into the Reroll Simulator to see the full probability curve, not just the single-number average. The mean is always higher than the median — about 30% of players will beat the mean count, 50% will beat the median, and 10% of unlucky runs will take 2×+ the mean. Plan for the median; stop before the 95% threshold if your stack is running dry.

When you should NOT reroll — the downgrade trap

This is the most common budget mistake. Suppose you have a Legendary clan and you're rerolling hoping for Monarch. The probability of each outcome on any single roll is:

Mythical (0 options for clans): 0% — not possible for clans in the current pool.
Any Legendary (Monarch or Voldigoat, 2 options): ~3.5%.
Monarch specifically: ~1.75%.
Epic-or-below: ~96.5%.

So every reroll attempt has a 96.5% chance of downgrading you. Unless you have a stack of 100+ Clan Rerolls and are willing to hold out until Monarch lands, rerolling is a losing expected-value move. The correct play is to keep the Legendary (even if it's Voldigoat rather than Monarch) and reroll a different slot instead.

The rule of thumb: before rerolling, look at your current roll's tier. If it's A-tier or above, rerolling is only correct when:

You have a specific target (not "anything better") AND
Your reroll stack covers the 75% confidence threshold for hitting that target AND
You can tolerate a temporary downgrade while the rerolls run.

Budgeting for a push

A realistic weekend reroll plan for a mid-game player (Level 800–1500):

Goal: any Mythical race.
Starting stack: 40 Race Rerolls accumulated from farming and codes.
Expected: 70% chance of hitting a Mythical within those 40 rolls.
Fallback: if you bust, you'll most likely have Legendary or Epic in the slot — a valid ceiling to continue with until the next reroll window.

Do NOT plan a push where burning the entire stack leaves you below your starting tier. If your current race is Oni (Mythical) and you're rerolling for Shadowborn specifically, 30 Race Rerolls isn't enough — the specific-entry math says you'd need ~500 for 63% confidence. Save the stack for a broader goal or wait until you have 5× more Rerolls than the mean.

Frequently Asked Questions

Which reroll should I spend first in Sailor Piece?

Trait first. Trait Rerolls drop at roughly 2–3× the rate of Clan or Race Rerolls, and a single Mythical trait (like Mythical Trait 2 at +85% defense / +65% damage / +15% CDR) contributes more raw stat value than any clan or race in the game. After trait, reroll race second for the raw damage ceiling, then clan third for the passive ability.

How many Rerolls do I need to hit a Mythical?

Expected attempts for "any Mythical" across any of the three systems sits at around 100. For 90% confidence, budget ~230 attempts. A specific Mythical (e.g. Mythical Trait 3 specifically, not any Mythical) roughly 5× those numbers since the Mythical drop splits evenly across the 5 Mythical variants in the pool.

Should I ever reroll away from a good clan / race / trait?

Only if the downgrade risk is acceptable. If you have a Legendary in the slot and you're rerolling for a specific Mythical, remember you'll see Common / Uncommon rolls far more often than a Mythical hit — so unless you're willing to accept going back to Common for the 1-in-100 chance at Mythical, keep the Legendary. The math is brutal: you have to survive many bad rolls before the target lands.

Are Trait Rerolls really that much more common?

Community consensus yes — Trait Rerolls drop from most enemies including lower-level mobs, while Clan and Race Rerolls are gated to mid-and-higher-level enemy tables and bosses. In a 1-hour grind session on a mid-level farm, expect 5–8 Trait Rerolls vs 1–3 Clan Rerolls and 1–2 Race Rerolls on average.
