If you want to push your build in Sailor Piece, stat rerolling is one of the most important systems to understand. The sailor piece z stat chance is extremely low, but the payoff is huge if you land a Z tier on the right stat. This guide breaks down how stat rerolling works, what the known tier chances look like, how much gems you may need, and the best way to approach rerolling without wasting resources.
What is stat reroll in Sailor Piece?
Stat reroll lets you spend gems to change the tier of your character stats. Each stat has tiers from F up to Z, and higher tiers give stronger bonuses.
You can reroll:
- One stat at a time
- All stats together
- Selected stats through auto roll
You can use stat reroll at the stat roll NPC on Sailor Island. There is also a stat roll NPC in the Second Sea on World Island.
Reroll cost at a glance
| Reroll type | Cost |
|---|---|
| One stat | 1,000 gems |
| All stats together | 500 gems each? |
| Auto roll selected stats | Scales with the number of selected stats |
Note: In practice, rerolling multiple selected stats costs more because each stat is charged separately. For example, rolling three selected stats can cost about 3x the normal single-stat price.
Sailor Piece stat tiers and boosts
The exact bonus depends on the stat. Damage and defense are the clearest documented examples.
| Tier | Damage | Defense |
|---|---|---|
| F | +5% | +5% |
| E | +7% | +7% |
| D | +10% | +10% |
| C | +12% | +12% |
| B | +15% | +15% |
| A | +17% | +17% |
| S | +20% | +20% |
| SS | +25% | +25% |
| SSS | +30% | +30% |
| Z | +37% | +40% |
Even though some stat bonuses look small at first, they add up fast, especially on high-value stats like damage, crit chance, and crit damage.
Sailor Piece Z stat chance
The Z stat chance is extremely rare. Public info from the in-game community sources points to a chance of about 0.0125%, which is roughly 1 in 8,000 rolls.
That means:
- You may get lucky early
- You may also spend millions of gems without seeing a Z tier
- There is no guaranteed Z pity
Z stat chance and expected gem costs
| Result | Approximate chance | Rough expectation |
|---|---|---|
| SSS | 0.05% | About 1 in 2,000 by raw chance, but pity helps |
| Z | 0.0125% | About 1 in 8,000 |
| Z with bad luck | — | 5M to 12M+ gems possible |
From player experience shared in the source material, a single Z stat can cost anywhere from 2 million to 12 million+ gems, depending on luck.
Is there pity for Z stats?
No. The available information indicates that Z stats do not have a pity system.
However, there is pity for lower high-tier results:
| Tier | Pity |
|---|---|
| SS | 200 rolls |
| SSS | 500 rolls |
This is why many players aim to secure a Z stat first, then clean up the rest of their build afterward.
Best stats to chase with Z tier
Not every stat is equally valuable for every build, but some are especially strong at Z.
High-priority Z stat targets
| Stat | Why it matters |
|---|---|
| Damage | Strong overall boost to combat output |
| Critical chance | Hard to max and very valuable |
| Critical damage | Massive scaling for crit-focused builds |
| Cooldown reduction | Helps keep skills active more often |
Lower-priority Z stat targets
| Stat | Why it may be less urgent |
|---|---|
| Defense | Useful, but often less important than damage for faster progression |
| Damage reduction | Can be strong for survivability, but build-dependent |
If you are deciding where to spend your gems first, most players will get more value from Z on damage, crit chance, crit damage, or cooldown reduction than from defensive stats.
How many gems should you save before rerolling?
A safe recommendation is to save at least 10 million gems before seriously chasing Z stats.
That does not mean you must spend that much every time, but it gives you enough room to:
- Keep rerolling through bad luck
- Still have gems left for SSS pity
- Avoid getting stuck with nothing meaningful
Gem-saving plan
| Gem total | What to do |
|---|---|
| Under 500,000 | Save for later |
| 500,000+ | Consider finishing with SSS if needed |
| 5M+ | Realistic Z stat chase begins |
| 10M+ | Best comfort zone for Z hunting |
Best reroll strategy for Z stats
If your stats are mostly low or mediocre, the best approach is often to reroll all stats together until you get at least one Z.
Why this works:
- You are rolling more stats per attempt
- You increase your chances of landing a Z somewhere
- You can fix the rest later with smaller gem spending
Recommended reroll order
- Start with all-stat rerolls if you have enough gems.
- Stop when you land a Z on a stat you like.
- Use remaining gems to chase SSS on other stats.
- Avoid auto rolling too many selected stats unless necessary.
Why not auto roll too many stats?
Because it becomes expensive fast. Since each selected stat is charged separately, rolling several at once can drain gems much faster than expected.
Example build priority for rerolls
Here is a simple practical priority list.
| Priority | Stat type |
|---|---|
| 1 | Damage |
| 2 | Critical chance |
| 3 | Critical damage |
| 4 | Cooldown reduction |
| 5 | Defense / damage reduction |
If your build is focused on bossing or burst damage, crit-based stats become even more important.
How strong is Z critical damage?
Community testing suggests that Z on critical damage can be especially impactful. One player example showed a critical damage build with very high crit damage scaling, and the extra multiplier made a noticeable difference in damage output.
That is why many players consider crit-related Z stats among the best rolls in the game.
Where to get gems for stat rerolls
The sources mentioned most often by players are:
- Chests
- Bosses
If you are saving for Z rerolls, focus on consistent gem farming before spending. Stat reroll is a long-term system, not something you want to gamble on with a low gem balance.
Practical reroll tips
- Don’t spend all your gems on selected auto roll unless you really need to
- Prioritize stats that fit your build
- Keep enough gems for SSS pity
- Remember that Z has no pity, so luck matters a lot
- Check the in-game NPC and stat screen after updates in case costs or rates change
Quick summary
| Topic | Takeaway |
|---|---|
| Z stat chance | About 0.0125% or 1 in 8,000 |
| Z pity | None |
| SSS pity | 500 rolls |
| Best gem target | 10 million+ |
| Best Z stats | Damage, crit chance, crit damage, cooldown reduction |
The short version: Z stats are very rare, expensive, and powerful. If you want the best results, save a large gem bank, reroll smartly, and focus on the stats that matter most for your build.
