Sailor Piece Power Remnant: How to Get and Use

How to Get and Use Power Remnant in Sailor Piece

The direct answer: Power Remnant is a drop-only crafting and rerolling item in Sailor Piece, obtained from boss and raid clears in the New World and Pirate King content tiers, and it is spent at the Blacksmith or Stat Reroll menu to reroll a single stat line on a weapon, accessory, or race slot. Most players should save it for weapons, because that is where the highest per-roll stat ceilings sit.

It is not purchasable from a shop vendor, and it does not drop from regular mob farming. That single fact shapes every decision below: you get Power Remnants at a slow, boss-gated rate, so wasting them on low-value gear is the most common mistake in the entire system.

What Power Remnant actually does

Power Remnant is a consumable that feeds the reroll function. It does not add a new stat slot and it does not upgrade a weapon’s tier — it swaps the current value of an existing stat for a new roll from that stat’s pool. In practice this means three things you need to know before you spend any:

• It works on one stat line per use. You pick the line; the game rerolls only that line. The other lines on the item are untouched.
• The new roll can be worse than the old one. There is no “keep or replace?” prompt in the base reroll flow, which is why the numbers on your current roll matter more than the item’s rarity.
• Rarity of the item raises the ceiling. A higher-rarity weapon rolls from a higher band on the same stat. A Power Remnant spent on common-tier gear is a Remnant thrown away, per the game’s own drop and stat documentation.

Power Remnant drop sources and rates

Rates below are the community-documented drop rates that have held steady across the recent content updates; treat them as bands rather than fixed numbers, since some bosses have a guaranteed-clear Remnant and others roll it from a percentage table. Rarity of the boss matters far more than how fast you can clear it.

Two practical reads from that table. First, an event boss with a generous table will out-earn a Pirate King raid per minute even though the raid has the better per-clear number — if the event is live, farm the event. Second, dungeon chests are the only source that stacks with something else you were already doing, so never skip a chest you walk past.

Step-by-step: using Power Remnant in the upgrade menu

The reroll flow is short, but the order of operations is where players lose Remnants. Follow it exactly.

1. Open your inventory and select the gear piece, not the Remnant. The reroll menu is entered from the item’s context menu, not from the consumable. Selecting the Remnant first is the single most common reason players think the item is “broken.”
2. Confirm the item is at your target rarity before spending anything. Reason: the rarity sets the stat roll ceiling. Rerolling mid-tier gear caps your best possible outcome below what the same Remnant would produce on endgame gear.
3. Tap the stat line you want to change. Only that line is affected. Reason: choosing the line first prevents the game from defaulting to the first slot, which is often a flat defensive stat you don’t want to touch.
4. Check the reroll cost shown in the confirmation box. Cost scales with item rarity and with how many times that specific line has already been rerolled. Reason: repeated rerolls on the same line get progressively more expensive, so chasing a perfect roll has diminishing returns.
5. Commit and read the new value before touching anything else. Record the old number if you’re chasing a threshold. Reason: without a keep/replace prompt, your only protection against a downgrade is knowing what you had.
6. Lock the item once you’re satisfied. Some gear can be locked to prevent accidental re-rolls or accidental selling. Reason: it costs nothing and prevents the worst possible outcome — losing a good roll to a mis-tap.

A concrete example

Say your sword has Melee Damage +18% on a 20% ceiling line, plus a flat +15 Defense you don’t care about. You have four Power Remnants. The correct play is zero rerolls on the Melee Damage line — 18% against a 20% cap has almost no room to improve and a real chance to drop to 8–12%. Spend all four on the Defense line instead, or bank them for a higher-rarity weapon where the Melee Damage ceiling is 30% or higher. Four Remnants into a near-capped line is four Remnants burned for a likely downgrade.

Which stat rolls are worth rerolling vs. keeping

Use the threshold table below as a keep/reroll decision rule. “Keep” means stop spending on that line and move your Remnants elsewhere.

Reroll priority by your situation

Your build and progression stage change the answer more than the raw numbers do. Match yourself to a row:

• Early game, low-level gear: don’t reroll at all. Bank every Remnant. The gear you’re wearing will be replaced, and Remnants carry forward while gear does not.
• Mid game, first endgame weapon: reroll only the primary damage line, and only until it clears the keep threshold. Stop there.
• Fruit-based build: reroll Devil Fruit Damage and Critical Chance; ignore melee lines entirely — half your Remnants would go to a stat you never use.
• Sword/melee build: melee damage first, attack speed second, crit third. Flat defense never.
• Full endgame, everything capped: rerolling is now cosmetic. Bank Remnants for the next content tier instead — new gear almost always raises the roll ceiling, which resets the whole calculation.

Durability and ownership realities

Three things wear out or bite you in this system. First, your Remnant supply — it is the scarce resource, not the gear, and it is gated behind group content you can’t infinitely spam. Second, reroll cost escalation: each successive roll on the same line costs more, so the fifth roll on one stat is dramatically worse value than the first roll on a different stat. Third, the ceiling reset: raising an item’s rarity, or moving to next-tier gear, invalidates your previous rolls’ relative value, which is why hoarding a small buffer of Remnants is almost always correct. The common mistake is spending down to zero on a piece you’re about to replace.

Frequently Asked Questions

Can you buy Power Remnant with in-game currency?

No. Power Remnant is drop-only, so the only way to build a supply is clearing the boss, raid, and dungeon content listed above. Because there is no vendor, the market price people quote for it reflects trading demand rather than a fixed shop rate, and it moves with each update.

Does Power Remnant reroll the whole item or just one stat?

Just one stat line, and only the line you select. The rest of the item’s rolls are preserved. This is why it is safe to reroll a bad defensive line on an otherwise good weapon without risking the stats you already like.

Is it worth rerolling a stat that’s already near its maximum?

Almost never. If your roll is within a few points of the ceiling, the realistic outcomes are a small gain or a large loss, and there is no keep-or-replace prompt. Spend that Remnant on a different line or bank it for higher-rarity gear with a taller ceiling.

What is the fastest way to farm Power Remnants?

During a live event window, event bosses — they combine the highest per-minute rate with short clear times. Outside events, a full Pirate King raid gives the best per-clear yield, while solo New World world bosses are the better option if you can’t assemble a group.

Should I reroll my race slot or my weapon first?

Weapon first, every time, unless your race roll is unusually far below its band. Weapons carry the largest stat ceiling and the largest share of your total damage, so the same Remnant buys more on a weapon than anywhere else.

Do Power Remnants carry over between updates?

Yes — they sit in your inventory as a consumable, so they persist across content updates. That is the main argument for banking them: a new tier of gear usually raises the roll ceilings, which makes the same Remnant worth more after the update than before it.
