Quick answer: Shadow Monarch is the strongest sword in Sailor Piece right now, and Anos, Gilgamesh, Strongest in History, and Strongest of Today are the top melee specs. If you're a newer player, Ichigo is the most accessible S Tier sword, and Qin Shi is the cheapest worthwhile melee spec to grind toward.

Sailor Piece splits its weapon system into two distinct categories — swords and melee specs (orbs) — and picking the wrong one in either slot can stall your progression hard. Swords carry visible rarity tiers from Rare up to Mythical, while melee specs are unlocked by trading cash, gems, and crafting materials to Trainer NPCs scattered across the map. Both weapon types matter for farming, boss fights, and PvP, and both scale differently with upgrades. The rankings below reflect the current King & Monarch update and will shift whenever balance patches land.

Sailor Piece Sword Tier List
All ten swords are ranked below. Rarity alone doesn't determine a sword's placement — upgrade scaling and ability damage carry just as much weight.
| Tier | Sword | Rarity | Key Strengths / Weaknesses |
|---|---|---|---|
| S | Shadow Monarch | Mythical | Highest raw ability damage in the game; massive critical-hit potential melts bosses and dominates PvP |
| S | Shadow | Mythical | Best sword for high-level farming; exceptional endgame damage once fully upgraded |
| S | Ichigo | Mythical | Most accessible Mythical (obtainable via 500 Boss Tickets or crafting); reliable across all content |
| A | Rimuru | Mythical | Scales extremely well with upgrades; massive late-game damage but requires heavy investment |
| A | Ragna | Mythical | Consistent DPS with excellent burst against bosses; good bridge weapon toward S Tier |
| B | Aizen | Mythical | Strong against bosses but locked into Aizen-specific builds; limited versatility |
| B | Jinwoo | Mythical | Solid burst damage for mid-game; outclassed by stronger Mythicals in endgame |
| B | Saber | Legendary | Easy to get (65 Boss Tickets or 2% Saber boss drop); falls off significantly late |
| C | Dark Blade | Epic | Cheap at 250K cash + 150 Gems; poor scaling makes it obsolete by mid-game |
| C | Katana | Rare | Starter weapon for 2,500 cash; lowest damage output of any sword — replace immediately |
How to Get the Best Swords
Shadow Monarch sits at the very top but demands the steepest entry cost. You need the "King of Shadows" title, the Jinwoo sword already in your inventory, 10 Monarch Cores, 5 Monarch Essences, 2 Kamish Daggers, and 1 Shadow Crystal. That means you'll likely pass through Jinwoo on your way up, which itself costs 2.5 million cash, 7,500 Gems, and several crafting drops.
Shadow is slightly more straightforward — speak to the Shadow Trainer on Dungeon Island with 10 million cash, 15,000 Gems, 8 Void Seeds, 1 Atomic Core, 4 Shadow Essences, and 20 Umbral Capsules. No title requirement, but the material grind is real.
Ichigo offers two paths. You can exchange 500 Boss Tickets at the Boss Exchange, or talk to Ichigo at Hueco Mundo with 5 million cash, 8,500 Gems, 4 Spiritual Cores, 2 Soul Flames, and 8 Soul Fragments. The Boss Ticket route makes Ichigo the easiest Mythical to reach for players who farm bosses consistently.

Sailor Piece Melee Spec (Orb) Tier List
Melee specs work differently from swords. They're unlocked through Trainer NPCs by exchanging coins, gems, specific items, and sometimes titles or clan membership. Every player starts with Combat, the default spec, which should be replaced as quickly as possible.
| Tier | Melee Spec | Key Strengths / Weaknesses |
|---|---|---|
| S | Anos | Extremely heavy ability damage; excellent late-game scaling; strong in farming and boss fights. Requires "Demon King" title + Voldigoat Clan |
| S | Gilgamesh | Consistent DPS; very effective against groups; reliable late-game pick. Requires "Golden King" title + 25M cash + 22,500 Gems |
| S | Strongest in History | Exceptional burst damage; dominates high-level bosses. Requires "Disgraced One" title + consuming 20 Awakened Cursed Fingers |
| S | Strongest of Today | Great scaling with ability upgrades; strong combat utility and survivability. Requires "Strongest Sorcerer" title + consuming 6 Six Eyes |
| A | Conqueror Haki | Best melee spec for mob farming and wave clearing thanks to AoE + crowd control |
| A | Madoka | Reliable all-rounder; scales well into endgame; consistent in PvP and boss encounters |
| B | Sukuna | High DPS with strong AoE and damage-over-time; great against grouped enemies but requires heavy grinding |
| B | Qin Shi | Strong mid-game spec for sustained fights; cheap to obtain (250 Boss Tickets or 500K cash + 2,500 Gems); relies on summons |
| B | Alucard | Exceptional regeneration and ranged zoning; one of the hardest specs to unlock (needs Vampire Race + "Vampire King" title) |
| C | Gojo | Niche PvP value from mobility; low overall DPS; heavy investment needed |
| C | Yuji | Decent AoE on paper but lacks synergy with most builds |
| C | Combat | Default starter spec; very low damage scaling; becomes a liability past early progression |

Best Melee Spec for Farming vs. Bosses vs. PvP
If your priority is clearing waves of mobs quickly, Conqueror Haki is arguably the single best melee spec in the game for that job. Its AoE and crowd control let you pull large groups and wipe them efficiently, which makes it ideal for grinding experience and item drops even though it sits in A Tier overall.
For boss fights, the four S Tier specs all perform well, but Strongest in History stands out with its burst damage against high-level bosses. Anos is the most well-rounded of the four, excelling in both farming and boss encounters without a clear weakness.
PvP is where tier placement gets a little murkier. Madoka performs consistently in player-versus-player combat despite being A Tier, and Gojo has niche mobility advantages that can catch opponents off guard — though its low DPS makes it hard to recommend as a main spec.

Progression Path for New Players
You start with Combat (melee) and Katana (sword). Both should be replaced as soon as you can afford upgrades. The cheapest meaningful sword upgrade is Dark Blade at 250,000 cash and 150 Gems from the Dark Blade Seller on Snow Island. It won't carry you past mid-game, but it's a clear step up from Katana.
For melee, Qin Shi is the best early investment. You can get it for 250 Boss Tickets through the Boss Exchange or by trading 500,000 cash, 2,500 Gems, 3 Imperial Seals, and 7 Jade Tablets. It's versatile enough for mid-game progression and gives you time to farm toward an S Tier spec.
On the sword side, work toward Ichigo as your first Mythical. The 500 Boss Ticket path is straightforward if you're farming bosses regularly, and Ichigo remains useful all the way through endgame content. From there, you can decide whether to chase Shadow Monarch for raw power or Shadow for farming efficiency.

Where the Rankings Disagree
One notable point of disagreement across the community involves Rimuru. Some players rank it alongside Shadow Monarch and Shadow at the very top of the sword tier list due to its high DPS, large AoE, and crowd control. Others place it a step below because of its steep acquisition cost (30 million cash, 20,000 Gems, the Demon Lord title, and multiple rare materials) relative to its performance gap over cheaper A Tier options like Ragna. The consensus leans toward Rimuru being excellent but not quite on the same level as Shadow Monarch's raw ability damage.
Aizen is another sword that shifts depending on who you ask. It performs well against bosses and has strong raw damage, but its effectiveness drops sharply outside of Aizen-focused builds. Players who build specifically around it may find it competitive with A Tier swords, while generalists will feel its limitations.
Complementing Your Weapons with Race and Trait
Your weapon choice doesn't exist in a vacuum. The Slime race grants a +17% Sword Damage Multiplier alongside +65% Damage and +70% Maximum HP, making it the best race for sword-focused builds. If you're leaning into melee specs instead, Servant offers a +17% Melee Damage Multiplier with similarly strong defensive stats. Kitsune is the go-to for grinding thanks to its +25% Luck Multiplier.
For traits, Celestial is the strongest overall pick with 2.20x Damage, 1.65x Defense, and 30% Cooldown Reduction. Pairing Celestial with Slime or Servant gives you the highest possible damage multipliers for your weapon type.

Sailor Piece's weapon meta will continue to evolve as new swords, melee specs, and balance changes arrive. For now, investing in Shadow Monarch or any of the four S Tier melee specs will carry you through every piece of content the King & Monarch update has to offer. If you're still early in your progression, prioritize Ichigo and Qin Shi — they're the most efficient stepping stones toward the endgame builds that actually matter.
