  "textContent": "Saber Alter is a recently added melee weapon in the Roblox game Sailor Piece, and it sits comfortably among the most powerful specs available. Its moveset revolves around high burst damage and wide area-of-effect attacks, making it effective for both NPC farming and boss fights. Getting it, however, demands serious grinding — you need to repeatedly spawn and defeat a dedicated boss, collect six different material types, earn a rare title, and spend tens of thousands of gems.\n\n**Quick answer:** Spawn the Saber Alter Boss on Boss Island using 1 Dark Grail, 650,000 Money, and 650 Gems. Defeat her repeatedly until you collect the Corrupt Tyrant title (1% drop), 1 Corrupt Crown, 3 Corruption Cores, 8 Alter Essences, 15 Morgan Remnants, 25 Dark Grails, and 35,000 Gems. Then talk to the \"???\" NPC near the large stone hand rock on the right side of Boss Island to unlock the weapon.\n\nImage credit: __Roblox (via YouTube/@Default Dyver)__\n\n* * *\n\n### Spawning the Saber Alter Boss\n\nThe Saber Alter Boss does not appear on her own. You need to travel to Boss Island and spend resources each time you want to fight her. Every single spawn costs 1 Dark Grail, 650,000 Money, and 650 Gems. Because you will need to kill her dozens of times, stockpiling Dark Grails and currency before you start is strongly recommended.\n\nThe boss has close to 1 billion HP and uses flashy, hard-hitting abilities during the fight. Bringing a party makes each kill faster and splits the spawn cost burden if members take turns summoning. Expect to need well over 100 kills to collect every material, especially the Corrupt Tyrant title.\n\nTravel to Boss Island and summon the Saber Alter boss multiple times | Image credit: __Roblox (via YouTube/@Default Dyver)__\n\n* * *\n\n### Saber Alter Boss Drop Rates\n\nEvery defeat gives you a chance at one of six items. The most common drop is the Morgan Remnant, while the Corrupt Tyrant title is the rarest at just 1%. Plan your farming sessions accordingly — some players report needing around 145 kills before the title finally drops.\n\nItem| Drop Rate\n---|---\nMorgan Remnant| 52.50%\nAlter Essence| 19.31%\nAlter Armor (accessory)| 5.25%\nCorruption Core| 4.50%\nCorrupt Crown| 2.44%\nCorrupt Tyrant (title)| 1%\n\nYou will naturally accumulate plenty of Morgan Remnants and Alter Essences while chasing the rarer pieces. The Alter Armor accessory is a separate equippable item that provides significant stat bonuses, so hold onto it even though it is not required for the weapon unlock itself.\n\nImage credit: __Roblox (via YouTube/@Default Dyver)__\n\n* * *\n\n### Full Material Checklist for Saber Alter\n\nOnce you have every item below, head to the right-hand side of Boss Island and look for the large stone hand rock formation. A mysterious NPC marked with \"???\" stands there. Interact with the NPC to trade in your materials and unlock Saber Alter.\n\nRequirement| Quantity| How to Obtain\n---|---|---\nCorrupt Tyrant title| 1| Boss drop (1% chance)\nCorrupt Crown| 1| Boss drop (2.44% chance)\nCorruption Core| 3| Boss drop (4.50% chance)\nAlter Essence| 8| Boss drop (19.31% chance)\nMorgan Remnant| 15| Boss drop (52.50% chance)\nDark Grail| 25| Defeat any NPC or open chests\nGems| 35,000| General gameplay currency\n\n⚠️\n\nThe Corrupt Tyrant title also grants a permanent +75% Damage buff, so it is valuable beyond just being a crafting requirement.\n\n* * *\n\n### Farming Dark Grails Efficiently\n\nDark Grails drop from regular NPCs throughout Sailor Piece and can also appear in chests (secret, mythical, and legendary). You will need a large supply — 1 per boss spawn, 25 for the weapon unlock, and an additional 85 if you plan to unlock the F Move later. That adds up to well over 100 total.\n\nOne of the fastest farming methods uses the Quake Fruit at Shinjuku Island. Reset your stats and allocate everything into Power to maximize Quake ability damage. Position yourself at the center of the island where NPC groups continuously spawn on both sides. Use the C move to hit enemies on the left and right simultaneously, clearing waves quickly and maximizing your Dark Grail drop chances per minute.\n\nDark Grails drop from regular NPCs throughout Sailor Piece | Image credit: __Roblox (via YouTube/@Blox Fruits Guides)__\n\n* * *\n\n### Saber Alter Moveset — All Five Abilities\n\nSaber Alter is classified as a melee weapon and comes with five distinct abilities. The Z through V moves unlock immediately when you obtain the weapon; the F Move requires a separate unlock process described below.\n\nMove| Effect\n---|---\nZ Move| Launches airborne with temporary invincibility frames, then summons a ray dealing heavy AoE damage. Short cooldown (~4 seconds), highly spammable.\nX Move| Three consecutive slashes dealing heavy damage to enemies directly in front, finishing with a forward lunge.\nC Move| Rapid flurry of slashes dealing massive AoE damage in a frontal cone. Longer cooldown but enormous output.\nV Move| Cutscene attack where the user holds a stance, charges energy, and releases heavy burst damage to the target in front. Near-instant cooldown afterward.\nF Move| Cutscene where the user charges a ray of energy and releases it at the enemy's location after a brief delay, dealing massive AoE damage. Requires separate unlock.\n\nIn practice, the Z Move's low cooldown makes it ideal for sustained DPS, while the C and V Moves deliver the biggest single hits. Players testing the weapon have reported the C Move dealing around 1 billion damage and the F Move reaching upward of 3 billion at high stat levels, though exact numbers depend on your build and upgrades.\n\nSaber Alter is classified as a melee weapon and comes with five distinct abilities | Image credit: __Roblox (via YouTube/@Blox Fruits Guides)__\n\n* * *\n\n### Unlocking the F Move\n\nThe F Move is Saber Alter's ultimate ability and requires a separate set of materials plus a specific clan. After obtaining the base Saber Alter weapon, travel to Boss Island and find the second Saber Alter NPC on the left-hand side of the island, standing at the very edge.\n\nYou need all four of the following before the NPC will grant the F Move:\n\nRequirement| Details\n---|---\nAlter Clan| Legendary-rarity clan obtained through Clan Rerolls\nSaber Alter weapon| Must already be unlocked\nCorruption Core| 9 total (separate from the 3 used for the weapon)\nDark Grail| 85 total\n\nThe Corruption Cores are the main bottleneck here since they only drop at a 4.50% rate from the boss. Budget roughly 200 additional boss kills to collect 9 more cores, on top of the farming you already did for the base weapon.\n\nFind the second Saber Alter NPC on Boss Island to learn F Move | Image credit: __Roblox (via YouTube/@Blox Fruits Guides)__\n\n* * *\n\n### Getting the Alter Clan\n\nThe Alter Clan belongs to the Legendary rarity tier, so obtaining it through Clan Rerolls takes patience and luck. Keep using Clan Reroll items until you land on it — there is no targeted way to guarantee it drops on a specific roll.\n\nBeyond being a gate for the F Move, the Alter Clan provides strong passive buffs that synergize well with Saber Alter's burst-heavy playstyle.\n\nBuff| Value\n---|---\nDamage| +35%\nMax HP| +50%\nMelee Damage| +10%\nLuck| +12%\nAbility chain bonus| After using an ability, the next ability deals 1.5x damage\n\nThat ability chain bonus is particularly potent with Saber Alter since the weapon's cooldowns are short enough to keep the 1.5x multiplier active almost continuously.\n\nThe Alter Clan belongs to the Legendary rarity tier | Image credit: __Roblox (via YouTube/@noahhhhh)__\n\n* * *\n\n### How to Confirm You Unlocked Everything\n\nAfter interacting with the \"???\" NPC on Boss Island and meeting all material requirements, Saber Alter will appear in your weapon inventory as a melee-type weapon. Equip it and verify you can use the Z, X, C, and V moves. If you also completed the F Move unlock with the second NPC, the F ability will be available on the same weapon.\n\n🐛\n\nA visual bug may temporarily show your currency at zero after interacting with certain NPCs on Boss Island. Your money and gems are not actually lost — they reappear as soon as you defeat any NPC or boss. Do not panic or attempt refunds if this happens.\n\n* * *\n\nSaber Alter demands a significant time investment, but the payoff is one of the strongest melee specs in Sailor Piece. Between the weapon's five damaging abilities, the Corrupt Tyrant title's +75% Damage buff, and the Alter Clan's chain multiplier, a fully built Saber Alter setup can tear through bosses and NPC waves alike. Start stockpiling Dark Grails early, bring friends to Boss Island, and settle in for the grind.",
