I watched the Corrupted Knight’s health bar melt with one last, sloppy crit and felt the sick thrill of being this close. You can taste the Corrupt Tyrant title and still lose nights to bad RNG. I’ll show you a straight path so you stop spinning your wheels and actually get the Saber Alter melee you want.
I’ve run these fights, tested drop rates, and wasted the same mistakes you probably have—so you don’t have to. You’ll get exact requirements, summoning steps, farming tricks, and how to pick up the F move with minimal pain. Read fast, act sooner, and keep a stack of Dark Grails ready.
How to Get Corrupted Excalibur in Sailor Piece
Observation: Players swarm every week around new melee drops because rarer weapons shift PvP and boss clears overnight.
Corrupted Excalibur is the Saber Alter-style sword that rewards patience and repetition. The pick-up logic is simple: earn the Corrupt Tyrant title, farm boss materials from the Corrupted Knight on Boss Island, then trade them at the Corrupted Knight NPC on the hand monument. The sword is not handed out — you buy it with specific drops.
- Corrupt Tyrant Title (1%)
- 25x Dark Grail (from any mob or mini boss)
- 15x Morgan Remnant (15%)
- 8x Alter Essence (5%)
- 3x Corruption Core (1.3%)
- 1x Corrupt Crown (0.5%)
If you’re new, don’t try to solo the highest difficulties right away. Level up, redeem Sailor Piece codes, and use Discord or YouTube guides to optimize your early clan, race, and trait choices. Corrupted Excalibur is a late-game tool: it will hit like a meteor, but you need the numbers behind it to land consistently.
How to Summon Corrupted Knight in Sailor Piece
Observation: Every boss in Boss Island uses the same summon UI, so once you learn one boss flow the rest are quick.
Only Boss Island hosts the Corrupted Knight. Walk to the Boss Spawner NPC, open the bosses list, and press spawn beside Corrupted Knight. Summoning costs scale with difficulty — bring Dark Grails, money, and gems.
| Difficulty Level | HP | Requirements |
|---|---|---|
| Normal | 750,000,000 | 1 Dark Grail 650,000 Money 650 Gems |
| Medium | 2,500,000,000 | 2 Dark Grail 800,000 Money 800 Gems |
| Hard | 6,000,000,000 | 3 Dark Grail 1,000,000 Money 1000 Gems |
| Extreme | 15,000,000,000 | 4 Dark Grail 1,500,000 Money 1,500 Gems |
How to Beat Corrupted Knight Quickly
Observation: Speed-running lower-HP bosses usually nets more materials per hour than slow-crawling higher difficulties.
Here’s the mental model I use: clear fast, repeat, upgrade. Equip luck titles and melee-boosting traits to nudge drop rates. Don’t chase the highest difficulty unless your TTK (time to kill) is comparable to Normal runs — small drop boosts rarely justify the time lost.
- Prefer lower-HP runs you can finish in seconds rather than long fights that increase drop chances by only a sliver.
- Use Sukuna V2’s F auto ability and stand on the finger beside the Corrupted Knight NPC to reduce knockback issues. Auto-F while perched and you’ll stay on the plate while dealing continuous damage.
- Rotate with friends or join active Discord communities to split spawns and speed up clear cadence. Many creators on YouTube post quick-loadout guides that shave minutes off your farming loop.
Should you farm Corrupted Knight on higher difficulty for better drops?
Short answer: not usually. The incremental drop boost doesn’t offset the longer fight times unless your clear speed stays competitive. Run Normal or Medium if you can clear in under a minute — you’ll get more attempts per hour and a steadier flow of cores and remnant drops.
Can you get the Corrupted Knight F move without the Alter clan?
No. To buy the F move from the mini Saber Alter NPC you must have the Corrupted Excalibur itself and be in the Alter clan. The vendor also requires 9x Corruption Core as part of the purchase.
Which materials are hardest to farm for Corrupted Excalibur?
The Corrupt Tyrant title is the stingiest drop and the main gating item. Corruption Core and Corrupt Crown are rare, but you’ll notice those drop more often as you stack runs. If you hate RNG, track runs with a spreadsheet or Discord bot so you stop wasting time on false randomness.
How to Get the Corrupted Excalibur F Move
Observation: Cosmetic and specialty moves usually live behind NPC vendors that require both the base weapon and clan alignment.
After you have the Corrupted Excalibur, find the mini Saber Alter NPC on Boss Island to purchase the F move. Requirements are straightforward:
- Corrupted Excalibur (base item)
- Alter clan membership
- 9x Corruption Core
Pro tip: don’t waste cores on higher-difficulty runs if you can’t clear them fast. Swap into a farming build (melee race/traits, haki, aura, runes) and hit the Corrupted Knight repeatedly. Use community tools — Roblox tags and popular Sailor Piece Discord servers — to time spawns with other players and reduce downtime.
Sailor Piece Corrupted Excalibur Moveset
Observation: Players choose weapons for two reasons — damage ceiling and practical usability; Corrupted Excalibur scores high on both, but it pushes you back a lot.
Corrupted Excalibur is a scorched comet of damage and a late-game weapon worth owning if your build supports melee stats. Its hits have heavy knockback, so group fights can be messy. Below is the tested moveset (melee build: races, traits, runes, haki, aura, and cosmetics equipped).
| Keybind | Description | Damage (max) |
|---|---|---|
| V | Emit an aura and perform a blade dance for AOE damage | 250 million |
| X | Slash the blade two times, then throw a forward beam | 90 million |
| Z | Throw a flashing beam in the direction of looking | 60 million |
| C | Charge a massive ray and throw it forward as an energy charge | 450 million |
| F | Deal constant damage, then throw a massive beam that deals even more damage | 1 billion |
The Corrupted Excalibur is a great finish for a melee roster if you can manage its knockbacks. Boss Island is a grindstone for your patience: tighten your loop, keep runs short, and trade smarter rather than harder.
Which setup will you try first: raw damage with heavy crit, or a lifesteal + sustain playstyle for long boss sessions?
