The Corrupt Crown is one of the rarest and most valuable materials in Sailor Piece.

If you are in the late game, you will definitely need it for Ascension 10 and unlocking powerful gear like the Corrupted Excalibur.

However, getting this item is not easy. With an extremely low drop rate, farming Corrupt Crown requires patience, strategy, and efficient gameplay.

What is Corrupt Crown in Sailor Piece?

Corrupt Crown is a Mythical rarity material used for high-level progression.

Why it is important:

  • Required for Ascension 10
  • Needed to unlock Corrupted Excalibur
  • One of the rarest drops in the game

If you are aiming for endgame builds, this item is essential.

How to Get Corrupt Crown in Sailor Piece

To obtain the Corrupt Crown, you must defeat a specific boss.

Step 1: Farm Dark Grail

Before you can fight the boss, you need Dark Grail.

  • Dropped from high-level mobs
  • Required to spawn the boss
  • Farm multiple before heading to Boss Island

Step 2: Go to Boss Island

  • Use the portal to teleport
  • Head to the Boss Summoner NPC

This NPC is used to spawn special bosses.

Step 3: Spawn Corrupted Knight Boss

To summon the boss, you need:

  • 1x Dark Grail
  • 650,000 Money
  • 650 Gems

Once you meet the requirements, spawn the boss in the arena.

Step 4: Defeat Corrupted Knight

Here are the boss details:

  • Boss Name: Corrupted Knight
  • HP: ~750 Million
  • Drop Rate: ~0.59% (very low)

This is where the real grind begins.

Step 5: Repeat the Process

Since the drop rate is extremely low:

  • Farm Dark Grails
  • Spawn boss repeatedly

You may need several runs before getting even one Corrupt Crown.

  • Clans
  • Traits

Even small boosts help over multiple runs.

Prepare Multiple Summons

Do not farm one boss at a time.

  • Gather multiple Dark Grails
