How to Get Corrupt Crown in Sailor Piece (2026)

If you’re in the late-game of Sailor Piece (Roblox), the Corrupt Crown is one of the rarest mythical materials you’ll need. This guide covers everything: how to obtain it, the real drop rate, fastest farming methods, and exactly how to use the Corrupt Crown for Corrupted Excalibur and Ascension 10.

How to Obtain Corrupt Crown in Sailor Piece

The Corrupt Crown drops exclusively from the Corrupted Knight boss on Boss Island. It is a mythical-tier item with an extremely low drop rate, so expect to run the boss many times.

Step-by-Step Guide:

1. Farm Dark Grails Collect Dark Grails by defeating high-level mobs in late-game areas (commonly dropped from corrupted or dark-themed enemies).
2. Teleport to Boss Island Head to the Boss Summoner NPC located on Boss Island.
3. Spawn the Corrupted Knight Pay the summoning cost:
   • 1× Dark Grail
   • 650,000 Money
   • 650 Gems
4. Defeat the Boss The Corrupted Knight spawns in the center of the arena with 750,000,000 HP. It hits hard, so prepare a strong damage build or bring a team.
5. Repeat Runs The Corrupt Crown has a very low drop chance. Keep spawning and defeating the boss until it drops.

Pro Tip: Use a private server to prevent other players from stealing your damage contribution and rewards.

What is the Drop Rate of Corrupt Crown in Sailor Piece?

The Corrupt Crown has one of the lowest drop rates among mythical materials:

• Drop Rate: Approximately 0.35% – 0.65% per kill (varies slightly by source and possible luck modifiers). Some reports list it around 0.59%.

Because of this low probability, most players need 100–300+ runs on average to get even one Corrupt Crown. Luck stats, runes, and high-damage contribution can slightly improve your effective odds.

Fastest Way to Farm Corrupt Crown in Sailor Piece

Here are proven tips to speed up your grind:

• Prioritize Damage Output — Rewards (including rare drops) scale with the percentage of damage you deal. Build for maximum DPS with the best late-game sword, fruit, and runes.
• Team Up Wisely — Group farming helps kill the boss faster, but focus on dealing high personal damage for better loot share.
• Use Private Servers — Avoid public servers where others can snipe kills or reduce your reward percentage.
• Optimize Currency & Resources — Pre-farm plenty of Money, Gems, and Dark Grails so you can chain summons without stopping.
• Luck & Drop Boosts — Equip any accessories, titles, or runes that increase rare drop rates or luck.
• Efficient Route — Combine Dark Grail farming with other late-game grinds to minimize downtime.

Many players report that running in a coordinated squad with strong damage dealers is currently the fastest method in 2026.
