By taking part in Boss Rush mode, you can earn special rewards, including Rush Coins. To start this dungeon in Sailor Piece, though, a specific item is required.

Sailor Piece Boss Rush

Boss Rush is a new dungeon in Sailor Piece that features 15 waves in total. World bosses spawn every wave and are random each time.

The roster of bosses includes Ragna, Saber, Gojo, Sukuna, and more. Escanor is the Special Boss in Boss Rush mode. The higher the wave, and the greater the difficulty of the dungeon, the more HP each boss has.

How to Spawn Boss Rush

The only way to get the Boss Rush dungeon to spawn is by using a Rush Key.

How to Get Rush Keys

Rush Keys can be dropped by any NPC in the game, including mobs and bosses. Like with many other items in Sailor Piece, your best bet is to farm enemies of a higher level, as they have a higher chance of dropping rare items.

I recommend equipping luck-boosting items such as Runes and accessories. I’ve got a Luck Build guide to help you out if needs be.

Special Boss: Escanor

As mentioned, the Special Boss in Boss Rush is Escanor, and he has 3 potential drops upon defeat. One of these drops is the Escanor Sin of Pride Sword. To find out if it’s any good and if it’s worth the low drop rate, take a look at my Sailor Piece Sword Tier List.

• Escanor Sin of Pride (Sword)
  • 0.6% to 1.85% chance to drop
• The One (Title)
  • 0.85% to 1.75% chance to drop
  • Buff:
    • DMG increases by 65%
• Sun Armor
  • 0.5% to 1.5% chance to drop
  • Mythical rarity

    • E10
      • DMG increases by 95%
      • DEF increases by 125%
      • DMG Reduction increases by 30%

On Easy difficulty, Escanor has 90 million HP, and on Extreme difficulty, he has 36 billion HP.

Exclusive Titles

Unlocking milestones in Boss Rush rewards you with exclusive titles. Each difficulty level has a range of titles to collect, and they all require you to reach a certain spot on the leaderboards.

The most difficult one to get is most certainly Boss Rush Extreme #1, which is granted to players who reach first place on the Extreme difficulty Boss Rush leaderboards.
