Ultimate Mine Piece

Ultimate Mine Piece is an addon for Orca-san's Mine Piece that expands the mod with new Haki systems, advanced combat mechanics, Devil Fruit abilities, NPC improvements, progression systems, and additional content inspired by the One Piece manga and anime.

Haki Systems

Conqueror's Haki — Clash System

Powerful warriors with Conqueror's Haki (Sovereign Haki Level 4+) can trigger cinematic Haki clashes when fighting other powerful opponents.

Clash Requirements

• Both entities must be actively fighting.

• Maximum clash range is 100 blocks and can be configured.

• Both fighters require Sovereign Haki Level 4+.

• Each entity has a 30-second cooldown between clashes.

Clash Outcomes

Both fighters have Conqueror's Haki:

• Triggers an epic head-on Haki clash.

• The fighter with the higher Haki level wins.

• The winner receives Damage, Resistance, and Speed buffs.

• The loser receives Weakness, Slowness, and Confusion.

Only one fighter has Conqueror's Haki:

The result depends on the difference in strength:
