Just Boss Swords

by JujuCorp

With Just Boss Swords, a player can take the power of a boss by holding its sword and use that boss's ability on right click.

What it does

The mod adds swords that borrow the powers of different bosses. Each sword starts at level 0 as a plain good sword, and its level rises by one after the player kills a Warden with it. Higher levels grant the boss ability, so the sword becomes more than a weapon over time.

At level 1 the sword gives permanent Resistance II and Strength effects while it is held. At level 2 a right click fires a sonic boom that deals 5 hearts of damage, bypassing armor, with a 1 minute 30 second cooldown. The server needs the mod to run these swords, while clients may leave it out.

Just Boss Swords is published for Fabric, Forge, NeoForge and Quilt, and a data pack build also exists. Files cover 1.21 – 26.3, with 1.3.1+mod for 26.3 as the latest file on every loader, released under All rights reserved and not open source.

Key features

  1. Boss power swords

    Each sword carries the ability of a boss, so a player can use different boss powers from one weapon.

  2. Level progression

    A sword starts at level 0 and gains a level for each Warden killed with it, up to level 2.

  3. Sonic boom ability

    At level 2 a right click releases a sonic boom that deals 5 hearts of damage and ignores armor.

  4. Cooldown on abilities

    The sonic boom has a 1 minute 30 second cooldown before it can be used again.
