About Just Boss Swords

From Modrinth

Just a mod that lets you borrow the powers of the different boss

Have you ever wanted to use the different boss powers? If so Just Boss Sword is there!

Cosmic Sword (Warden)

You get the cosmic sword by being the first to pick up the dragon egg, but in this state the sword is incomplete. To unleash his full potential, you will need souls...

By killing a warden or a player, you increase the level of the sword by one.

  • Lvl 0: Just a very good sword
  • Lvl 1: Give you permanently the resistance II and strenght I effects when you hold it in any of your hands
  • Lvl 2: When you right click, you do a sonic boom. It deals 5 hearts of damage no mather the armor and has a 1min30 cooldown.
