ABOUT THE DATAPACK

Adds a new boss into your world that you can summon after you defeat the wither.
In order to summon Null, you must create an alter (shown in the gallery) and then throw a nether star on top of it in the middle. Be careful though, this boss is dangerous and will destroy the environment, so fight him away from your precious structures.
For your endeavors, you may be rewarded handsomely.

Null has 3 Attacks:

  • Fireball, your standard fireball but stronger.
  • Lingering Potion, a potion filled with evil elixers thrown at you...
  • Clones, he summons false versions of himself to distact you!
  • (If Ascended) He may teleport to you periodically
  • (If Ascended) Can spawn multiple clones
  • (If Ascended) Can Fire many more fireballs at a time

REWARDS

He drops a new weapon, Null Blade, which is a voided netherite sword, but attacks faster, as well a a Nullite Pickaxe, a faster mining netherite pickaxe.
(If Ascended) Can drop a Nullified Core that has enhancements on it while in the offhand
(If Ascended) Can drop Stronger Version of the Null Blade and Pickaxe
