NETHER MOBS+ Data Pack!

Adds 4 new mobs, 1 new boss, 10 new items including a weapon, a buildable nether core (nether beacon), and more.

The wraith is a cool mob with 2 attack modes. Credit to nBow for the model.
These are items that are added with this data pack. Some of them are drops, and some are craftable. Check out video for full details.
The Nether gun has 3 modes: Explode, normal shot, lava shot.
It's a laser shark. Spawns in lava lakes or can be fished with netherite fishing rod.
The nether's beacon equivalent (If Mojang doesn't add one after I make this) is the nether core, which gives chosen effects to players within 64 blocks.
