This datapack supports minecraft versions from 1.16 to 1.20.
To summon Herobrine Boss, you need to create a shrine like this. You will need 5 gold blocks, 4 netherite blocks, 4 redstone torches, 1 netherrack, 1 flint & steel, 1 nether star.
Put netherrack on the top of shrine.
Throw a nether star inside the fire and get away from that area quickly before Herobrine spawns with a harmful tornado.
During fight, Herobrine will summon its minions randomly. So beware. Vexes are destructive so be sure to kill them upon spawn.
Herobrine Boss drops lots of valueable items upon its death. Adding to valueables, it drops its skull which contains superpowers of Herobrine.
Herobrine Boss Skull gives you slow falling effect, 50% extra speed, and you become immune to knockback damage completely, adding a soul fire trail whenever you are on the ground, and magic enchant fly(check description).

Adds Herobrine Boss Fight to Survival Minecraft. Only for really skilled players.
