Take Back the Night

Fabric version requires Fabric API and 0.15.11 or newer

NeoForge 1.21.1 version requires 21.1.215 or newer

This mod adds a Herobrine boss that is very inspired by the Mutant from Fargo's Souls

If you don't know, the Mutant is a modded Terraria boss that uses the attacks of all vanilla bosses. 

I wanted to do something similar so I made this mod.

Summoning

-To summon ya boi, its straight forward. Just build your stereotypical Herobrine altar.

-It accepts netherrack for the top, any torch for the side, any beacon block for the base.

Attacks

-Teleports in front of you and claps his hand, creating a sonic boom similarly to the warden.

-When below 25% health, this attack is replaced by a forward flip, followed by a shockwave.

-Teleports on top of you and starts charging up a creeper explosion.

-When below 25% health, this attack is replaced by a sweeping guardian beam.

-Flies upwards and summons a larger ghast fireball, then throws it to you.

-When below 50% health, the fireball is replaced by 3 slow-moving dragon fireballs.

-Stomps the floor and creates a circle of evoker fangs.

-When below 50% health, this attack is replaced by an aerial teleport followed by a barrage of harming potions.

-Levitates upward and summons a swarm of non-homing shulker bullets that are then launched to the target.

-When below 50% health, this attack is replaced by a storm of wither skulls.

-When below 50% health, Herobrine gains a new attack. He will jump back, then perform 3 back-to-back riptide dashes. Getting hit by this attack strikes you with lightning.

Killing Herobrine gives you the "Take Back the Night" advancement and 650 xp on first kill (500 on any other kill).

Also, it is worth noting that only 1 Herobrine can be summoned at a time.
