Harrowing Hells

by TheExiIedFeIIow

Harrowing Hells adds Cinderscourge, a summonable boss mob with a varied set of attacks, to Minecraft Java Edition 1.21.1 and the 1.20 – 1.21.1 range.

What it does

Cinderscourge is a boss entity that can be summoned in survival. Its attacks include leaps that land with a shockwave, a ring of meteors that orbit it, red projectiles that trail through the air and burst into smaller projectiles, and melee strikes that set targets on fire. When it loses sight of its target, it slowly regenerates health.

The boss is designed around melee combat, so players should bring a sword, axe, shield or bow. Fire resistance and speed potions are recommended before a fight, and the author suggests a stack of food with golden carrots or golden apples, plus a few ender pearls for escape. Netherite gear is noted as helpful. Boss fights can also be started through an admin command for testing.

It is required on the server and optional for players. It is released under the MIT License and is not open source. Files are published for Fabric, Forge, NeoForge and Quilt, and as a data pack, for 1.20, 1.20.1, 1.21 and 1.21.1, with 1.1.4 for 1.21.1 as the latest build. Boss Checklist & Field Guide - Harrowing Hells Compatibility requires it, and Boss Warps is an optional companion.

Key features

  1. Summonable boss

    Cinderscourge can be called in survival and fought in mob battles against other mobs.

  2. Attack patterns

    Leaps with shockwaves, orbiting meteors, and projectiles that split into smaller ones give each phase a distinct threat.

  3. Regeneration and ignition

    The boss heals when it has not seen its target for a few seconds, and its melee hits set opponents on fire.

  4. Fire resistance

    The mod includes fire resistance for players, which matters given the ignition attacks in the fight.
