Arctics Undertale Souls
by ArcticHynez
Arctics Undertale Souls brings a Monster and Human soul system into Minecraft, with magic abilities and a choice of how to treat enemies.
What it does
The mod is built around the idea of a human and a monster who share a world, taken from the Undertale series. Players draw on a soul and use monster-style magic to move through the world, and enemies can be treated as foes or as friends.
A soul is chosen from seven traits: Determination, Bravery, Justice, Kindness, Patience, Integrity and Perseverance. Alongside them are Normal and Monster paths, and elemental spells for fire, water, ice, plant and lightning. Arctics Undertale Souls is client and server, so the server and every player need it. Builds cover 1.20.1 – 1.21.11 on Forge and NeoForge, and it is released under All rights reserved.

Use cases
Monster-themed playthroughs
Players who want to follow the monster side of the Undertale premise can choose the Monster path and use its magic across the world.
Peaceful or hostile encounters
Because each enemy can be treated as a foe or a friend, a single world can host both pacifist and combat-focused play.
Who it’s for: Players who enjoy the Undertale setting and want a magic-based soul system on Forge or NeoForge. Server owners who run the mod need to install it on the server and on every client.
