Infinite Upgrades
by Z2SIX
Infinite Upgrades is a Forge and NeoForge mod where items gain levels through repeated attempts that can also fail, much like the upgrade loops of MMO games.
What it does
Players gather souls from defeated mobs with a Soul Cage and spend them on equipment at an Angel or Demon statue. Each attempt reports its success chance and soul cost before it runs. A success raises the item's level and its stats, while the next attempt becomes harder. A failure can destroy the item.
Two infusion paths shape growth: Angel Infusion gives balanced growth, while Demon Infusion favors min-max power. Actions shift a reputation between the two sides, and a reputation leaning toward Angel gives Angel attempts a small boost while penalizing Demon, with the reverse holding for Demon. Bonuses and penalties are configurable and clamped, and a hard level cap, 20 by default, limits progression.
The mod runs on Forge and NeoForge for 1.20.1 and 1.21.1, and the server and every player need it. Vanilla combat attributes such as attack damage, attack speed, armor, armor toughness and knockback resistance are supported out of the box. Modded attributes need to be added manually in the server config. Tools progress through a Block Speed bonus. The custom license means the code is not open source.

How it compares
Demon Slayer: Breath of Nichirin is a Forge, Fabric and NeoForge mod for 1.20.1 – 1.21.1 with the same client and server environment, but it is not open source and is under All rights reserved. Soul Cage is open source under the MIT License, covers Fabric and NeoForge for 1.20.1 – 1.21.1, and is server required with client optional, so players may skip it. Devon's Crucible - Soul Contracts is a Forge mod for 1.20.1 only.
