Effects Rebalancer
by ImEden6
Effects Rebalancer lets a modpack author change the strength of Resistance, Regeneration and Absorption, the three potion effects it targets, through a configuration file.
What it does
Each targeted effect gets its own settings. Resistance uses adjustable damage reduction percentages per level, Regeneration sets how many health points are restored per tick, and Absorption controls how many extra hearts each level grants. Changes take effect without altering other status effects, so the rest of the vanilla behavior stays as it was.
The mod is a lightweight, configuration-driven addition that uses optimized Mixins to change vanilla behavior, which keeps its overhead low. Because it runs on client and server, the server and every player need it to keep effect values consistent. It is built for Fabric and has files for Minecraft 1.20.1 only, with the 1.0 release published on 2026-03-12.
The source code is public, and the project is released under the MIT License, so it is open source and can be read or reused under those terms. The mod has no required dependencies listed in the catalog, so Fabric is the only loader needed.
Key features
Resistance tuning
Damage reduction percentages can be set for each level of the Resistance effect.
Regeneration control
The exact number of health points restored per tick is set by the configuration for Regeneration.
Absorption scaling
The count of extra hearts granted per Absorption level can be changed to suit a pack's balance.
Configuration-driven design
Every value is read from a configuration file, so adjustments need no code changes or rebuilds.
Compatibility
Latest build for each game version and loader.
Only full game releases are shown. This mod publishes no snapshot builds.
Use cases
Who it’s for: Modpack authors and server owners who want to change how Resistance, Regeneration and Absorption behave, without editing vanilla game files or writing code.
How it compares
Potion Warning is client-side only, open source under the MIT License and published for 1.20.1, so it only changes what the player sees. Custom Blast Resistance is server-side only, open source under the CC0 1.0 Universal license and also for 1.20.1, so it runs without any client mod. Effects Rebalancer is client and server, so its balance changes need both sides to agree.
