In-Effect!
by BoTryken
In-Effect! lets server owners and modpack builders grant vanilla and modded status effects permanently, with the list and durations set in a config file.
What it does
Permanent effects can be assigned to players through a config file, so an effect such as Speed III stays active without being reapplied. The effect list lives in effect-common.toml inside the config folder, where a new effect is added by writing its entry, and changes are read back in real time, so edits take hold without restarting the game. Vanilla effects and effects from other mods can both be listed.
Effects granted this way resist the usual ways players clear them: drinking milk does not remove them, and they persist through death. The mod targets modpacks and servers that want a fixed set of effects for every player. Both sides need the mod, since the environment is client and server. In-Effect! is published for Forge and NeoForge, with files for 1.20.1 and 1.21.1, and it is not open source, being released under All rights reserved.
Key features
Permanent status effects
Vanilla and modded status effects can be set to last indefinitely, so players keep them without renewing.
Editable effect list
Effects are added or changed in effect-common.toml, and the new entries apply in real time without a restart.
Effect icons
Each active effect can show its icon on the player's screen, so the active effects are visible at a glance.
Toast and transparency options
Toast notifications can be turned on or off in the screen corner, and particles can be made partly transparent.
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 creators and server owners who want permanent effects on a fixed list, and who can edit a TOML config file to change it.
How it compares
Permanent Night Vision is a client-side only mod, released under the Creative Commons Attribution Non Commercial Share Alike 4.0 license, and it covers 1.20.1 – 1.21.1 on Forge and NeoForge. EffectTimerHUD is also client-side only and is published under All rights reserved for 1.20.1 – 1.21.8, showing timers rather than granting effects. In-Effect! is the one of these that gives effects permanently, and it needs both client and server.

Add infinite and permanent effects to players with easy config that updates in real time. Also, you can use effects from mods! The effects can't be removed using milk, commands or dying. Open "in_effect-common.toml" file in config folder and add any effect you want.
