Custom Mob Potion Effect

This is a powerful Minecraft mod for customizing a mob's own potion effects, as well as potion effects applied by its attacks, on death, at low health, and when it is attacked. It can meet your editing needs and most of your design requirements, and is currently only available for Minecraft 1.20.1 Forge

This mod provides a visual editing page that players with administrator permissions can open by pressing the [K] key. In this panel, you can select the card corresponding to the mob you want to configure and adjust the relevant settings, etc(Based on the introduction to the latest version 2.0.0 of this mod):

The mob editing interface allows you to choose whether to display the mob's own potion effects, freely add potion effects to the mob itself, and also add potion effects applied by the mob's attacks (it also supports triggers such as when the mob is attacked, persistent auras, on death, etc.). You can also freely edit the levels, durations, and other properties of these potion effects, as well as their potion effect chances. Once editing is complete, the changes take effect immediately in your world, so you can preview the results very quickly.

In the potion effect editing and adding interface, we have also added helper features, such as Favorites (right-click a potion effect to add it) and Recently Added, to help players edit and provide a better experience. We have also added categories and related search functionality.

In addition, editors can also edit the potion effects of players themselves, with the same related features and mechanics, helping players better enjoy the custom mob potion effect editing functionality.
