It would be great to have more options to disable some of the gameplay features from this mod like the potions and tipped arrows.

The potion recipes added by Apothic Attributes use a datapack system, so they can be removed via datapack.

The files are here https://github.com/Shadows-of-Fire/Apothic-Attributes/tree/1.21/src/generated/resources/data/apothic_attributes/brewing_mixes

I won't be adding any additional mechanisms to un-register the content; if you would like to make the potions unavailable you can remove the recipes.
