1.16.3 Custom Effect

[ehbean]

This is my first post here so I apologize if I missed a posting rule, but I've got a question about making a custom potion-like effect. I've got an item in mind, that when used, will give a buff to the player (all vanilla effects). Instead of handing multiple effects to the player at the same time I was wondering if it was possible to make a custom effect that granted multiple vanilla potion effects at the same time? In addition to this, how would I return the empty item to the player in the same way that drinking a potion gives you an empty bottle?

 

Thank you for your time.

I don't think you can as potion effects handling are done in many places, unless you want to simulate all of them.

Override 

onItemUseFinish

and return the stack you want to give to the player, check SoupItem or PotionItem
