Hi. I'm currently using the potion-blender mod (1.20.1) and I was wondering if it's possible to add a levitation potion to the custom cauldron recipes.

The potion look like this in command line:
/give @p minecraft:potion{display:{Name:"{"text":"Potion of Levitation","italic":"false"}"},CustomPotionEffects:[{Id:25,Amplifier:30,Duration:50}],Potion:"minecraft:water",CustomPotionColor:7697781}

Thank you for create this mod is so fun!

Adding custom recipe is done trough datapack (you can look up a tutorial like the one for create it work basically the same). I also put a few recipes examples on the wiki.

However, prior to 1.2O.5 it was impossible to add NBT tag to recipe output in datapack and therefore impossible to add potion effects. You can either use a mod to add NBT tag in recipe or update minecraft.

Hope i helped you, feel free to ask if you have more questions :)

I installed the NBT recipes mod. Works perfectly now.

Thanks for the help!
