Ars Flora

This datapack requires Botania, Ars Nouveau, Create, Blasma Tech, and Starbunckle Mania. By putting the mana/source in the Create Mixer and Basin as well as their catalyst (source gems/mystical flowers) you can convert either sources of magic into the other.

The conversion is 1:1 but the catalyst are 5:1. You need 10 mystical flowers to convert one basin full (one bucket) of source into mana, and you need 2 source gems to convert one basin full of mana into source.

(Yes, you can use this in modpacks)
