Potions - all themes

[shailalias]

Ideally, a cauldron could be used to create all potions. The obvious downside is they can only have a max of 2 ingredients. The alternative would be to use a cauldron to give plants/herbs "magical properties" and use those in cooking recipes. The obvious advantage would be that it can take advantage of the upcoming Json Assests mod, and they could each have special buffs.
