Herb magic for Mythic Bastionland [WIP]

Buildings are people made the excellent post Cleric spells are Herbs and I want to use it for Mythic Bastionland. 

Here is my version adapted (with some modification) to the Mythic Bastionland ruleset. 

(So far I've only finished the mechanics on the level 0 common herbs, will add level 1-4 later. Descriptions of the herbs are still in progress).
