Wow there's a ton of really unique and interesting mechanics put into here! Just got one question, since it ties in so closely with a lot of the mechanics.
Is the only way to increase the "rise of jaddeth" level the one step in birdsong? I just feel like since a normal game of root only lasts about 7 rounds, the game may end before you get to your really juicy swing turns! Also those few turns at the beginning are gonna be rough in each battle you're in, since you're never ever gonna deal rolled hits.
At least that's how I'm reading it, if it works differently please let me know! I think it's a super unique concept and I'd love to play a game as and against them!
