this all sounds fantastic. The advanced power system feels like the extra kick you would get after a while in an RPG. Though I do think the fact that players are able to get more than one Soul trait when human is a little…Maybe… overpowered? The whole thing with the human soul humans in Deltarune in Undertale is that they mostly have one singular soul trait. I don’t think multiple soul traits is a terrible idea but it feels like to me that being able to get a lot/like maybe all the soul types is a little overpowered. (I might’ve read it wrong. There could be the cap at like two or something. I don’t know. Don’t blame me please.)
Edit: OK so the extra Soultrait thing only happens at LV5… so yeah that makes it feel a lot more balanced actually additionally, I also like the fact that you have an option for you go all in on one certain soul trait and get an advanced power, or you can also branch off into a multi traited person and have two base power soul traits
