This may be a hard ask, but could the shaman traits be spread out over 2 of the Mutation slots? You have the Shaman Feathers and the Shaman Mane in the same slot and that's a real shame honestly. I also feel like the Talismans mutation should be separate from those 2 as it would go together with them so well. If you aren't sure how the collectors and general players would feel about it maybe host a poll to see if other players feel the same and would be on board with it first.
