Quick Question: Are the evolutions from Ultimate Magic still valid for Unchained Eidolons?
I normally play a sorcerer with a Voidwurm Protean as an Improved Familiar. I've been considering respecting using Variant Multiclassing into Summoner to pick my Voidwurm up as an Eidolon instead.
This would really only be feasible if some of the Ultimate Magic Evolutions like Basic Magic, Minor Magic, and Major Magic were still available. As far as I can see, there's pretty much no way to grant magic to an Eidolon using the Unchained Evolutions, aside from energy damage on attacks and as a breath weapon.
