I'm happy with all those changes.
Skin Graft should have been a source skill from the beginning; limiting usage by source points makes more sense than "one per encounter".
Bless is very strong in the sense that it converts a surface, regardless of its size, to something that does the opposite. All skills to create cursed surfaces in EA also require source points. I think it's only fair if it's a source skill as well.
I'm not a fan of stunning going through an intermediate status. Water is fairly weak on its own, what's good about it are combos with air. If we need to do through extra steps it might not compare favorably to fire or earth.
