As for weter the gods would still have there "skils" without their powers I don't know
I have always preceaved skuld techincal abbility and urd potions as exstentions of their powers, manifistations if you will, as mere mortals of gods inhabiting the eath it meraly how the powers are preceaved by our eyes
in the movie bell singd and revitelises a tree, I would really like to beleave a "mere" song could do such a thing but we know that she is casting a spell, this becomes more clear when in the end they save earth by singing, aka writting a program.
