I have not come across any myths about Isis gaining magical powers. However, I know in very early myths, she was sometimes used synonymously with the Sumerian goddess Inana, who tricked her father (king of the gods) to grant her power. If I had to make a guess at an alternate way for Isis to attain powers, it was probably through a partnership with Thoth, the Egyptian god of wisdom, language and magic.
