When Adrianna Tomaz became Isis, she has other powers that Shazam and Black Adam don't have like telekinesis and controlling other elements than lightning.
Her powers stem directly and only from the goddess Isis. The comics portray her as more of a nature goddess, or a goddess of life in general, so she has a strong connection to living things and the natural world. She could create and manipulate plant life in 52. Her powers were pretty vague overall, as most comics tend to be.
