Well, her armor is definitely at least Amazon make, which probably amounts to "is magical" to an extent. I suspect the answer, insofar as anyone at WB is thinking of it, is "It depends". Most of the powers of the lasso are probably inherent to the lasso. However, her ability to deflect any attack with her bracers is almost certainly *not* a feat of the bracers, but her own innate godpower; she could likely do the same with anything plausibly strong, even if its just a cast iron poker and a ceramic cutting board.
