Both Amber and Cinder have used magic and their semblances at the same time and from the very first episode of RWBY when Cinder whom had already had part of the Fall Maiden's Power (her Tatoo in between her shoulder blades is the proof, as she didn't get that till she taken half of Amber's Powers).
