Last time, Adam disintegrated the Spider Droid with one clean cut that also cut through the cargo and the forest behind. He also told Blake to move suggesting that his attack is so powerful it could also kill Blake had she been hit.

I believe Adam's Semblance allows him to cut through anything and everything, including Aura. Another thing to notice is that before he does it, he used his blade to stop Blake's bullets and like when he absorbed the Spider's laser, his blade and his clothes were also shining. Maybe Adam absorbed Blake's bullets which allowed him to use his Semblance but since these were just bullets and didn't have much power, he only managed to cut Yang's arm. If he had charged it even more, he could have completely erase her. Yeah, I'm pretty sure that it was due to Moonslice. But unfortunately, we can't be 100% sure right now what exactly Moonslice's function is, other than "Block attacks to absorb energy, then cut the thing."

I kinda wonder if Moonslice is capable of cutting straight through any kind of armor - Aura, a robot's metal plates, a Grimm's bone plates, actual armor, etc.
