Clare avoided being absorbed into by retaining her ego, it seems. Maintaining her sense of self prevented her from turning into a mass of nothingness.

If it was a power that got her out of it, I'd call it willpower, as opposed to physical prowess which you seem to be hinting.

Of course, she owes a huge thanks to whoever that voice was.
She also shared a lot with the entity right before it awakened:
-Memories, some of which could include a lot from the organisation hidden agenda
-Maybe fighting techniques or knowledge
Everything both Claymores knew prior to this awakening.

Clare has always been some kind of powercell getting power from others gaining former #1 flesh, then an arm from another powerful claymore... and now memories from 2 strong fighters.
She's an hybrid whose level is hard to evaluate, but could be enough to get out alive from any situation.
