Her semblance is actually completely unrelated to her fighting style, though it helps. It's a luck based one; sorta like Qrow's but not leaning to either good or bad luck. And it starts small but escalates the longer she has it active. It is also manually activated, not passive like Qrow's.

Basically her semblances increases the likelihood of something that was already set up happening; like a tree that has weak roots falling over when she activates her semblance, or a decent hit doing much more damage due to a lucky strike to a weak point. She can't pick or choose what happens, she just rolls with the punches.
