Thankfully, summoning the hammer is one of the easy tricks, and skill she has, just not experience.
She also, thankfully, has durability. She can't dodge like her opponent, but she can take Sentinel fire. Even Wakandan arms don't measure up to the most advanced killer robots. Still, it hurts.

That fact, mostly, just makes her angry. Hammer in hand, she dives after her opponent, trying to ko him while he's dazed. She'll deal with the gunfire next.
