Make your first move

You look her over, considering angles of attack.. And whether to draw it out or go straight for the prize... You are positive of her elven heritage, not just because of her dark silver hair. She has that arrogant bearing to her, so commonly associated with elves and half-elves it could be considered a genetic trait. You are going to enjoy taking her down a notch.

With your superspeed and quick fingers, you'll have no problems with any of the buckles on her armor and can remove anything before she can barely blink. Perhaps you should go for something minor first, like her pauldrons, to show her who she's dealing with and let her mistake sink in.

Or maybe the chestplate and the gambeson shirt underneath. No shame in rushing it a bit. Or perhaps the bra first to tease her. You're quick enough to get some of the other layers out of the way and back in place at the speed of light, after all. You could also sabotage her armor, unbuckling everything so that it'd begin to collapse at the slightest movement.

You reconsider, internally salivating at the prospect. How about everything at once? The shock would be supreme. Your mind goes into overdrive: how about everything, with an extra addition...

Finally, you reply to her challenge. "I accept", you say with a sly smile, and move into action.
