Use your mind...

Unlike your body, your mind has never let you down. Just because you are a little bigger it doesn't mean you're the biggest. Better to play this safe, figure out an angle you can work. You eye the witch up again, looking for some aspect you can exploit. Hm...Her garb is unusually minimalistic for a hero (and exceptionally unrevealing for a heroine): A simple black robe, falling loosely over understated curves all the way to her ankles, where black pointed boots peek out. The tall witch-hat is the only other garment you can see, she's not even wearing the multitude of enchanted rings that practically define a heroes outfit. This all adds up to a very confusing picture and not one you like at all.

"(Sigh) Well monster? Are you going to make your move?" You freeze as she stops and turns to look at you. Well...you're in it now. Might as well roll with it. Anchoring yourself on the riverbed so you don't drift off, you raise your head slightly out of the water. Looking as harmless and bedraggled as possible, you bow your head low, pitching your voice higher and adding a raspy edge, "Good evening fair mistress, I mean you no harm..." She raises an eyebrow but doesn't comment. After a moment you continue, speaking the words as fast as you can think them, "...I was enraptured by thy..." Uh.... If you said beauty, she might attack you on principle. She had the austere look of someone who doesn't take shit. "...aura of power." Her mouth quirks to the side slightly. Nailed it.

"And what, pray tell, do you seek by an audience with me monster?" That...was a very good question. You'd been hoping to study her a bit longer, take your time figuring out a plan, but you need that plan RIGHT NOW. Well, let's hope you're good at bullshitting...
