Blast her with a gust of wind

You smirk, and consciously will the staff to unleash its power.

A directed gust of air blasts out from the top of the staff towards the cowering diviner. She shields her face with her arms, and leans into the wind to prevent being blown off her feet. The wind blows hard and unceasing, pushing her back several feet. Furniture in the way topples over.

A chorus of loud rips and tears! The diviner's anklelength robes get shredded in several places and the pieces drift across the room on the turbulent winds. Then, more ripping and snapping, as the fabric of her bra, garter and thong can't take the strain and gets cut apart in the hurricane wind, getting buffeted wildly through the air to settle down here and there in various areas of the room.

You will the blast to cease, and the diviner stumbles, trying to regain her balance. Her hair is toussled all over the place, but once she pulls her hair out of her face, she sees she's just been stripped entirely naked by her own staff. You delight in the sight of her anguished response, as she tries covering herself up while her large boobs bounce about.
