Drizzt Do'Urdon had been watching this female since she came to the pools.  His mission had been to capture one of the mages for questioning after the diversionary battle. She looked like a likely candidate. She had been swimming in the pools for a while and she hadn't noticed she was the last one there. As many elves sometimes can, she seemed to have lost track of time as she relaxed.<br/><br/>He invoked the the castings of his silence spell. Then he chose to go with a blur spell since it was dark enough that a blur would most likely be sufficient and it was much less draining than full invisibility.  Soon he had padded down to the water's edge and waited for his target to comeout of the water.  He readied a sphere of silence and also his lead filled sap for knocking her out.<br/><br/>After some time, when she had finally realized that she needed to get out of the water, he waited until she bent over for her dress and leaped into action. The sphere of silence was cast, complicating her spellcasting, and he leaped out of the shadows swinging his sap at the back of her head.
