Test your spells on a better subject

If you're going to rely on Obliviate to enter the college, you'd better make sure that last cast wasn't a fluke. Besides, you could think of much better uses for it than mere pest control. Anyone under the spell could have the last few hours, or even years of their life wiped from their memory. This would leave them oblivious to any...liberties you may have taken in that period of time.

Such as ravishing a certain redheaded barmaid just a door away from where her husband slept.

Rock hard at the prospect, you leave your room, shivering with salacious intent.

Haran stood at the back of the cosy little inn, clearing the bar for the night. Her back faced you as she wiped up a days worth of spilled mead off the counter top. You whisper a Muffle incantation as you approach; a simple charm for a peaceful sleep on the road, it ensured you won't be interrupted regardless of the screams that would soon rent the air.
