Predator

In Oblivion one of my characters is a thief/mage. This means that I spend a lot of time sneaking around with my bow waiting for some unsuspecting shlub to get into my crosshairs. It also means that I spend a lot of time using two key spells. In order to allow me to sulk in the shadows without constantly bumping in to things I have Nighteye, which makes everything visible, but also makes everything blue, and in order to make sure that nobody notices I'm skulking around in the shadows I have chameleon, which makes me not quite invisible, but translucent and blurry. I haven't figured out how to yet, but I fully intend to set my crosshairs to be a little triangle of dots.
