Ive actually never used this glitch.
For me, the joy of the game is in the journey, not the destination. I tend to start a new character when my old one is 'done', I just get itchy for a playthrough where I can build my character just as I want. Start out weak, end up strong, but being strong doesnt hold that much interest to me, its more the road to it that I find enjoyable.
So Ive always thought: Why take all the jopy out of the game by starting as a level 81?
Different strokes for different folks I suppose.
Once I did actually want to use the glitch.
I needed five more levels in enchanting but didnt want to grind. I had kept the Infinium by dropping it after the quest, because I wanted to display it in a bookcase.
Well, just my luck, the one time I decide that five more levels in the magic skills wont be detrimental to my playthrough, the bookcase had
glitched and it had eaten my Oghma Infinium!
So not only did I not get to use it when I decided Id try it once, only for five extra levels, I also had to restart that character as such glitches invariable keep annoying me the entire playthrough, I just cant live with the fact that I had an awesome trophy but my bookcase ate it.
