Level an Evan 15 levels in 3 days?

35 to 50 can be done in a single sitting anyway. I did 1 to 42 on my Evan in like... 4-5 hours? No 2x involved at all. 35-50 should be manageable in a similar time frame. You don't need magic guard until right at around level 50 anyway. Should be fine without spending any money. (Also, as Stereo said, the quest scrolls aren't tradeable.)
