1 Year ago, when Nogg-aholic was founded, a group of people with no lives dedicated themselves to finding every last possibility in World of Warcraft, however purposely limiting themselves to clientside modifications only, no 3rd party programs, and no use of emulation.
What you are about to see has been seen before, Air swim and Vertical running. Both are entirely dbc edits, they were discovered by some random noggs back in 1.8 1.9ish.
I have decided to spill the beans on the howto, why? Because I care.
