not sure if this is known or not but i didnt see it on the wiki in the bugs section of whirlwind sprint (so i added it lastnight). basically if you use whirlwind sprint (number of words used doesnt matter) and right as you are boosting forwards you open the wait dialogue and wait for 1 hour, then as you are coming out of the wait dialogue you mash the shout key, you will repeatedly boost forwards without actually shouting the words or consuming the cooldown. going into the falling animation kills it and you cant turn the camera, but even after its killed, its still off cooldown unless you keep mashing after its killed and end up triggering a "legitamate" shout
