Origin
Calamitous rogue and binturong

Power
Calamitous rogue: Suspicious moves
This power allows you to essentially "swim" in the air. While sprinting, jump and then click sneak mid air. Then hold sneak and spacebar while looking up and you will fly.

Binturong: Tree Hop
The cooldown is way too short and allows you to just continue jumping mid-air.

Notes
Removing or nerfing of these abilities would be appreciated.
