User blog:FrostEternal/Tenguru, The Wind's Edge

Passive: Wind Walker:  When Tenguru is moving towards the Enemy Nexus he starts gaining Movement Speed (cap of +70), if Tenguru turns away from the enemy nexus this ability is negated until he is directed towards the enemy Nexus again.

Q: Avian Assault: Tenguru lashes out at enemy champions dealing Physical damage. Note if the enemy Champions is afflicted with FeatherStorm then the cooldown on Avain Assault is refreshed.
