Travenro the Skygazer is the first dragon in the final wing of Veeshan's Peak.
The quickest way to kill Travenro is to run into the middle of the room as a raid and just burn him down on his spawn point.
He will fear on the first attack and later on during the encounter. When feared simply crouch until the fear wears off. You can't cure the fear but it is short duration.
Travenro will constantly knock you back from him, continue to just keep running up attacking him each time he does.
The casters can do more damage if they avoid the lightning pillars along the wall. They can make quarter turns around the room and be able to nuke without being interrupted or knocked around.
This fight is a lot of fun and very easy. Travenro updates the mythical weapon for warlocks.
