This is a video dating back into Cataclysm. The guild was grinding Alterac Valley for HKs and Training, doing the usual Blockades when we discovered that you could still summon Lok'Holar. So we handed in the blood and done the summon. Then we baby sat the beast until he was big enough to do some damage.
This was from Cataclysm 2011 so i am not sure if you can still summon him. Video complete with Guild Teamspeak from the time. Video made by Zwarn.
(To any old skewl Vanilla players who watch this, i know this is not as good as it use to be but sadly the reinforcements limit what you can do with him.)
