This is the third mount run video. Zul'Gurub is a 20-man level 60 raid located in north-western Stranglethorn Vale. The closest flight path for the Alliance is the Rebel Camp in Stranglethorn Vale; the closest flight path for the Horde is Grom'gol Base Camp in Stranglethorn Vale.
There are two mounts in this instance: the Razzashi Raptor and the Zulian Tiger. The Raptor has a 0.9% drop rate and the Tiger has a 0.8% drop rate. I've only seen the Raptor drop once and I've never seen the TIger drop.
This is my first mount run video. Karazhan is a 10-man level 70 raid located in the southern part of Deadwind Pass. The closest flight point for Alliance players is Darkshire in Duskwood, and the closest for Horde players is Stonard in Swamp of Sorrows. The Fiery Warhorse Reins have a 0.7% chance to drop from Attumen the Huntsman. To summon Attumen you just need to attack his horse, Midnight. Once either of them is down to 25% health Attumen will mount Midnight and be at full health. Kill him, then loot him and see if you got lucky. I have never seen this mount drop.
I will be releasing videos of all the mount runs in game right now over the next couple weeks. The next one should be the two mounts in Zul'Gurub.
