Swift Spectral Rylak - NOT A REAL MOUNT
While a 'Swift Spectral Rylak' recently appeared in the database for 6.2.1 we can now confirm that it's not a real player mount, but instead just used as a zone mount for player ghosts. See Jeremy Feasel's tweet. Thanks Muffinus for the clarification!
Armory update bug updates...
The Felfire Hawk and Voidtalon of the Dark Star are now showing up on the Armory, so you no longer have to manually add them to your collections. Unfortunately, however, the Brown Horse and Swift Warstrider seem to have vanished from the Armory around the same time and now require manual flagging (see their individual pages to add them to your collection). The Chauffeured Mechano-Hog and Acherus Deathcharger have not changed status and also remain missing.
Terror is coming to the skies of Draenor!
New in Patch 6.2Patch 6.2 is here. It brings a number of important mount changes and additions, including improvements to boar running animations and nineteen new mounts :
Saturated with fel energy, the Deathtusk Felboar is available at Exalted with the new factions Voljin's Headhunters and Hand of the Prophet, for Horde and Alliance respectively.
Two boar mounts are available from another new faction, the Saberon Stalkers. The black Wild Goretusk is available at Honored, for a price of 1000 Blackfang Claws. The demonic, red Bristling Hellboar is available at Exalted for 5000 Blackfang Claws. The claws are obtained by killing Saberon in Fang'rila.
A fel version of the Dread Raven Mount, the Corrupted Dreadwing can be purchased for 150 000 Apexis Crystals from a Order of the Awakened reputation vendor in Tanaan. Requires Friendly reputation.
The shiny green Infernal Direwolf is the reward for the new raid meta-achievement 'Glory of the Hellfire Raider'.
A new model of mecha-suit, the Felsteel Annihilator uses the same animations as the Sky Golem. It drops from Archimonde in the new Hellfire Citadel raid, Mythic mode only.
The Coalfist Gronnling is a reward from a new rare garrison mission.
The Mudback Riverbeast is a reward from a rare naval mission, which is a new feature added in 6.2.
The Warmongering Gladiator's Felblood Gronnling (longest mount name ever) is for PvP Arena season 18.
