Profession mounts

Profession mounts that are available from most of the professions in the game, whether primary or secondary.

Alchemy

Alchemists can use archaeology to find a recipe that will teach them to create [Vial of the Sands]. The vial teaches players how to turn into a Sandstone Drake, a flying mount that allows for one passenger.

Engineering

There are two flying machines that can be crafted and used only by engineers.

Flying Machine (airborne)
Flying Machine (landed)
Turbo-Charged Flying Machine

Engineering also allows a character to create a faction-specific ground mount that can carry one passenger. Unlike flying machines these bikes can be used by non-engineers. Obtaining this mount awards the achievement [Get to the Choppa!].

Mechano-Hog

Engineers can learn to create a rocket mount based on their specialization, which can be sold to non-engineers. Gnomish engineering can only make the [Geosynchronous World Spinner], while Goblin engineering can only make the [Depleted-Kyparium Rocket].

The [Brinedeep Bottom-Feeder] can be purchased for 100x [Drowned Mana], which the mana can be fished from Margoss's Retreat.
The [Darkwater Skate] can be purchased for 500x [Darkmoon Daggermaw], which these fishes can be caught in the Darkmoon Island ocean waters.

Jewelcrafting

Jewelcrafters can learn to make five jewel panther mounts that can be sold. The first four are the [Jade Panther], [Sunstone Panther], [Ruby Panther] and [Sapphire Panther]. The first four are then themselves used as mats to create the [Jeweled Onyx Panther]. This means to have all five, the first four are created twice, one set to be mounts, and another set as mats.
