The Mechanostrider is a mechanical bird that has a cannon ( Critter Destroyer 9000 ) instead of a head and that is why it is one of the most feared mounts. You can purchase this mount for 100 Champion's Seals from Rillie Spindlenut in Silver Covenant Pavilion of the Argent Tournament. If you are having troubles, just order our WoW Gnomeregan Mechanostrider Mount Boost service and our team of highly professional boosters will do it for you.
