Only Subscribers can use Mounts. A character must be Level 60+ to ride a Mount. Mounts are purchased by buying a Mount Certificate from the pet market in Bonta at [-36,-56] or Brakmar [-32,37], or by exchanging with another player. Beware! You will not be able to ride your Mount unless its conditions are Mountable = Yes, Wild = No, Energy > 0 and Maturity = 10000. Also, certificates expire so be careful not to buy an expired one. Once all these conditions are satisfied, take the certificate in the inventory of your Level 60+ character to a public Paddock such as the ones in Bonta and Brakmar. Click on the Paddock gate to get the option to equip your Mount. Once you have it equipped you will still not be riding it, click the dragoturkey head icon (default keyboard shortcut d) to look at your equipped Mount, then click the first button to mount/dismount it.
