Fenyx the Horseman Achievement in Immortals Fenyx Rising
Fenyx the Horseman25
Tame all mounts.
How to unlock Fenyx the HorsemanThere are a total of 25 mounts that need to be tamed for this achievement. The story will teach you how to tame your first one, but the rest all need to be hunted down. Of the 25 mounts in the game, nine of them are epic mounts. There is no difference between taming normal and epic mounts. The only difference is that normal mounts are found in small herds, whereas the epic mounts are located by themselves. Also, taming your first epic mount of the nine will unlock Oceancookie (15G).
