NPC Loot Mounts
Most mounts in this category may be found as low-chance or extremely-rare loot after killing enemies, or in loot caches after defeating bosses. A few unusual ones entail farming eggs that may randomly hatch into the desired mount.
Island Expeditions are a new type of timed scenario introduced in Battle for Azeroth, in which you compete against the opposing faction to gather resources. After completing the scenario there's a chance to loot special reward items, including a rare chance of mounts. There's a PvP and non-PvP mode for these scenarios, but we're currently unsure whether both offer mount rewards. If it turns out to be just PvP, we'll reclassify these mounts as PvP only. For detailed information, see Wowhead's Island Expeditions Guide.
World Boss or Rare Drops
Rare or special NPCs around the world that have a chance of dropping a mount. Many of these are extremely low drops, though others are guaranteed. See the individual mount pages for more information.
World Boss or Rare Drops - Fel-Spotted Eggs
Fel-Spotted Eggs from Argus have a chance to hatch one of four possible mana ray mounts. The eggs are a chance drop from specific rares on Argus - Varga in Antoran Wastes, Naroua in Krokuun, and Sabuul in Mac'Aree. One looted, an egg takes 5 days to hatch and you may hold more than one at once. The mana ray mount that hatches is random, and it's possible to get the same mount more than once, as well as a chance of companion pets and junk items.
Random World or Zone Drops
These involve farming regular, hostile NPCs in a zone for a low chance of getting a specific mount.
Random World or Zone Drops - Cracked Primal Eggs
Primal Eggs are rare drops from devilsaurs, direhorns and skyscreamers on the Isle of Giants. After three days a looted egg will hatch, with 100% chance of looting the Reins of the Black, Green or Red Primal Raptor. The mount is random and it's possible to receive the same mount more than once.
