A few more general guidelines for the rares before we get into the different mounts: they do spawn fairly quickly if they are up. Most rare spawns on Argus are up for between 3 and 12 hours before despawning for a certain amount of time, so don't worry if you don't manage to hit it before a group kills it; you will get a new chance in a few minutes. This also means that if a rare is not up within a few minutes, you better not spend your time waiting; instead do something else and check back in 3+ hours. The drop rate seems to be around 2.5 % for each daily kill, and there's a total of 4 dropable mounts, so you will get a new once pretty often if you got a few alts that do the rotation.
Checking for the rare spawns is actually really fast, and should really just take between 5 and 10 minutes for a complete route.
Below you will find a map for each zone, with numbers on them. Check the numbers against the table below to see the name of the rare + what mount it drops. Happy mount farming!
Mac'Aree rares that drop mounts
2: Kaara the Pale - Fel-Spotted Egg
3: Venomtail Skyfin - Lambent Mana Ray
4: Sabuul - Fel-Spotted Egg
5: Wranger Kravos- Maddened Chaosrunner
3 of them are pretty close to each other, but you've got to do some traveling to get to Skreeg. Wrangler Kravos should only be a short ride from the other 3, which are quick to check.
Antoran Wastes rares that drop mounts
1: Blistermaw - Crimson Slavermaw
2: Varga - Fel-Spotted Egg
3: Houndmaster Kerrax - Vile Fiend
All of these are also really close to each other, so checking if they're all up should only take a few minutes.
Krokuun rares that drop mounts
1: Naroua <King of the Forest> - Fel-Spotted Egg
Only one rare mob that drops the egg here, but it could be worth to check if you are doing a world quest or an invasion point close to it.
What's in the Fel-Spotted Egg?As you can see from the tables above, 4 of the rares drop a Fel-Spotted Egg instead of a mount. This egg has a 5 day timer, so you have to wait for 5 days after looting it before it will open, but once it's hatched you have a chance to get one of the following:
- Scintillating Mana Ray
- Felglow Mana Ray
- Vibrant Mana Ray
- Darkspore Mana Ray
It can also crack into a few pets, or simply thrash. You can get a mount you already own, so getting all four requires a good amount of luck. The drop chance of the eggs are around 25 %, and in contrast to the previous eggs that functioned like these, you can indeed have more than one at a time! So don't stop killing them just because you already have one in your inventory, because there's no limit to how many you can keep at the same time.
