There are rares that have a chance at dropping the egg, but let’s not get ahead of ourselves. We should first start at the beginning of how to obtain this wondrous egg. Keep in mind, the egg is not at a 100% drop rate, and there is no guarantee as to what will be in it when it cracks. The first thing you will need to do if you have not done it already is the Argus Campaign quests so you can get to Argus. Keep in mind, that you must complete the Broken Shore Assault in order to get to even the Argus Campaign, so if you are like me and have not worried much about it, be prepared for a task at hand.
There are four rares that you can kill in order to obtain this egg: Kaara the Pale, Sabuul, Varga, and Narou. Though these beasts will not be up every time you head there, it is still worth a trip to see if they are. You can kill each of the rares once a day for a potential shot at getting this Fel-spotted egg. The rares can be solo-ed, and once again depending on your gear may or may not prove to be a challenge for you. Each one is spread out on four different areas in Argus. Narou is on Krokuun, making her the first that you can access, as this is where the Argus campaign takes place.
The egg does have a 40 percent change to drop off all the rares. Sabuul can be found on Mac’aree, coordinates are around 44.8, 50.6. She will be around this area. It is important to note that there is a world quest to kill these mounts that drop the egg, but you do not need to have the world quest in order to have a chance at getting the egg.
