Step 1. Get the Unusual Egg on Alderaan
There are two reported spawning spots (if you find out about more please let us know in the comments) and the spawning time is around 8 hours!
The first spawn point is at Alsakan Lowlands, bellow the broken bridge. Once you get to the broken bridge you need to jump down onto a tree spanning the void beneath the bridge. Next you jump from the tree onto the nest containing the egg.
The second spawn point is at Kaamos Territory, above the cave entrance. You need to enter the cave and reach its end, than from the top of the mountain drop down into the egg nest.
The third spawn location is in the Castle Panteer. You need MGGS item (the same item that you need for +10 datacron).
Step 2. Get the “Refreshed and Sustained” buff on Tatooine
You need to go to Tattoine’s Judland area. There are structures scattered around the desert. Close to the base of these structures you will see the “Water Access Panel”. Only some of the structures have this panel active (at random). Using the Water Access Panel you will get the “Refreshed and Sustained” buff. (some of you might remember that this same step was needed to get the Magenta Crystal).
