The Angry Scytheclaws is the 6th quest in the quest chain. It begins and ends with Sergra Darkthorn.
Kill Sunscale raptors and collect their feathers. Use the feathers on the 3 Scytheclaw nests. Return to Sergra Darkthorn in the Crossroads.
Now, <name>, the hunt deepens. Now you must defeat your prey, and then find your way to its lair.
Hunt the sunscale raptors to the south. Slay them and remove the feathers they wear. Place the feathers on the scytheclaw nests southwest of the Stagnant Oasis. Show their brethren you do not fear them!
Have you been to the nests, <name>?
So you've been to the nests and placed the feathers of your prey within them. That took a fair portion of courage, no doubt about it.
Do you feel a little tougher, <name>? Because you look tougher now then when you first came here. I guess the Barrens is doing its job.
Head south from The Crossroads until you get to the bridge at the small ditch. The nests will be off to the east, next to a small hill with kodo bones next to it. The you need drop off the Scytheclaws in the area. Each of the nests contains a glowing egg corresponding to the nest's color (yellow, red, blue). You'll need 3 feathers for each of the 3 separate nests. If you need additional feathers, the Raptor Grounds contains many, and can be found by simply following the small ditch east to the mountains.
The three nests are not far from the Gold Road [52, 46].
