Like any other Craglorn skyshard, this one is found inside a Group Delve – Serpent’s Nest in this case. You can find it in northwestern Craglorn, west of Trial: Sanctum Ophidia
There is more than one group you have to skip/kill in order to reach the skyshard’s location. Shard is located at the central part of the cave. You can reach this point of delve when you turn left at the crossroad that takes you to the last cave room in southwestern Serpent’s Nest. Skyshard is defended by couple of veteran level 13 Snakes and one Troll.
