Fledgling Oliveback
Drops from Cracked Egg. Always in its brother's shadow. Flying type. For those without coordinates: Start at Illadari stand and run Northwest along the road until you hit an area with banshees in it.
The Fledgling Oliveback is a wild battle pet found exclusively at the top of the Rhut'van Divide mountain in Azsuna, and counts toward the Broken Isles Safari achievement.
Guide awaiting review
Reach the Trailhead
Head to the Nor'Danil Wellspring at 39.1, 32.9 in Azsuna. The trail entrance to Rhut'van Divide begins here — on the map it sits roughly where the 'IN' appears in 'WELLSPRING'.
Climb to the Summit
Follow the path northwest and keep climbing to the top of the mountain. Along the way you will encounter Grizzly Squirrels and Olivetail Hares, with Fledgling Olivebacks appearing as you get higher. There is also a back trail to the top starting at 43.12, 18.96 if needed.
Find Spawn Points at Summit
Fledgling Olivebacks spawn across several points near the summit, including at 42.23, 23.58 — at 41.35, 22.87 — at 38.4, 24.22 — at 41.59, 25.32 — and at 41.54, 20.92 in Azsuna. These spawn points are shared with Olivetail Hares, Grizzly Squirrels, and the much rarer Fledgling Kingfeather. The Fledgling Oliveback will only appear as a primary battle pet, never as a secondary.
Avoid Jumping Off the Cliff
Do not jump down the far side of the mountain to reach a spawn near 41.45, 19.07 — doing so will cut off your path back to the main Fledgling spawn area. If you do go over, a glider such as a Goblin Glider Kit or Demon Hunter glide can carry you south to safety, but you will need to re-climb from the trailhead at 39.1, 32.9.
Force Oliveback Respawns
If you cannot find a battleable Fledgling Oliveback, defeat the other non-Oliveback battle pets in the area. Doing so has caused critter Olivebacks to respawn as battleable ones.
Tips
Fledgling Olivebacks only appear as primary pets and cannot be encountered as secondaries in other battles.
