Anyone know how long it takes them to respawn? I've been waiting a good 20 minutes to farm some more of them...
This post is extremely helpful.
Patch can be found on an island right above the Treacherous Depths text on the map of Mount Maelstrom
Still took me a while to find. The island can be found nearly directly South of the Oxbow Island Waypoint, and West of the big weird structure in the middle of the bay.
Northeast of Straits of Devastation : Northeast of Plinth Timberland Waypoint
Several can be found Southeast of Bramble Pass Waypoint in Straits of Devastation.
