Elementalist Collector's Items

Anyone know where to find some good elementalist collector's items? I know crystal desert has a few, but are there any other places?

You can get a 20/20 fire staff outside of Ice Caves of Sorrow. You need 5 frigid hearts. Pretty easy to get.

There's an icon or something similar right outside port sledge (Energy +12 with 20/20) using energy storage, it asks for Intricate Grawl Necklace.

There's a Air Staff in Snake Dance (right outside Camp Rankor) (20/20, Energy +10), the collector is asking Frosted griffon wings.
