Hey,
I <p>Hey,<br><br>I don't know if this is the best location but noticed Penguins and Badgers drop them. I looted a ton of all the colours in less than five minutes in the Penguin/Badger spawn west over the bridge of Svargrond city. I started from the ice levitate wall north (the route into the mammoth boss or man in cave) and went south to the end and repeated, you come across too many Penguin to count and they are all 1 shot. I will upload a picture soon to highlight the example.
