Geez, you really have to open Adventurer's Handbook -> Enemies -> Treasure Hoarders. And press navigate. It will show you all necessary locations.

Guys if you want to search location use adventure handbook and they will respawn every 11 hours

this was useless i was trying to ascend a character of mine and i couldnt find **** of where the treasure hoarders could be found update this article or delete it

please update this article

Seriously? Who the hell made this. Don't call it freaking "Treasure Hoarder Insignia - Location & How To Farm" when you don't tell us about any of it!

This neither tells us the location, nor how to farm it... Might as well call it "Treasure Hoader Insignias Sure Do Exist"
