Wait, if you have that quest item and click the depleted crystal it says "recovering"? Or does it say recovering when you're doing the quest on another crystal?
Now, what vendor is that from, unless it's a quest item.
Actually, Knotor says it's a "mission item." http://knotor.com/items/181005-crystal-mining-equipment
Doubtful. I also looked at 273 on hoth near the glacial stuff with the volcanoes since 273 is the melting/freezing point of water. Did some mountain climbing there and found nothing.
There is a big door you can't interact with near some lost tauntauns. Also found a Legendary Wampa that drops orange items like 3 times in a row if you wait on respawns, then he won't drop anything.
