Empowered Enhancement Stones

Im on the West server and the price for these stones is through the roof... 23k per stone, so I wanted to know if anyone here wanna come along with me to farm a few stacks of these. Leave is a Private Message and we will work something out. I have a few places that we can farm at and get a good amount.

Someone is upgrading weapons at the moment. Wait a couple days and they should drop to 5-8k or farm them for yourself.

Are empowered source rich in Hero mode? I don't know place other than hero can easily get these stones

Rescue or below drops empowered. Rescue preferred.

I haven't seen one under 18k >.<
I wasted so much money getting my swords to +9 >.>
