just 5? Wow...there are times where I get 5 in 10-20 minutes. Then I can go an hour or so without any, but then I'll go and get a bunch in a few minutes again.
I have 10 SoH and I have no idea what to do with them. I could make more imperial silk, but I'm already sitting on like 8, have both epics, and at this point it kinda looks like a waste.
The night is dark and full of terrors...
There is a vendor on the Golden Terrace that you can get other items for them - I leveled up my leatherworking this way.
kunzen camp in northern valley of the 4 winds. just keep killing the 4-5 packs of rockflingers. I get like 2-3 spirits an hour that way.
