In Thousand Needles is a cave that contains many level 28-30 Harpies. These have a fast respawn and drop good trash items that you can sell at the merchant for gold.
Where is the cave?
In the south of the Thousand Needles zone there is a cave called the Roguefeather Den. This can be reached via a path on the rock face.
Both inside and outside the cave are the following harpies:
Due to the fast respawn you should be extremely careful in the cave!
Why is the Farmspot worth it?
For example, you get 8 silver for a colorful feather bush!
You should always sell green or blue armor/weapons in the auction house, because on HC realms the demand for any improvement is very high!
