In Northweatern Westfall, running along the cliff, there is a lone windmill with a tiny shack at its base. It is surrounded by 6-7 Defias mobs, levels 12-13.

Whats the catch?

They respawn immediately. Get the drift?

WHAT LEVEL YOU SHOULD BE:

I would suggest 24+, however I was 33 when I discovered it, and it is still extremely useful when you reach 60.

WHAT TO USE THIS SPOT FOR:

1) Grinding/Maxing new weapon proficiencies...

You should be level 20 or above to do this by yourself.

You want to go to north Darkshore (not Darkshire), in the Ruins of Mathyra. Follow the road towards to the Ruins, when you see the entrance, make a right turn hugging the boundaries of the tower. Pass by the Myrms and keep on going to the southeast until you are on the outskirts of the Ruins of Mathrya zone, where no monsters spawn.

To the north of this location, you'll see a few lingering Myrm well spread apart. Go towards them. You are looking for Cat Figurines in this area. These Cat Figurines are worth 1s each, and spawn just as you pick one up. In this area just outside the tower there are 4 Cat Figurine respawn locations. If you search around the area between the tower and the Mine-Dungeon entrance (be sure you search in the areas where they are lined up perfectly ) you'll find the Cat Figurines.
