Gunslinger Build (Lv. 10-200)

When Nexon gets rid of the Mini Dungeon event, the Golem Mini Dungeon would be a very good place. The whole place is basically a sniping spot, so you'll rarely get hit, and the spawn is pretty nice.

When I went there during the mini-dungeon event, potions were disabled (if I remember correctly). Was that just for the event?

Also, not trying to advertise, but this guide has some decent spots.

edit: We're also getting Magatia today, and it apparently is gunslinger heaven.
