Rock crabs suck for afk. :L

I've never been to the dags, so I would recomend the axe hut.

Just bring a weapon, rune kite, legs and plate with an invent full of lobbies and play a small online game in the corner blocking the screen, keep the menu to your stats so you can check your health and glance at the map to see if any pk parties are coming. Tbh it's fun trying to dodge and annoy the pk'ers. :>
