Once you can reach the Troll town, head out left from the teleportation (troll town) place. When you reach a fork in the path, take the left route and look carefully for a shining bug. It is well hidden in the bushes. Rocks are also blocking your view. Kick this golden bug and fight it. It is very weak and gives 1exp however, it gives you 8888 Dagols. Do this every day (sleep and it respawns).
