Use or Sell Runestone
This is a Daily Quest in Ulfheim.
Talk to Kaiser, who is standing at the Southwest entrance/exit of Ulfheim, and ask him about "runestone".
The Ulfheim Runestone drops as loot from the humanoid barbarians (particularly the spellcasters).
The Ulfheim Runestone can be utilized in either of the following ways:
- Use the runestone to activate one of the teleport pads - when the Ulfheim Runestone is in your inventory, clicking on the "Arcane Panel" of a teleport pad will teleport you another pad. If you teleport from the lower pad to the pad at the top of the mountain, you can bypass many of the wave battles (thus, it is a shortcut that gets you closer to where the White Dragon spawns).
- Sell it to Kaiser - Kaiser is at the Southwest entrance/exit of Ulfheim. If you ask him about "Runestone", you you can give him the runestone and he will "pay" you gold and 40,960 experience points (or 81,920 during double XP).
