Grey Warden Cache

Infinite Experience Bug
Upon entering the Wilds to obtain the 3 vials of Darkspawn Blood and the Grey Warden Documents, do not loot any darkspawn you kill. Head to the ruined Grey Warden tower, converse with Morrigan, speak to Flemeth and you will be returned to camp automatically. Speak to Duncan and tell him you have the documents, but not the blood. You will receive quest completion experience. Repeat this process, speaking to Duncan over and over until you reach the level you desire. When you are finished, return to the Wilds, looting the darkspawn for the necessary vials of blood (and complete any other side quests the Wilds have to offer).
