655% XP Boost, level 61-85 in two hours. Patch .

Leveling from 61-85 in two hours with Potion of Ancient Knowledge. This is my first attempt to use the combination of Recruit a Friend, Potion of Ancient Knowledge, heirlooms and guild perk to see how far I would be able to get. On a side note: The overall time it took to do it was about four hours because there I logged my character out and was looking for the best quests in Northrend to do so the potion would give me as much xp as possible.
