This Havoc Demon Hunter is using the green warglaives from the Demon Hunter introduction questline. The set bonus on these weapons was missed initially during the stat squish and gave 500 AP when fighting demons. This was hotfixed the same day as the parse or the day after to 50 AP, which is more in line with expected values. I tried flagging his parse for exploits, but it came back negative.
