Overlord leveling 67+

Hello,



i got my OL to 76 and after i ran out of Vitality leveling slowed down alot...



I did both quests in FOD and SOS, but the mobs there only give around 0.22% each. And the places are cramped.



Is there any other place that a OL can level quicker? Killing mob by mob due to no AOE is taking too long i think.



I also have a 85 Wynn Summoner (other account), is there a way to powerlevel my OL with the Summoner (Mentor)



Thanks for the help.
