Similar to another post in this similar quest line. This one is phased and you can do it if you've completed the previous quest where the mob then becomes invisible.

LVLING/FARMING RESTED XP by killing Excess Power mobs

zone: Azsuna-Legion
class: better for classes with max 15 sec CD on interrupt/kick spell

choose Azsune questline from map strike point in Order Hall (optional)complete questline in Illidari Stand (part 1 of achiev Azsuna Matata is Behind Legion Lines) complete quests at Azsurewing Repose & quests of Runas the Shamed at Ley-Ruins at Zarkhenar and flyquest back to Azsurewing Reposecomplete 2 quest and u will get Hunger's End quest (DONT FINISH THIS QUEST)
Hunger's End quest is to kill Orbyth and Ael'Yith

Kill Orbyth and start farming Excess Power mobs from Ael'Yith which are spawn with Wild Magic Wild Magic spell every 20 sec (4 of them)
Using this tacts atm:
- nuke down Orbyth and Ael'Yith jumps down

- position yourself facing back to the wall/stone in front to the Ael'Yith

- He begin casting Energy Expulsion, u can position yourself (and standing still) so u wont get knockback

- after that he cast Energy Drain spell IMPORTANT that u interrupt it (it is long cast/channeled time + annyoing and so u can maximize xp in shortest time)

- after that he cast Wild Magic which spawns Excess Power to random location (cuz u are back to wall/stone all spawns at random location will come infront of u, they wont get behand your back)

- single target tho...
