Alliance Three Is a Lucky Number
Bring Ari 3 special gifts. These gifts can be found on powerful enemies in dungeons.
Description
Ari is much more than she appears, you know. She was once one of the most powerful archmagi on Azeroth and a member of the Council of Tirisfal. Unfortunately her mind was badly damaged and she has not left the Hall of the Guardian since. She must like you very much to have given you a gift. If you bring her something special in return, I suspect she will surprise you. She prefers things in threes.
Rewards
You will also receive:
These items will drop off of any of the end bosses in the dungeons of Legion. The order in which they drop are random. Simply queuing up for random dungeons and completing them (3 of them) will get this quest done for you.
