Lord Ieuan Amlodd is the leader of the Amlodd Clan of elves. He can be found at the Amlodd Clan district in the north west part of Prifddinas off the western path. He is clad in blue robes as well as varying animal pelt and bones. His outfit is styled around the skills in which his clan is specialised, Summoning and Divination. He also gives access to a summoning shop and will swap summoning pouches for spirit shards at the same rate as Bogrog. Having completed the Hard Tirannwn tasks will make Lord Amlodd swap pouches for roughly 10% more shards.
There is currently a bug where the interface and chat messages will still show the old return values after completing the Hard Tirannwn tasks.
After the Prifddinas coup orchestrated by Lord Iorwerth, Lord Amlodd hid in exile, waiting for the time when his brethren would strike a counterattack to reclaim the city, as most of the other clan leaders did. Amlodd chose to reside in the Spirit Plane.
During the events of Plague's End, the adventurer is tasked with gathering the hiding clan leaders together. Lord Amlodd is returned to Gielinor when the player creates an Amlodd Pouch and uses it to summon him from the Spirit Realm. Amlodd shows that he greatly enjoyed his time in the Spirit Realm, but that he would prefer to see the Elven City restored and so joins Arianwyn's counterattack.
One of the requirements for the completionist cape and the master quest cape requires the player to aid Lord Amlodd in cleansing shadow cores by gathering 15 of each type of core (blissful, truthful, manifest) and claiming a Divination XP lamp from Lord Amlodd. Do not use a legendary pet to pick up the cores. If you do the cores will not count toward the 15 required. Boosts can be used to receive this lamp and complete the achievement.
The title of this task is misleading, you do not have to cleanse the cores. If you keep them in the bank, that will fulfill the task and you will also be able to count the number of shadow cores collected.
