How to Get Arcane Shadow Pants in Throne & Liberty You can obtain the Arcane Shadow Pants by defeating the Grand Aelon Guild Boss in Throne & Liberty. Before you can fight Grand Aelon, you must complete the Purification Efforts Milestone, which requires your guild members to complete 100 Resistance Contracts on the Purelight Hill. This is not a guaranteed drop, you may have to defeat Adentus multiple times to get the item. You can also craft this item at the Senior Armor Crafter in Stonegard Castle, if you have a Precious Lithograph: Arcane Shadow Pants.
