How to Get Aged One's Exultation Talisman in Less Than a Minute (Elden Ring DLC) 

Short and sweet exactly where to find as well as how to kill the enemy that drops the Aged One's Exultation in the Shadows of Erdtree DLC. To damage this enemy all you have to do is parry its grab (if you fail there is a Stake of Marika right there so no worries). In the video I used Golden Parry which can be found in the base game. I did this all naked to show just how quick and easy this can be done. Good luck hopefully this helps!
