Radahn
Description
Starscourge Radahn is a Legend Boss in Elden Ring. Starscourge Radahn is heralded as one of the mightiest living demigods, having fought Malenia the Severed to a standstill during the war of the Shattering. However, his resulting affliction with the Scarlet Rot caused him to be driven to insanity, crippling him and reducing him to a state of feral rage. He is located in Caelid, where he can be accessed from Redmane Castle after activating the Radahn Festival by progressing far enough in Ranni's questline, or activating any site of grace in Altus Plateau. Radahn is an optional boss, and doesn't need to be defeated to advance Elden Ring's main storyline. However, he is a shardbearer, and two of the five available shardbearers must be defeated before entering Leyndell, Royal Capital. In addition, he must be defeated to access Nokron, Eternal City, achieve a certain ending, and unlock the Shadow of the Erdtree expansion.
