Find Dyrnwyn’s fragments and defeat Lord Reto
Quick answer
Read a Mysterious Location Vegvisir in a Putrid Hole. Follow the markers to the tip altar, the blade altar and finally Lord Reto’s tomb. Store the earlier fragments before the fight. Reto’s sword attacks include delayed feints: move completely out of reach, wait for the strike to finish, and take short openings instead of relying on a routine parry or early roll.
