Siegward — old cell
NPC · Dark Souls III

Later in his quest, Siegward is locked in an Irithyll Dungeon cell. Its usable entrance is reached by a detour through Profaned Capital: climb onto the toxic chapel roof and jump across to the window by the Court Sorcerer. The Old Cell Key is needed to unlock the cell; seeing him from the giant chamber is not the same as reaching the door. Free him before first entering Yhorm’s arena for his quest assistance there. Position and height are approximate.
