Make sure to grab the Black Knight Glaive from the boss arena and then head toward Firelink Shrine, where you’ll encounter a number of Black Knights, but each is far enough from the others that you won’t have to fight more than one at a time.
Check the area to the right of the shrine entrance for the Hornet Ring and then pass the entrance and head toward the locked gate on the left side of the shrine for the Chaos Blade . Backtrack and head up the stairs for a Soul of a Crestfallen Knight and then enter the darkened Firelink Shrine.
Collect the Coiled Sword Fragment from the bonfire location and then speak with the Shrine Handmaiden, who has her own inventory that you can only access here.
Make sure to grab the Blacksmith Hammer , where Andre the Blacksmith is usually located, and then head down toward the right side of the area to where Irina is located to reveal a hidden path with the Eyes of a Fire Keeper .
Note: The Eyes of a Fire Keeper must be given to the Firekeeper in order to achieve the ending, "The End of Fire".
