Dark Souls Remastered | Reigniting Firelink Shrine bonfire after defeating Lautrec

It is optional to free Knight Lautrec early in the game. If you choose to do so, he will later kill the firekepper at Firelink Shrine, causing an inconvenience. It is optional to use the Black Eye Orb to invade his world and kill him in order to reclaim the Fire Keeper Soul. Once the Fire Keeper Soul is reclaimed, you can choose to keep it for yourself or to reignite the Firelink Shrine bonfire. If your Estus Flask isn't fully reinforced, I I suggest using it for that purpose instead.
