This one is well hidden, and also requires an investment of Souls to gain access to the area. Read on for how to find the Estus Shards - if you're looking for the Bone Shards, hop over to our Dark Souls 3 Bone Shards location guide. Some are tucked in out of the way locations and others in areas that require dispatching an enemy horde, but the detours and extra fights are worth your time - having that one last shot of healing power could make the difference between success and failure. Upgrading your Estus Flask and bonfire through the use of Shards is important for survival in the Kingdom of Lothric, and to help you on your way there are eleven Estus Shards and ten Bone Shards to be found as you progress.
