An optional glitched route can be used early in the game to access the the top of Firelink Shrine for free. By running towards a tree situated next to the roof and performing an extremely well-timed jump, the player can make it onto the top of the shrine without having to spend 20,000 souls on the tower key, which is normally required to access the area. Doing this will also net the player an extra Estus Flask, which can found in the upper rafters of Firelink Shrine.
