If you can sprint under the Dragon's perch, you'll find a room under the tower with a Mimic posing as a chest. There are a few items up on the wall, and you'll need to be fast to sprint along to find a Claymore among them before jumping off the side to avoid getting toasted. Continue along the High Wall of Lothric until a large dragon appears to spread fire over an upper walkway. These weapons can be tricky to obtain, but are well worth the effort. When arriving at the High Wall of Lothric, you can head right along the wall to another small tower where you can find a Longbow and some arrows - just be careful of ambushes! Unless your class started with a bow, it can be helpful to have a ranged option to fights that may be dangerous up close. If you look at the far back wall where a narrow beam ends at a wall, you can strike it to reveal an illusory wall with a path leading behind the thrones to a chest holding a Covetous Silver Serpent Ring, which can greatly increase the amount of souls you'll obtain at this stage in the game. From here, you can go around to the rooftops at the front of the shrine to find an entrance to the rafters above - where a corpse holds an Estus Shard, and an odd Crow will trade certain items with you. It may take some tries, but it is possible. If you try sprinting up, you can perform a running jump and curve to the right to leap over the gap onto the rooftops. However if you aren't content to wait, you can always try using a trick to get up to the lower roof: From the belltower door, look down to see a large tree stump to the left of a lower roof.

The Handmaid sells the key for a whopping 20,000 souls which is a lot to ask for early in the game, but you should try to get it sometime around the Undead Settlement. As you explore Firelink Shrine, you may note the side passage out of the top floor to a locked belltower door.
