Enter the doorway and talk to the man on the right. If you decide to join the Bell Keeper covenant, you’ll be awarded a Bell Keeper's Seal ring. Head up the stairs, watch out for the holes in the floor, and defeat the Dark Spirit Bell Keeper. The Dark Spirit Invaders may look small and relatively harmless, but they pack quite a punch if you get hit. They also inflict dark magic damage, so even if you have a shield that absorbs 100 per cent damage, unless it has 100 per cent dark magic resistance as well, you will still take damage.
Nab the item in the corner to obtain a Skeptic's Spice. Drop down through the hole in the center -- you'll take a bit of fall damage -- and open the coffer against the wall to find a Blue Tearstone Ring. Go to the alcove in the corner of the room to find another Skeptic's Spice, then head back up the stairs to the third floor.
Two more Dark Spirit Bell Keepers are waiting for you. Watch out for the explosive barrels in the room, and move around to separate the two enemies so you can fight them more easily. If you get too far away from either, they use firebombs, so be mindful of that as well. You can't enter the mist in the corner yet, so climb the ladder on the other side of the room.
On the next floor are three Dark Spirit Bell Keepers and their leader, dressed in red. Depending on your luck, not all of the Bell Keepers will be in the middle of the area, but there will be some around the top of the ladder, so be wary when you reach the top. You can trick them into falling to the room below, but as long as you stay in the middle area, you can avoid fighting too many at once.
Move around until they start to separate, then take them out one or two at a time. If you don't get the attention of all of the Bell Keepers at the outset of the fight, there will be one or two around the outskirts of the room. Explore the outer edge of the area to find the remaining Bell Keepers, as well as another Skeptic's Spice. Open the chest in the corner to obtain two Radiant Life Gems and Twilight Herbs, then pull the lever on the side of the area to ring the bell and remove the gate blocking the mist on the floor below.
Boss Battle: How to Beat the Belfry Gargoyles
The longer you fight the Gargoyles, the more difficult the battle becomes. It begins with only two Gargoyles attacking. However, as the fight progresses, a total of six Gargoyles join the fray. While the Gargoyles all share a single health bar, if you do not kill any them individually, you will end up fighting all six at once by the end.
There are four main attacks that the Gargoyles use. They breathe fire on the ground or in the air. In the air the fire breath is always a frontal circular attack, while the ground-based flame can be a linear attack or a circular attack. Avoid these attacks by staying a moderate distance away from the Gargoyles when they prepare to breathe fire -- watch for the key tell that they're about to use it: their head will pivot.
When the Gargoyles jump in the air, in addition to the fire breath, they may dive toward you. This attack doesn't have a great deal of range, but it has a lot of recovery, meaning you can attack the Gargoyle as soon as it lands. If the Gargoyle jumps over you or to the side of you, face that Gargoyle immediately to block the attack that follows, or dodge to either side.
At close range, the Gargoyles use two different attacks. They use a frontal circular melee attack that can be followed by an overhead linear melee attack. Neither attack has much range, and the linear attack is easily dodged to the left or right. They also pause for a moment to channel lightning, then use a lightning attack that covers a moderately wide radius around themselves.
While you will inevitably be fighting multiple Gargoyles at once, they do not attack as often as other enemies, especially compared to the battle against multiple Sentinels earlier in the game. Use a weapon that inflicts as much damage as possible, even if it attacks slower than some other weapons. Weapons that can hit multiple targets with ease -- those that have a wide, cleaving swing -- are especially effective. However, if you have ranged attacks such as magic, arrows or crossbow bolts, they are extremely helpful in this battle. With ranged attacks, you can stay at a distance and inflict damage for most of the encounter.
After the bosses are down, search the far side of the rooftop to find a Soul of a Proud Knight near the far corner, to the left of the doorway. Head through the doorway and down the stairs. Open the coffer at the bottom to find a Southern Ritual Band, then continue through the next doorway and light the bonfire at the end of the path.
Head down the ladder to the right to engage seven dogs and Vorgel the Sinner. Take out the dogs as quickly as possible so you can focus on Vorgel by himself. Vorgel attacks multiple times in rapid succession, will parry your attacks, and will use a guard crush attack to knock your shield away temporarily. Wait until you see a pause in his attack pattern, then get in as much damage as you can before he begins attacking again. Have a few health items ready, especially if you're going in without a proper shield.
Defeat the enemies, then pick up the Bastille Key at the end of the hall. Climb the stairs to find an Enchanted Falchion on the balcony above. With the Bastille Key, you can open the doors at the end of the two staircases just before the entrance to the Lost Sinner boss battle. The door on the right provides a Smooth & Silky Stone, while both doors allow you to light fires in the boss battle room to make the fight a little easier.
You can also go to the top of the Lost Bastille and open the cell in the room with all of the zombie-like enemies that explode on the floor. Inside the cell is a Petrified Dragon Bone and three Firebombs.
