The Dark Chapel

Start by defeating the two Mini Devils that fire crescent projectiles. Save your game to the right, then proceed upwards through ledges, defeating one more Mini Devil before exiting at the top right.

In the next room, deal with Ghouls (upgraded Zombies) and a Witch. Ghoul souls are useful for consuming normally unpalatable items like Rotten Meat.

Continue to a room with Ghost Dancers (destroying one takes out both) and an Amalaric Sniper. Grab the Potion by hopping up ledges and jumping right. Drop to midway, enter the room on the left (a warp room), then head to the bottom of the room, fighting enemies including The Creature. Enter the bottom left door.

Head left to find a Hell Boar (a blue Slaughterer that also uses fireballs and an uppercut). Ghouls are also present. Proceed through the room.

Enter a shaft. Take the top left door to find a Barbariccia. Grab the $2000 and return to the shaft.

Drop through the shaft, avoiding Bone Pillars. Take the first left to find a White Dragon. Get underneath it to dodge attacks and defeat it. Collect the Traveler Cape and return to the shaft.

Continue descending the shaft. Head left. Defeat a Guillotiner (which splits into two parts, but only one needs to be destroyed). Descend the shaft to the bottom and take the right door.

In this room, you'll find another Barbariccia. Before engaging, note the spike traps on the ceiling. Lure them down and run under them. There are two sets. In the next room, grab the Red Scarf.

Return to the shaft and take the bottom left door. In this room, destroy Bone Pillars (the Mandragora soul is effective here) and the Hell Boar behind a partition. Equip the Skeleton soul, use a bone to break the pink wall with a Skeleton picture. A White Dragon will appear; dodge its fireballs and get underneath it to defeat it. Collect the Halberd.

Backtrack to the Ghost Dancer room (check the map if needed; it's adjacent to a warp room). Head to the top left corner and go through the door.

In this room, defeat the two Great Armors. Use Bullet Souls and your weapon, backing up when they get close. The Great Armor soul is a familiar. Continue through the room.

The next room contains a Valkyrie. Defeat her. Exit through the upper exit.

You'll face a Witch and Ghosts. Ride the platform up, jump to the right platforms, and exit to the right.

Ascend the shaft to the top and head right into a passage with a Tombstone. Defeat it (its soul stops petrification). Head to the next room, the bell tower.

Defeat the Mini Devils in the bell tower while climbing to the top left corner. Collect the Anti-Venom. Backtrack to the last shaft. Use the top left room as a save point. Drop to the bottom of the shaft and enter the door to face the boss.
