Cathedral of the Sacred blood Part 1(Act 2, Chapter 1)

Teleport to Ruined City center, park ruins.

Move towards the ladder ahead. Interact with the statue to lower it.

Go up the ladder, towards the blood spring. After the scene, enter the cave.

Keep moving until you reach another ladder. Follow the path to the right, sticking to the wall, which leads to a depths map.

Head down the path to the Cathedral of the Sacred Blood.

Once inside, go down the straight path until you reach a mistle (save point); activate it.

Keep going straight until you reach an area with a Lost (enemy). Beat it.

Take the south western path and follow it to a dead end locked door (after going up some stairs). Collect the items found here.

Head back to the fork where you fought the Lost.

Take the North western path, then turn left.

Enter the room to the north west. Defeat the large enemy inside and pick up the regen upgrade (2).

Head straight out of the room and take the stairs ahead of you up to collect Queen Steel.

Go back to where you turned left before the room with the upgrade and go the other direction.

Take the south east path.

Follow the path until you reach some stairs; go up them for an item (be careful of the hole). Continue advancing. One path leads to a locked door, and another leads to a small room with an enemy, then back to the first fork.

Go back down the north west path, then turn right. Take the other path you haven't taken yet.

In this path, there is a circular room to the right containing a Vestige. IMPORTANT: DO NOT TAKE THE VESTIGE IF YOU ARE AIMING FOR THE BAD ENDING.

Before continuing past the room with the Vestige, go back down the path opposite to the room going south west of it.

Take the stairs going down to get an item, then head back up and continue south west to another staircase going up.

Follow the path, picking up any items on the way. You will arrive in a circular room with an enemy; after beating it, advance.

Turn right at the first fork, then go straight (ignoring the second fork) until you enter another room with an enemy and a lever.

Beat the enemy and open the door (this is one of the locked doors you found before).

Follow the other path out of the room (not the door opened by the lever or the way you came in).

Follow it to an open space with an enemy that possesses a corrupted mistle (an unpurifiable save point). Defeat it, and the area will be mapped out.

Go back and take the other path in the second fork until you reach an area with an enemy in an open space. Beat it.

Go down the ladder. From the ladder, jump down the ledge in front of you.

Pick up the item and head into the small circular room near you. Beat the enemies there and collect the item in the chest (1).

Follow the path down another ledge.

There is a corrupted mistle here you can purify to map out the area.

Follow the path into a tower, climb up, and open another door you found previously.

Continue down the path, picking up items. You will see a staircase going down to a chest on the way; open it (3).

Continue down the path and jump down the right ledge.

Follow the path to a resting mistle (save point).

Continue out on the path ahead (leading to two locked doors).

Jump down a ledge near the mistle onto a small area around the pillar below.

Follow it to a ladder and climb it. This leads to another ladder which will open the door to the left.

Go down the ledge back to the path leading to the doors and go through the left door.

Beat the enemy in the room, go up the stairs, beat the enemy there, and advance out of the room.

Follow the path to a room with 2 enemies; after beating them, advance and jump down the ledge.

Head into the room behind you, beat the enemy, and open the door with the lever.

Go back to where you dropped down to; there will be a ledge near the door way which led into this room. Drop down.

Enter the room and beat the large enemy. There is a Vestige (9) here.

Go through the other door to a ladder and climb it, then climb another one.

Follow the path (beating enemies on the way) until you reach a staircase.

Go up the stairs to activate a mistle (save point) and rest.

Head straight down the path ahead. There is a fork: one side has an item (for Gustav's quest line), the other leads to a staircase.

Go all the way down the stairs.

You will reach another fork; take the left path to face a very powerful sub-boss level enemy. Beat it to receive a regen upgrade.

Go down the right path and beat the enemy in the room before breaking the boxes in the corner for an item.

Go up the stairs, beat the enemy, and continue down the path until you reach an area where you can see a corrupted mistle across a gap.

Go up the stairs near you and head straight (the door to the right is locked).

Continue down the path collecting items and killing enemies.

Eventually, you will reach another fork. For now, go straight into the room in front and up the stairs.

Follow the path (not dropping down anywhere, picking up items) until you reach a room with a lever allowing you to open the previously locked room.

Return to the fork.

Head straight into the tower but do not go upstairs.
