Before heading to the next mission, you can interact with this stone statue now. You can exchange Red Souls for other items here.
However, exchanging with Red Souls is quite expensive, so you can ignore it for now.
We'll now follow the new objective marker. Come over and hold F to use the new ability to tear open the Miasma Wall.
We can encounter new Phantom Demons on the road. These demons have shields, which we can break using the new ability.
The default key for this ability is the mouse side button.
When you get near the objective marker, use the new ability again to tear open the Miasma Wall.
Once you arrive, let's destroy the "tree" emitting the miasma. The black fog below can only be endured by pushing through; entering it causes damage, so just move quickly.
Keep going straight; there are stairs on the right leading to the rooftop.
Once you're up, chop the tree a few times. After destroying it, you can move around freely in the area.
Then head directly to the opposite side.
After jumping down, go up the stairs on this side.
After jumping down, continue to tear open the Miasma Wall.
There's more miasma ahead, so climb the stairs to the rooftop instead.
The tree is on the opposite side; walk over there from here.
First, defeat the enemies upstairs, then take care of those downstairs, and finally absorb the Prison Window.
After absorbing the Prison Window, the path ahead is accessible. Let's proceed across the rooftops.
Then head in this direction from the rooftop.
Climb the stairs from the main street, and you'll arrive at the location of the tree.
After destroying the tree, a new boss, "Hundred Filth," will appear at the Prison Window ahead.
Let's take a look at Hundred Filth's attack patterns together.
The first is a simple fast-fast-slow three-hit combo.
When it puts the axe behind its back, it performs a small dash attack.
There's also the classic jump-down slam.
There's also a spinning slash; if you block the first hit, there won't be any follow-up attacks.
Another attack involves dragging the axe behind you and then slashing forward.
The White Filth from the Prison Window doesn't have phase changes. Defeat it and then absorb the Prison Window.
Continue forward and destroy the last objective.
