Now retrace your steps back to the courtyard, where a tough Phantom will spawn. Use the Oni Weapon dual blades against it to generate大量 Yellow Souls and charge your weapon.
Once fully charged, press G to use it. This Oni Weapon has very high attack priority and can interrupt attacks from both minions and bosses.
After defeating it, head back. When you reach the gate, you'll find the path blocked again, so take the small path on the right.
Opening the door will trigger a scare, so be prepared.
Once the door opens, there are some materials to collect on the right.
The main path is on the left. Open the gate to return to the area where we previously encountered a swarm of Phantoms.
Return to the area previously blocked by ropes; there's a save point nearby.
After saving, go to the platform ahead to absorb Black Souls and view the illusion. Afterwards, we need to open the Sasaki Ganryu we encountered earlier.
Here's a brief overview of his attack patterns.
Be cautious when you see this stance, as he will perform a triple thrust with varying speeds: fast-fast-slow.
This is his upward slash attack, which is well-suited for using Flash.
He charges up a horizontal slash while moving sideways.
When he jumps into the air, he can perform either a downward slash or a kick with his feet.
His grab attack involves raising his left hand into the air. With slight attention, it's easy to dodge and counterattack.
When facing powerful enemies, breaking their guard allows you to enter Critical Flash mode and target specific body parts for different effects.
Red marks reduce more stamina, while purple marks release more souls. Use the directional keys to select.
