Secret area 1
After getting the Skullcrasher Pulverizer inside the Sentinel Barracks, move towards the next room, following the yellow marker. There, you will encounter a swarm of demons to deal with.

After reaching the open area, you will see a staircase leading to the upper section outside the Barrack, as shown in the image above.

After finding the first secret, navigate to the area shown in the image. From there, jump over the ledge. This will help you bypass a locked gate.

Secret area 4

Make your way to the Sentinel Shrine and reach the upper region of the Sentinel Barracks while killing all the demons along your way. You will eventually arrive at an open area leading to a broken bridge outside the Barracks. From the edge of this bridge, as shown in the image above, jump down to reach the lower ground. You can easily locate the area, as it has spawned some gold coins you can collect.

Once you reach the lower region, you will see a similar claw-marked wall that you will need to climb to enter the cave. There, you will see two additional claw mark walls to climb and reach the upper section. Once at the top, you will be notified that you have found one of the secrets.
Secret area 5
To exit the cave, you will find some stairs leading to a locked gate. Use your Shield Saw to break the gate, which will lead you back to the broken bridge area. Now, reach the area of the Barrack as shown in the image below and jump from the marked point to reach the ground. There, you will encounter another wall with a claw mark, allowing you to climb up.

Inside, you will face quite a few demons. After eliminating them all, look for two more claw-marked walls to reach the upper area. As you reach the top, you will discover the secret area. There, you will also find a Ruby stone to upgrade your weapon by interacting with the Sentinel Shrine.
Secret area 6
From the previous secret area, locate the claw-marked wall to climb to the top. After you reach the top, jump across to reach the broken bridge. Make your way toward the end of that bridge, and from there, jump to reach another part of the bridge. In this new area, you will encounter shielded demons. Clear them out and head towards the castle area as depicted in the image below.

You will come across a broken ridge beside the castle; jump from there to reach another section. Again, you will face quite a few demons here. Eliminate all of them with the help of your weapon, and then continue straight ahead, following a skull-shaped structure.

As you approach the bridge, jump down to reach the ground level. There, you will find stairs along with some spawned gold coins. Take the stairs and move to the upper level, where you will find the last secret.
