The secret and five gold are inside the door on the left, which you may open just before the wall where the stone imps smash through.

8 Gold (114/210)

You will reach an outdoor area where you must descend, pass the fire-sprinkling pipes, ascend a short set of stairs, climb the wall on the left, and gather the five gold coins. Look to your right now to spot a wall that you can smash with your shield. Leap in and use the valve to extinguish the fire at the pipes. The secret, nine gold, and a life sigil are hidden behind a wall that a hell knight will breach if you enter the recently opened portal.
Secret Area 7 & 8 Gold (152/210)


Once you have defeated every enemy in the next required battle, a door on the left will open, revealing eight gold.
Secret Area 8 & 50 Gold (202/210)



Just to the right of the second Sentinel Shrine is a hole in the wall; proceed all the way to the end of the walkway to uncover the secret and a box that holds fifty gold coins.
Secret Area 9 & 8 Gold (210/210) + Shredder – Nightmare (Weapon Skin 1)




To locate the weapon skin, climb past the Sentinel Shrine, look left to see three boxes, climb up, and then climb into the vent to discover three gold. Then, descend down the next hole to find five more gold.
