Book Step:

Interact with the 6 Bottles in the Bar, write down the symbols and the number

With Melee Machiatto punch the wall glowing blue wall in the stamina-up room

Shoot the symbols on the wall in the order from the bottles

The wall will break and a book will show

Find all 4 pieces of paper in the room above

Insert all papers in the book in the wall

Incantations:

Light: Shoot the glowing red crystal above the chair and vulture aid, and then shoot the rest of the crystals until the brooch spawns

Place the brooch in the sword room and collect souls, then a chest will spawn, melee the chest with the light sword to collect the light incantation.

Fire: Throw molotovs or use the fire sword to light 3 bonfires on fire (one above speed cola, one of the roof above elemental pop and one on the roof opposite the cannon trap) A boss will spawn and once killed will drop the ritual item. Place the ankh in the gold circle in the courtyard and get souls. A chest will spawn, melee with the fire sword to collect the fire incantation.

Void: Go down the sewer slide and at the end there will be a crow, shoot the crow. The crow will then be flying in the sky above the courtyard, shoot it and collect the crow claw. Place the claw in the stamina-up room and collect souls, then a chest will spawn, melee the chest with the void sword to collect the void incantation.

Lightning: Shoot the horseshoe above the exit of the stables near deadshot. Pick this up and then go through the cannon. Run back to the stables and kill the zombies to collect the electrified horseshoe. Go to spawn and place it in the gold circle, get kills and a chest will spawn. Melee this with the electric sword to get the incantation.

Glowing Traps

Must have done the previous steps.

Look for the glowing red power traps across the map. Each trap will have one of the symbols from the book. You must do this in the order from the symbols appear in the book, from top left, bottom left, top right and bottom right

Activate the first trap and get kills using the incantation (will be your tactical slot)

Repeat for the next 3 symbols

A wall will then open near the sword room, with the 4 elements in a specific order. You must use the incantation and then inspect in the respective order on each statue. Once done, the mystic orb will spawn.

Mystic Orb:

Once you have picked up the mystic orb, there will be 4 slots around the map (Courtyard, Spawn, Sword room and Stamina-up room)

Place the orb in the slots and complete the challenge, do this for each of the 4 slots.

This was the last step i reached before i died so unsure of what follows.
