From Skullcrushers to the Super Shotgun, what firearms are the best in the Slayers arsenal?
There are a total of 11 secrets to find in the Reckoning level of the game. Some are more well hidden than others, and we know where to find all of them.
Codex (Marok)
At the start of the level, take a right after dropping from the ledge to find a Codex in the side of the building.
Life Sigil #1
After defeating the first area of enemies, head up into the cave behind you to find the Life Sigil and a path back up to the Codex location.
The Old One Toy
After clearing the room above of all enemies, a door containing The Old One Toy will open up.
Gold Chest #1
Head to the location above and enter the room. Look down and jump on the jump pad at the bottom, then shift forward to land on the bridge above you. Smash through the wall at the end of the path to find the secret area with a gold chest.
Ruby #1
Go along the pathway from the top of the jump pad in the last step, then drop down to find the next Ruby.
Gold Chest #2
Drop down from the narrow path to the enemy encounter (see map above), then break through the wall to find the gold chest.
Gold Chest #3 + Life Sigil #2 + Ruby #2
Upon entering the large building (see map location above), head down the side hallway instead of up the normal path and find the breakable wall. Smash through it to find the path inside, which leads to a climbing wall and a gold chest.
From here, find the next climbing wall to the side of the chest and leap to it, then use the Shield Switch at the end of path to open a way to the Life Sigil. Turn around from here and continue climbing up the path to reach the Ruby and the second secret area.
Secret Key
The secret key can be found inside of the large room you drop into at the end of this area of the level. Grab it and head out the door behind it.
Life Sigil #3 + Ahzrak Toy
Drop down from the secret key and immediately look to the locked door to your right. The Life Sigil and Ahzrak Toy can be found in the secret area behind the door.
Ruby #3
Head back to the location above and unlock the door with the secret key to find the Ruby inside.
Gold Chest #4
Return to the castle full of hallways to unlock this door with a gold chest inside.
Wraithstone
In the same castle, head to the locked near the main enemy encounter area to unloock them and grab the Wraithstone.
Blue Orb
Unlock the door near The Old One Toy using the secret key to find the blue orb and some gold bars. Good job!
