Inside The Lair of the Deposed King, we can find only two Darksiders II collectibles, both of them revealed by the following game guide.
One of them is a Power Stonebite we can trade with Blackroot, and the other one is a Lost Relic we can give to Ostegoth.
The Darksiders II Lair of the Deposed King area features five levels, but the collectibles can be found only on two of them, as presented by the maps below.
For each collectable in The Lair of the Deposed King, a specific symbol was added to the games map, with the purpose of helping us to identify these important items.
The Power Stonebite in The Lair of the Deposed King is marked by a red diamond and the Relic of Etu-Goth by a blue cross.
Relic of Etu-Goth Location
When we enter the Lair of the Deposed King through the door in Basement 2, we go down the stairs and to the right there is a broken staircase.
We need to drop down and then turn around to see the Darksiders 2 Relic of Etu-Goth right under the stairs.
Power Stonebite Location
At the end of the spiral staircase (Basement 4) is an ornate door with four crystals (the door that needs to be opened using the key from Vulgrim, after we give him another chapter in the Book of the Dead).
Above that door is a statue similar to a dragon head, and on its forehead is a Stone of Power that can be collected using Strife’s pistol.
