After descending to the 5th level (the beginning of the catacombs) and wandering around a bit, you’ll find a group of rooms that form either a diamond or a cross—it’s hard to tell. In the southwest are two doors that lead into these rooms.
At the entrance you can read the Book of Blood, which says something like this:
“Locked by the gates of blood, separated by corridors of fire, valor awaits the hero who will awaken it.”
This is the beginning of the legend of the ancient hero Arkane, who had once visited this labyrinth, battling hordes of monsters. Rumor has it that Arkane, rightly believing that evil might return, decided to aid the hero who would follow his path and hid his legendary armor, Valor, in the labyrinth.
Go into the next room, take the Bloodstone, and place it on the Pedestal of Blood. The pedestal will partially fill with blood, and you’ll see one of the doors on the north side open.
Go there, kill the guardian monsters, and take the next blood stone. Repeat the process and take the final, third stone from the room on the southeast side. After this, the blood gate will open a “corridor of fire”—a tunnel lined with torches. All that’s left to do now is kill the remaining monsters and take the armor.
