Dead Warrior Catacombs in Elden Ring

The Catacombs of the Dead Warriors is where you fight Radan, Starbane. It's in the southeastern part of the Starry Wastes. Once you defeat Radan, do not rush to leave the location. Or, if it was abandoned, return to the place of grace and move north. on the left side of the coast, in the rock there is an entrance to the catacombs. Activate the place of grace of the same name.

There will be dangerous ghosts inside the catacombs. Run forward. You can bypass the ghosts. You need to climb the second steps on the right. Having done this, enter the passage and run past the archer. No need to jump out the first window. After 2-3 turns to the right, look for a window on the right. Jump through it and go up the stairs to the left. There will be a room with rot ahead, but you turn into the passage on the right and look on the left for an archer and a statue with a lever.

The heavy door itself is located not far from the room with the first ghosts. Here, going for the lever, we turned onto the steps on the right. But now you need to run straight ahead, without turning anywhere, and go down to the opened door. You will have to fight with the Putrid Tree Spirit. For the victory, we will receive the ashes of Oga, the knight of the Red Mane, as well as a golden seed.
