The stairs in the north of site of grace will lead to Elden Ring Runes the location of the activation point for the Radahn's Great Rune. For the Godslayer's Greatsword you must turn south, then walk down the stairs. Keep an eye out for two Redmane soldiers near the bottom, and one is hidden in the corner.
What follows is the result of a FromSoft feature that's as iconic as Miyazaki's passion for poisonous swamps, the classic "drop from ledge to ledge making your way to at the bottom of an amazing pit" set piece. (See also The Great Hollow, Majula, and the Hunter's Workshop). The path is fairly straightforward and your first target is the cage elevator, with the Redmane soldier guarding it that is located down and towards the left the starting point. The strut that is cracked in your path could break beneath your weight, however, it's scripted so you'll take no damage from the fall , and this is your path to follow.
The elevator will take you up, and then walk the hallway towards the top of the hill. You can take a detour on the ladder and open the gate at the top. It's an escape route back to the last place of grace. There's a monk in blackflame on the other side of the hall, sporting an impressive stance and incantations that can be deadly However, he should not pose too much of a threat.
At the end of the hall, jump over the ledge your left and continue following the contour of the tower until you're in the middle of another cracked strut. As with the previous one, it may break and you're scripted to survive--there is no other route to reach the bottom of the tower--but I did experience this glitch out and the fall nearly killed me twice before causing no damage the third. If this happens to you try returning using this shortcut and then attempt to make the jump until you're safely next to elden ring weapons for sale the elevator. Continue to descend to a different location of grace, and past another blackflame monk there is a boss door leading to Godskin's Apostle.
