Place the Carian Inverted Statue on the pedestal and the entire dungeon will be flipped on its head. Yes, this place works upside down, too. Yes, Preceptor Miriam is back. Elden Ring!
As soon as you get to the elevator that used to take you up into the tower, it’s clear something is amiss. Jump down into it, walk through the gap, and kill the sentient hands. Hop over to the next platform and kill Miriam again to get the Lucidity Sorcery spell.
Once you’re done, make your way to the area with the chandeliers. Hop onto them and carefully drop down onto the beams until you can reach the elevator you could previously see suspended from the ceiling in the non-inverted version of the tower. You’ll emerge at the Divine Tower of Liurnia.
Here you’ll fight the Godskin Noble, but this time he’s much easier because you have much more space and the ability to use your horse. Simply keep charging at him and attacking before galloping away. Rinse and repeat. You’ll get the full Godskin Noble armor set for your troubles, though it’s not exactly fashionable.
Now head to the Divine Tower of Liurnia, go right to the top, and you’ll find the Stargazer’s Heirloom (a really good accessory for mages, increasing the intelligence stat) and Cursemark of Death.
