First of all: after defeating the boss in the sewers, I went to the tower to unlock the third ring slot using the boss’s blood.
The vial has been drunk and the slot is still blocked.
Secondly: I don’t know if you know, but GeForce Now has a CTRL+1 shortcut that is used to take screenshots. And you decided to assign this shortcut to changing runes, for example on a bow. This way, you cannot change the runes on the bow because GeForce Now blocks this shortcut.
Due to the fact that in 2024 the keyboard cannot be changed in the game, the bow is unplayable. Before the last patch it still worked with the mouse wheel, but now it doesn’t. Bravo
