I am stuck trying to cut the vines in the Skull cave. I do see the cane there, however I have no idea how to select it or pick it up. Can you help?
The cane has no relation to the vines. If you can't pick up the cane, you can't interact with the vines. Log completely out and log back in, it should resolve itself. Sometimes my character is unable to enter a sigil because the game won't recognize the interface. I believe this is the same issue.
They are not the same quest line. Move to the cane and you should get a dialog box...just travel around to the cane. Then you get to the plants, a different dialog box pops up, and do an 'x' to cut the vines.
