Sure, why not. Also lets have blind characters automatically fall without asking them whether they want to enter the Rift.

It makes sense since a blind character wouldn't see how dangerous the descent is, but it should come with several penalties on top of already existing ones since you're, well, trying to climb down without any vision.

Now that I think of it, maybe this could be implemented in a more emergent way: have blind status-effect temporarily modify the perception stat to 1 for its duration.

Perception is not only about vision, it's also hearing, feeling, smelling etc.

Agreed.
