Sometimes we're in parties with the one person who isn't great at jumping, which can make some encounters extremely frustrating for them and the group.
What if we had a new autogranted feat that let a party member teleport line of sight to another party member?
Presenting Use Rope!
Target, use the feat, and there you are!
I think we can for ease-of-use and realism reasons do away with the DC checks, as the only use in this case will be when there's someone else helping to situate the grappling hook - a ledge that catches back, if you will. I also don't know what kind of range it should have but I don't see why not just c/p the standard (non-ray) spell casting range.
