Q 167

Is there any kind of noise or stealth related check for throwing a grappling hook onto the top of a building to climb up? If so, is there a way to muffle this?

Example - Clandestinely trying to enter the second floor of an occupied building, so I want to use my grappling hook to ascend. I assume I need to move silently to climb without being heard, but what about the hook itself?

We didn't know the rules so I made a lasso and snagged some overhanging rafters to climb up the last time, but in case this happens in the future, I'd like to know.
