I can’t seem to find anything on the topic of grappling hooks. What is the difficulty to throw them? Or what are the different situations where they can be used, along with the associated difficulty? Supposing one is climbing down by means of one, and one wanted to free it (detach it) afterward, how would one do that?
I’ve checked the PHB & DMG, and they are completely mum, as far as I can see. Are there official rules somewhere? Or do folks have homebrew rules on this?
