Ah, chains. They are both fun and a pain. To make it look good, you pretty much have to have a bone for every single link of the chain, placed at the "top" (if it were hanging down) part of each rung. For an example of bone placement, you can look at my Blade model. It doesn't have a fully rigged chain, but you can see where the ideal bone placement is for the hanging chains on the side.

I can place bones/joints but my problem is making the bones/joints interacting with the model and the tutorials i've looked at aren't making any sense to me!
if you could just link me to a good tutorial that'd be nice!

Edit: I found the bind command but now my problem is that the very end of the chain of the keyblade is part of the polygon object that i do not want to mess with!
