Is there a mod which ables you to unload an loaded arrow in your bow?

There is this one.

Denock Arrows is also built into Cobl if you have that. Can enable it via the ingame options menu in your inventory if so.

Thanks, the denock is just what I need. Don't have Cobl installed.

Doh forgot that one, and i even mentioned CoBL no more then a week ago to some one else incase they where using it. :banghead:

Denock arrow is made by scruggsywiggsy the Ferret for his Thieves' Arsenal (he abbandoned it to work on his OBSE).
Later he released it as a standalone mod and gave permission the feature to be integrated in COBL.
As for not using COBL - youdeny yourself a mod wich adds few hundred ingredients and few hundred books into the game. And much more. A matter of taste, I imagine.
For me COBL is an absolute must.
