Their presence in NV makes it highly likely that they will be back
On the same topic would you like the ability to throw your main weapon, perhaps as a desperate attack when you are on the brink of death throwing your sword, or mace at the Dragon or Spider. It could do massive damage but would be unwieldy and inaccurate, plus you would lose your weapon. There could also be enchanted weapons that come back when you throw them.
Thoughts?
