Weapons for NPCs

I admit that, while making this list, I tried to avoid things that would alter the way the game itself plays. However, I find this particular issue to be a constant annoyance. Whenever there is some sort of attack on my NPC houses, all they can do is casually saunter off in a direction that will, hopefully, get them out of trouble. Usually, this ends in them finding their way into a pit that is located a little way to the right of the housing area that is quite difficult for them to get out of, forcing me to reload my game if I want them to be able to make it back to where they belong. Now, I’m not saying that they need to be able to wield Excalibur or anything, perhaps just a short sword, or better yet, NPC specific weapons. The Guide can use a bow and arrows, Arms Dealer uses guns, the Dryad uses the Thorn Chakram (maybe it doesn’t need to be this specific, but you get my point). In any case, it makes it so that Blood Moons aren’t quite as annoying when all of your NPCs die and you can’t get anyone to come back because “This housing is suitable”.
