Peasant Railgun

A note to my fellow DMs: if your players badger you into allowing this, remember that their enemies - typically BBEGs like Kings, Dukes, Wizards, Liches & the like - are much more likely to have two thousand peasants at their disposal than the party is.

BBEG: "I have to give this one to you heroes, I thought peasants were a lot less useful than you did apparently, time to make use of those conquered villages I guess"

"Looks like I'm going to have to conquer a lot more villages. Say, come to think of it, is there any reason the peasants have to be alive to fire the railgun? I don't have to feed zombies..."

And if the players seek out the right artefacts of power (or bribe a level 17 wizard), they may be able to Wish away the loophole, bringing their nigh-indestructible enemy back down to mortal (unmortal?) levels.

I was just chatting with a player about how shitty the Wish spell, as written, is.
