Peasant Railgun

I personally adore the Peasant Railgun and other such silly tropes generated by player creativity! Lateral problem solving can be one of the most fun parts of the DnD experience. However, these shenanigans often rely on overly convoluted or twisted ways of interpreting the rules that often don't pass muster of RAW (Rules As Written) and certainly not RAI (Rules As Intended) -- despite vociferous arguments by motivated players. Any DM who carefully scrutinizes these claims can usually find the seams where the joke unravels. The DnD authors also support DMs here when they say that DnD rules should not be interpreted as purely from a simulationist standpoint (whether physics, economy, or other) but exist to help the DM orchestrate and arbitrate combat and interactions.

In the case of the Peasant Railgun, here are a few threads that I would pull on: * The rules do not say that passed items retain their velocity when passed from creature to creature. The object would have the same velocity on the final "pass" as it did on the first one. * Throwing or firing a projectile does not count as it "falling". If an archer fires an arrow 100ft, the arrow does not gain 100ft of "falling damage".

Of course, if a DM does want to encourage and enable zany shenanigans then all the power to them!

TFA is actually the first time I've seen the peasant railgun interpretation that actually causes damage. Other conversations I've seen all concluded it wouldn't do any damage, which made it even funnier depending on your point of view.

Two of my favorite bits of D&D (3.5) logic:

* Mounting a horse is a free action. Therefore, much like the peasant railgun, you could set up saddle highways: a post every five feet, with a saddle on top. Then, you mount and dismount between cities as one gigantic free action, allowing instantaneous travel.

* Per the rules governing object visibility at distance, the moon was invisible.

* Arguably, once you started drowning, you could not stop drowning, even if removed from water.
