This Town Ain't Big Enough

A gunshot rings out.  Choose one creature within 60ft to make a Charisma saving throw. On a failed save, target takes 12D12 force damage, and is flung in an arch directly out of a settlement - exactly backward from their position - before falling to the ground.  When the creature strikes something, each take 3d8 bludgeoning damage.  On a success, time warps to the next sunset - no matter what time of day it is - and the last to draw their weapon in a duel is flung from the settlement instead
