The Peasant Railgun Problem

• In D&D, a turn represents six seconds
 • Every creature gets one action, one bonus action, and one reaction
 • The Ready action lets you prepare an action that triggers when a condition is met
 • 1,000 peasants in a line, each readies an action to pass an object to the next peasant
 • A spear travels through 1,000 hands in six seconds = roughly one mile = 600 mph
 • Nearly the speed of sound, and according to rules as written, this is legal

The Physics vs Rules Conflict

• By D&D rules: normal ranged attack, 1d6 damage
 • By physics: an object moving at 600 mph should obliterate anything it hits
 • The rules say one thing, physics says another

Other D&D Exploits

The Bag of Holding Bomb: Put one Bag of Holding inside another — both bags rupture, everything within 10 feet is sucked into the Astral Plane (instant battlefield control)
The Infinite Familiar Loop: Familiars can deliver touch spells; certain spells let you swap places with a creature — chain this correctly and you teleport infinite distances
The Clay Golem of Wishing: Craft a Clay Golem, give it a Ring of Three Wishes, command it to cast Wish repeatedly — the golem suffers the stress damage, not you (infinite wishes)

Why These Exploits Exist

• D&D rules prioritize game flow over simulation
 • The system assumes players won't weaponize every loophole
 • Most groups handle this with common sense — the DM says no, problem solved

What the Peasant Railgun Teaches Us

• Rules as written can create unintended consequences
 • The solution isn't to ban creativity
 • It's to understand that D&D rules are guidelines, not physics engines
 • When rules and narrative conflict, narrative wins
