Short rests take about an hour, long rests about 8. Thats fine, makes for a fun light-hearted adventure. But do you long for a grittier game. Do you want to suffer and fear for your life at every bump in the night? Then do i have good news for you! Introducing a rule hidden away in the DMG that makes short rests 8 hours, and long rests take a week. Not only that but I, your GM, will be throwing difficult and dangerous encounters and puzzles at you with nary a second to catch your breath. If this is the game you have been longing for then look no further. Sign up here!
Cheesy stuff aside, i came across this rule while reading through my DMG and it sounds pretty rad so i wanna give it a shot. Im not very good at worldbuilding unfortunately as a DM so i might not be the best person for this job and ill gladly step aside if someone wants to take over as the GM but i thought id bring some attention to this at least.
