Dungeon room generator
From D&D Wiki
You will need: a deck of playing cards, a coin, a d%, a d10, and something to work as a d3 To use this system you draw a card from the deck and put it aside, draw two more cards and put them aside, if you drew more than one "trap card" you discard all but one "trap card" if you end up with more than one face card of the same type (for instance two kings) discard to one of those face card types, at this point you must keep drawing (following the same rules from above) until you have three number cards under 8 those are you room's dimensions, other than that it's pretty self explanitory Rooms: Face = Monster in room
Ace = Monster with treasure King = Monster with minions Queen = Mutated monster Jack = Monster with magical weapons/abilities
Numbers from 8-10 = room with trap
Numbers from 2-7 = Length/width/height of room
7 = roll a percent die 6 = 35 ft 5 = 30 ft 4 = 25 ft 3 = 20 ft 2 = 15 ft
Monsters: roll a d3 1 = MM 2 = MM2 3 = MM3 Then roll 2d100 and use the monster on that page, if that page contains no monsters/does not exist, re-roll.
Traps: Roll a d2 1 = magical trap 2 = mechanical trap If mechanical roll a d20
1: poison needle 2: fake door monster 3: acid spray 4: pit 5: swinging axes 6: arrows 7: cave in 8: flood 9: some parts of the floor are fake 10: crushing walls 11: airless room with closing portcullis 12: room fills up with grass 13: room fills up with gas 14: room fills up with sand 15: BOMB!!! 16: poisoned irresistible food (DC WILL 15) 17: levers that do... DM'S choice :) 18: exploding walls 19: lever that turns the floor upside down (dropping players into... IDK) 20: Re-roll twice*
If magical roll a d20
1: fireball 2: lightning 3: anti gravity room with spikes on ceiling 4: door disappears behind you 5: door on far side of room leads out of the door behind you 6: room fills with flying paper strips enchanted by the "keen" ability 7: testing room for dangerous/ unstable magic 8: stacks of carnivorous skulls 9: room is the stomach of a large creature 10: flash freeze 11: flood then flash freeze 12: room acts as though affected by a blizzard 13: tornado 14: Time is sort of, oh I have a headache 15: this room is the still beating heart of the tarrasque 16: DM's choice 17: in the middle of this room is a sheep... It may be normal, savage, or explosive 18: the kitchen of a monster hotel... Staffed. 19: this room has a complex puzzle in the middle, The door you came through isn't there, and none of the players can talk until they get out ( if you want to be really mean you can make a timer (crushing walls, flooding room, spreading magical flame O.O)) 20: re-roll twice*
- if you roll this again restart the trap process.
