Card Deck Dungeon!

This is a hack that evolved organically from a hobby project to convert the Dungeons and Dragons Curse of Strahd board game into a prototype for a random dungeon deck using a standard deck of playing cards. I used 5e but it could easily be system agnostic.

The idea is simple, each card represents an encounter or encounter modifier of some sort.  You can play theater of the mind or setup each encounter on a mat or with tiles, however you might typically do things. However, the cards allow a interesting middle ground, you can actually lay them out in the shape of the dungeon regardless of how you execute combat, as sort of a strategic layer map. Almost like you’d see in a video game. This removes the need to sketch out the entire dungeon and you can just use your mat, tiles or board to map a single room at a time.

I use the suits as a thematic reference, face cards to generate more significant events. Black suits are bad, red are good. The Ace or King of Spades will typically be a boss and mini-boss encounter. Hearts control the short and long rest opportunities. You can shuffle those into the lower portion of the deck from the start or discard rest cards to shuffle any encounter back in. Face cards for other encounters might be treasure hoards or good NPC encounters. You can use the jokers as party level ups for milestone leveling or just remove them and count XP.

To generate the dungeon spatially with the cards you simply connect the cards long edge to short edge as you draw them. Each card-room has d4 doors, 1 meaning the door you came through. 2 meaning 1 additional door attached to any side you choose however it must not connect back to another room if you can help it.  If you roll 4 each side of the card has a door. To represent each door secretly place a card face down to represent the new rooms and their hidden contents.

To Scale encounters I like to use a character count modifier represented by “C”. For example: Skeletons Cd6. This means roll a d6 for each character in the dungeon (even if the party is split). 

Here’s an quick example deck Its roughly set for a group of 4 characters around level 5, it scales a some for character count but is not fair for a single character, “its dangerous to go alone”. C is short for Character count, it helps to scale for the number of characters.


Castle of the Damned

2♠ Zombies! Cx2 
3♠ Bat Swarms xC – Disadvantage to surprise them.
4♠ Giant Rats Cd4 –  On Death 35% chance to reveals as a Wererat at full HP same initiative – Disadvantage to surprise them.
5♠ Fade to Gray – Wraiths xC + Specters D6
6♠ Skeleton Cavalry – A Large Room with 2C Skeletons Mounted on Skeletal horses. If a Mounted Skeleton moves 20′ in a straight line before attack they have advantage and automatically critically hit.
7♠ Ghouls 2C + Giant Bats xC – Disadvantage to Surprise them.
8♠ Toxic Zombie Hoard -Cd6 Zombies, if they pass Undead Fortitude all adjacent creatures take d6 poison damage.
9♠ Court of the Damned – D4+C Vampire Spawn – Spawn roll D20+6 vs Characters passive perception to surprise the party.
10♠ Skeleton Defenders Cd3 Skeletons with heavy armor, shields (+4 AC) and spears.
J♠ The General – Wight Lord (125hp [physical dmg resistance], AC 16 Wight with Lance) mounted on Hydra with C heads, and C Zombies
Q♠ Banshee – The doors magically lock behind you until the Banshee is defeated. Knock or other powerful magic is the only other out.
K♠ Devourer + Zombies xC
A♠ Vampire Lord – If you have the A♢ or destroyed the Vampire’s resting place (J♣) the vampire cannot use its Misty Escape

2♣ Pit Trap – First 2 characters in marching order may make perception check DC 20 to spot the trap, dwarves have advantage. If they fail, in marching order each character makes a DC20 Dex save to avoid each following character gets a +2 (its easier if you were at the back). Falling is 2d6 bludgeoning + d12 piercing on a failed save. If all characters fall the party gets a DC 15 Group Athletics check or they die in the pit.
3♣ Hypnotic Mirror – DC13 Wisdom Save or turn against the party till unconscious (players who turn against the party are on the same team).
4♣ Dead Bodies – Wisdom save DC10 or disadvantage on next initiative
5♣ Necrotic Ward – A character proficient in Arcana or through the use of a spell may read the magic runes and know them for what they are, otherwise all characters immediately make a DC14 Dexterity save or take 8d6 Necrotic damage, half as much on a successful save. 
6♣ Haunted Chapel. 3 ghosts emerge as the party enters. May be be dismissed with DC20 Religion check (1 Chance)
7♣ A Kenku Assassin fires a poison bolt at the character at the back of the marching order unless a character has a passive perception of 30+. A Neutral or Evil character may attempt a DC13 Persuasion check to gain it as a follower.
8♣ What is Lost – A room collapses, DC10 Dex save to retreat or take 2d12 damage. Draw cards until you draw a red card, discard it. Place the rest on top in random order.
9♣ Flooded Grave – A snake filled pool of water stretching 60 feet leads to any exits this room has. Characters wearing medium or heavy armor must make disadvantaged athletics checks for each turn in the water or they cannot move further that turn, additionally those in heavy armor suffer d12 damage unless they have water breathing. Each character that ends its turn in the water is pursued by 2 snakes and each makes a +0 attacks each causing d12 poison damage. A character may attack snakes with disadvantage any damage slays, and you will not be further pursued unless you re-enter the water. You may help adjacent allies attack their snakes.
10♣ A Portcullis Slams down behind you. 50 Cumulative Strength to Break or discard a Rest Card to disable. You cannot back track until you defeat this challenge and you are trapped if no further rooms are generated.
J♣ Vampires Resting Place – If you have drawn the A♠ at any point in this game you may destroy the Vampires resting place after facing a Helmed Horror, otherwise a character must pass a DC18 Intelligence Check to do so, if you do no destroy the resting place shuffle it back into the deck. The Helmed Horror has a 60% chance to be immune to specific spells cast on it of level 2 or higher, max 3.
Q♣ Entropy – Draw a card, if its red make a DC 15 Group Intelligence Save to play it, otherwise discard it.
K♣ Impending Doom – Draw cards until you have 2 black, stack them, you must face each of them in order before proceeding. Place any red cards drawn on the bottom of the deck.
A♣ Cohort of Evil – Combine next two Encounters (Stack 2 cards as one room) draw cards till you get 2s. Place the rest on top of the deck in random order.

J Milestone Level Up (Optional)

What’s left? To complete this deck I’d like to add room descriptions for more of the encounters, and obviously lots of playtesting along with tightening up the rules.

Extra Rules

All characters may start with inspiration.

Unless otherwise stated NPCs make or fail saves the as their leader outside of combat.

Options

Secret Doors If a room must connect to another room this means the door you just found is a secret entrance. If you can enter an unexplored room through a secret entrance you gain advantage on the surprise check. You may mark these with a token such as a penny.

Treasure Face cards which are combat encounters generate treasure hoards when they are completed. Number cards generate regular treasure.

Alert Level If you flee from combat with intelligent creatures 4+ there’s a 50% chance the entire dungeon will go on alert. This grand disadvantage to all surprise checks.

Companion Limit A character may have companions of the same alignment equal to 1+Charisma Bonus.

Exit When you draw the last card of the deck if it is a room with more than 1 door it is a dungeon exit.

Fleeing to flee from a combat encounter discard a red card then shuffle the current encounter back into the deck. Keep in the mind the secondary consequences of shuffling.

Difficulty Setting to reduce the difficulty especially if you choose to not shuffle harder encounters to the bottom of the deck you may start with a number of rest tokens which function just like the cards.

Making Your Tabletop RPG GM-less… and Probably Random.

Intro: GM-less means running a game where everyone is a player and there is no master in control. There has been much written on this topic and many approaches, I will outline the approach I have created for my group, its objectives, and the unexpected magic that sprung from it! If you have not already guessed it, yes, I am a GM, and fairly prolific at this point! I run two games a week for large groups and have been running at least a game a week for roughly… 6 years. And I love doing it! Bla, bla, more in bio (coming soon).

Note: Okay, but first, this is the sites first post so I want to just say something about writing style. I favor brevity in writing, so I’ll keep my posts short and to the point. Well then you might ask, “is blogging really something you want to do”? To that I’d say it’s less about writing fluffy articles and more about getting out actionable information with limited page space in this virtual zine. Our other authors will have a differing approach. Who knows… I can already feel myself getting long winded.

Background: The very idea of a GM-less game seems to be ever present in the thought-palace of RPG gamers. We want to have the rich experience of an adventure amid a well crafted campaign without the work and, well… or do we? There’s a lot of pieces to an RPG which one could automate, and it likely depends on the group as to which they’d choose.

The random dungeon concept is nothing new, there are likely hundreds of systems out there for this. Its related to the GM-less concept but can also exist wholly outside of it. There’s a system included at the back of the D&D 5e Dungeon Masters Guide, there are rollable tables online, donjon has an excellent system, there are decks of cards, the list goes on. Some of these systems tie the environment (usually a room) to it’s contents, others may have a loose theme with thematic encounters which can occur in a variety of thematic locations. I wanted to go a step further and ensure nearly anything could happen.

How do I conceptualize this? How do you tie together a seemingly absurd mix of random encounters? Its all in the narrative! Its about the story we tell ourselves, depending on your preference these things do not have occur in fixed time and space, that notion itself can be as random as the encounters, if you can take that leap. I picture my GM-less random system as though its being read from ancient manuscripts and historical accounts pieced together loosely to make a saga. Its up to us to connect the threads or leave it a mystery. I’m getting ahead of myself.

THE SYSTEM
Here’s how you do it, step by step.

Given you have a platform, in person or online, a group of players and all the normal things you need to play your RPG typically (you know like characters and dice) then you’re good to go, with just one additional piece of the social contract.

You’ll need some number of players willing to rotate responsibility for administrative tasks (moving monsters etc) and executing the steps below, ideally more than one player, as many as possible really but you may want to leave out the new person if they are still learning how to play.

On your turn you’ll do the following.

  1. Generate Encounter: There are many ways to do this. I use rpg tools this site gives a CR appropriate encounter with an optional description of motivations, its a great place to start if you’re testing out my system. You can generate a few and pick one, or however your group agrees to do it.
  2. Set the Scene: Whether you’re playing theater of the mind, on a wet erase mat, or using an online tool, you’ll want to roughly sketch the area and drop in features as you see fit (always add a bookcase which can be knocked over). You don’t have to use the prompt from step one, practice thinking on the fly, improv baby!
  3. Motivations: Characters and Monsters need goals. Give player characters a reason to be here and an objective. In the simplest terms it could just be: you need to defeat these enemies, but you’ll get more creative as time goes on. As for monsters, do the same.
  4. AI Tactics / Monster Behavior: we are fortunate as a community to have this resource The Monsters Know What they are Doing but its not the only option. D&D 4th edition Monster Manuals provide monster roles and tactics, they are very informative!
  5. You can do ANYTHING: initially this may sound like a boring combat generator. Hey, I love combat, doesn’t every role player? Seriously though. I’ve literally taken a page from the Mythic: Game Master Emulator to account for anything the players can imagine from the game scenario. “Don’t dream it, be it.” Its quite simply really. Typically you’ll just set chaos to 5 on the chart below, decide on the odds then roll it! Are there burning sconces here? Seconds later you have your answer. I suggest having the entire group decide or vote on odds, you can always take the average. Full Mythic Emulator PDF

6. Generate Treasure: You can use the DMG or one of the many online treasure generators. Again donjon is great for this. Play around with generating treasure hoards, its so fun!

7. Between Encounters: I use a playing card system to generate chances for short or long rest. It’s not a science yet but basically pull from a deck of standard playing cards. Diamonds are short rests, face cards you can save to use later, number cards are immediate. Hearts are long rests, same concept. Jokers can be use for leveling if you want to do milestone. You can do all sorts of stuff, I’ll write an article on this later. You can make cards dictate the challenge of the next encounter or even dictate the type of encounter: NPC, City, Shop, Treasure, etc. This in part will help for the timeline and narrative that stitches these encounters together. Here’s the full random Card Deck Dungeon I’ve been prototyping, it inspired the method.

8. Get Inspired (optional): If the story so far inspires you to come up with an encounter to insert into the mix, then just do it! Also, feel free to insert pre-made encounters from any source into the mix in any fashion the group is okay with!

Experiments: To help reinforce that this is a group effort I plan to experiment with having a player other than the one currently running the encounter actually execute the enemy actions.

Bonus: Here’s a magic shop generator: https://5emagic.shop/generate and for your entertainment: Weak Magic Items for 5e https://www.lordbyng.net/inspiration/

Yes, I’m a simulationist. [Future Article Link]

So, my group “tested” this system and the results, were good, but more surprisingly something really great grew from it almost immediately. I’ll explain that in a following post, stay tuned! [Future Article Link]
