How to Play

In Adventure, players work together to overcome challenges, battle ferocious monsters, explore new worlds, discover hidden treasures, and, hopefully, save the day.

How it works

The game follows a simple pattern.

  1. The Game Master (or GM, the person running the game) describes a situation.
  2. The player or players state what they want to do.
  3. The GM describes what happens.

The most important phrase in Adventure is, “What do you do?”


GM: “Before you lies a bridge. There are boards missing in places, and the ones that remain appear old and rotted. What do you do?”

Player: “I try to walk across, carefully checking for loose boards as I go.”

GM: “As you’re walking across, one of the boards starts to break under your feet. As you scramble across, the entire bridge begins to collapse. What do you do?”

Player: “I try to jump to the other side before the whole bridge falls down.”

GM: “You push off the breaking board with all of your might, catching the ledge with your fingers and hoisting yourself over the edge. The bridge falls into the chasm below you. But as you do, your sword falls out of your hilt and drops onto a ledge about 20 feet down. What do you do?”

What you need to play

  1. A set of dice. Adventure uses polyhedral dice: D4, D6, D8, D10, and D20. If you don’t have any, you can use the D6 variant detailed below or roll digital dice.
  2. Character sheets. You can print them out from the downloads page.
  3. Your imagination. The most important part!

You might want to keep a pen and notebook handy, but it’s not at all required to play.

Dice are described using D* naming, where * is the number of sides the die has. For example, a standard six-sided die is a D6. A die with eight sides is a D8.

Creating a character

Every player creates a character to play in the game.

The downloads section includes printable character sheets to guide you through the process. You’ll also reference them throughout the game.

1. Picking a class

A class is a bit like a job or way of life.

Each class comes with unique features and abilities. Classes are designed to be customized and tailored to fit whatever kind of character you want to be.

  • Fighter. Skilled with armor and a wide range of weapons, fighters are athletic warriors. ex. Barbarian, Soldier, Samurai, Knight, Superhero
  • Wizard. Masters of magic, wizards can do stuff like shoot fireballs from their hands, teleport, and create illusions. ex. Wizard, Witch, Sorcerer, Warlock, Mystic, Enchanter
  • Druid. Sharing a deep connection with nature, druids can control the elements and even transform into animals. ex. Druid, Ranger, Shapeshifter
  • Rogue. Quick on their feet and skilled at stealth, rogues move in the shadows and operate behind the scenes. ex. Thief, Robin Hood, Ninja, Spy
  • Bard. Talented and outgoing, bards weave a touch of magic into every performance. ex. Musician, Storyteller, Fire Breather, Diplomat

2. Picking a name and ancestry

Your ancestry is your background and the type of creature you are.

You can be a human, of course. But you can also be any other sort of fantastical creature you’d like: an elf, gnome, fairy, dragon, and more. The only limit here is your imagination.

And your name is, well… your name!

3. Assigning your stats

Just like in real life, every character is good at some things and not-so-good at others.

Stats are broad categories that you assign a number value to. Positive numbers are things you’re good at, and negative numbers are things you bad at. The higher the number, the better you are at that thing (and vice-versa).

Your stats affect how easy or hard certain tasks are for your in the game.

  • Strength (STR). Athletics, Feats of Strength
  • Dexterity (DEX). Acrobatics, Slight of Hand, Stealth
  • Constituation (CON). Endurance, Stamina, Concentration
  • Intelligence (INT). Knowing Things, Book Smarts
  • Wisdom (WIS). Perceiving Things, Street Smarts
  • Charisma (CHA). Deception, Persuasion, Performance

When you start the game, take the following numbers and assign each one to a stat: +2, +1, +1, 0, -1, -1.


Quill is a Gnome Bard with the following stats:

  • STR: -1
  • DEX: +1
  • CON: +1
  • INT: 0
  • WIS: -1
  • CHA: +2

Based on these stats, he’s very charismatic and quick on his feet, but he’s not very strong. He has a low WIS score, so he’s also pretty aloof and spacey.

4. Pick your features

Every class starts with a handful of features, skills and traits that make you unique.

Classes that know magic—the Wizard, Druid, and Bard—also get to pick one or two additional Advanced Features at the start.

You can also create your own Ancestry Feature. This is a feature that relates specifically to your chosen ancestry. A fairy might have the ability to fly short distances. A dragon might have a fire breathing feature. A gnome might be able to hide really well.

As you progress in the game, you’ll pick up additional features that let you customize your character even more and give them new ways to play.

5. Pick your gear

Every adventurer needs gear.

In addition to unique features, every character starts the game with class-specific equipment. Bard’s get an instrument. Fighters get to choose from an assortment of weapons. Wizards get a spellbook.

The character sheet includes a list of options for each class. You can also choose a personal trinket, something small and unique to your character. Totally optional.

Rolling dice to learn what happens

For most player actions, what happens is decided by rolling a 20-sided die, called a D20.

To determine the outcome of an action, a player rolls a D20 and adds one of their stat modifiers based on what they’re trying to do. The GM will tell you which stat to use.

(For negative stats, subtract the number from your die roll instead of adding it.)

Roll Outcome What it means
18+ Success The player’s action works as planned
9-17 Partial Success The players action works, with a cost
8- Failure The player’s action doesn’t work

Don’t have a D20? You can roll digital dice here.


The player is trying to convince a wealthy noble that they’re a distant relative. This is an act of deception. They roll a D20, and add their CHA stat.

  • On 18 or above, the noble believes them, offering them a room in their palace and a feast in their honor.
  • On a 9 to 17, the noble reluctantly believes them, but secretly sends someone to look into their background.
  • On an 8 or less, the noble becomes angry, and has them arrested.

The player is trying to run across a collapsing old bridge. This requires dexterity. They roll a D20, and add their DEX stat.

  • On an 18 or above, they run across and leap safely to the other side just as the bridge collapses.
  • On a 9 to 17, they leap safely to the other side, but drop their weapon into the canyon.
  • On an 8 or less, the bridge collapses under their feet.

D6 Variant

If you don’t have polyhedral dice (and don’t want to roll digital dice), you can use a variant of the rules that uses only D6 dice.

  • Instead of a D20, roll one D6 and multiply the result by 3. Then add the relevant stat modifier.
  • Instead of damage rolls, use average damage amounts based on damage die size.


  • You roll a 3. Multiplied by 3, it becomes a 9. You succeed, with a cost.
  • You roll a 1. Multiplied by 3, it becomes a 3. You fail.
  • You roll a 2. Multilpied by 3, it becomes a 6. But after you add your +3 DEX, it becomes an 9. You succeed, with a cost.

Best Of & Worst Of

You might have better or worse odds of succeeding in action based on your current circumstances. Adventure uses Best Of and Worst Of die mechanics to account for that.

  • Best Of. Roll two D20 and take the higher number.
  • Worst Of. Roll two D20 and take the lower number.

Conditions that provide an advantage give you Best Of on die rolls. Conditions that hinder you give you Word Of on die rolls.


Best Of:

  • You try to sneak past a guard who’s partied too hard the night before and fallen asleep
  • Your ancestry grants you superb jumping ability, and you’re trying to leap across a gap

Worst Of:

  • You sustained a nasty gash in battle that’s become infected, making it harder for you to hold a weapon
  • An evil wizard charmed you
  • The creatures you’re facing are so terrible that they frighten you


Combat in Adventure works just like any other player action.

  • The player says what they want to do, rolls a D20, and adds a stat
  • The GM describes what happens as a result

Attacks with a melee or up-close weapon (swords, axes, and such) use the STR stat. Ranged or far-away attacks (using a spear, bow, and so on) use the DEX stat. Similarly, blocking uses STR, while dodging uses DEX.


The player is trying to hit an ogre with their sword. This is a feat of strength. They roll a D20, and add their STR stat.

  • On 18 or above, the sword hits, causing the ogre to scream and stumble back a few feet.
  • On a 9 to 17, the sword hits, but the ogre swings at them at the same time slams its fist into their shoulder.
  • On an 8 or less, the sword misses, slamming into the ground beside the ogre.

A troll throws a giant boulder at the player, and they attempt to jump out of the way. This requires dexterity. They roll a D20, and add their DEX stat.

  • On an 18 or above, the jump out of the way, and the boulder bounces off into the distance.
  • On a 9 to 17, they leap out of the way, but the boulder catches their sword and knocks it 20 feet away.
  • On an 8 or less, the boulder slams into them before they can jump out of the way.

Hit points

Every character and creature has a pool of Hit Points (or HP). Hit Points represent a creatures overall health.

Your characters Max HP is determined by adding their CON stat to a base number that varies by class (as indicated on your character sheet).

Whenever a character or creature takes damage, points are subtracted from their Current HP. When their HP reaches 0, they’re knocked out, and remain that way until another party member revives them.

A character’s Current HP can never exceed their Max HP.


A rogue has a CON of +1. Their character sheet says their Max HP is 6 + CON, so their Max HP is 7.

Their Current HP starts at 7 as well. Then they get hit with an arrow and take 2 points of damage. Their Current HP is now 5.

Calculating damage

Every character sheet specifies the damage die used by that class.

Whenever your character successfully hits a creature, roll your damage die to determine how much damage is dealt.

Some weapons provide a damage modifier, additional damage dealt above what’s rolled. For example, a warhammer deals +1 damage. When using it, you would add 1 to whatever number you roll.


A fighter swings his warhammer, striking a goblin in the chest.

The fighter’s damage die is a D10. They roll a 7, and the warhammer provides an additional +1 damage. The GM subtracts 8 from the goblin’s HP.


Armor and shields provide protection against attacks.

When a character or creature receives damage while wearing armor, they subtract their armor value from the damage received before subtracting it from their HP.

Most protective gear has an n armor rating. You can only wear one piece of armor of this type at a time. Some protective gear, like shields, are additive and have a +n armor rating. This can be added to whatever your current armor value is.

Armor labeled clumsy is tough to move around in, and imposes Worst Of on all STR, DEX, CON, and spellcasting rolls.


The fighter is wearing chain mail (1 armor) and carrying a shield (+1).

A giant slams his club into the player, doing 5 points of damage. The player subtracts 3 from their Current HP. The armor prevented 2 HP of damage.


As an adventurer, you’re going to take damage from time-to-time. Fortunately, you can heal yourself in a variety of ways.

  • During a short rest (1 hour or less), you can recover one damage die roll of HP
  • During a long rest (8 hours or more), you recover all of your HP
  • Using tools like bandages, an herbalism kit, or healing potion

When you roll a damage die or use healing tools, add the amount of HP healing back to your Current HP (up to your Max HP).


Healing with Damage Dice
Your Current HP is 3, and your Max HP is 14. You roll a D10, and get a 6. Your new Current HP is 9.

Healing with Potion
Your Current HP is 6, and your Max HP is 8. You drink a Healing Potion, which heals 7 HP of damage. Since your Max HP is 8, your new Current HP is 8. The remaining 5 HP of healing is lost.


Adventure is a cooperative, team game. The more you work together, the more likely you are to succeed.

  • For group tasks, like trying to cross a river or sneak into a castle, if at least half of the party succeeds, everyone does.
  • For individual tasks, if you can reasonably assist a teammate, they get Best Of on their roll.

Buying & Hauling Stuff

The common currency in Adventure is Coin.

Every character gets a few starting coins, noted on your character sheet. As you go on adventures, you’ll find or earn more. You’ll also acquire treasure, magical items, and gear.

There’s a list of common items, and their prices and weight, on the equipment page.

Buying Stuff

You can use Coin to purchase things you need, including weapons and armor, supplies, lodging, and more.

In populated areas, like villages and cities, you’re likely to find everything you need at reasonable prices. In more remote areas, some items might be harder to find, not available at all, or more expensive than typical market rates.

Item Weight

There’s only so much stuff you can carry with you before it becomes too heavy.

Adventure uses a simple system for calculating how much stuff you can carry. All items have a Weight. The Max Load your character can carry is determined by adding their STR stat to a base number that varies by class (as indicated on your character sheet).

When the weight of the stuff a character has with them exceeds their Max Load, they’re encumbered, and get Worst Of on all STR, DEX, CON, and spellcasting rolls.

This is totally optional. Feel free to drop this rule from your games if you don’t like it.

Character growth

All adventurers start the game at level 1. As your character goes on adventures, they’ll gain new experiences and pick up new skills.

Whenever the party does something particularly meaningful of awesome, the GM should level up the party, increasing your current level by 1.

When you level up…

  • Select a new feature from the Feature List on your character sheet
  • At odd levels (3, 5, 7, and so on), increase a stat of your choice by 1, up to a max of 5


Your party successfully snuck into the old wizard’s tower, and retrieved the magical black pearl just as the tower collapsed into the ocean. Along the way, you fought monsters, overcame dubious traps, and raced a crew of pirates.

You’re currently a level 2 druid. The GM decides to level you up to level 3.

You pick a new feature, Tangle of Vines, from the Features list. Because you hit an odd level, you also increase your WIS stat from 3 to 4. WIS is your spell stat, so you want to maximize the likelihood that your spells work.

House Rules

House rules are strongly encouraged in Adventure. Here are some ideas you may want to adapt to your game.


For added fun, characters can have a pet that accompanies them on their adventures and helps them along the way. This can add a fun dimension to the game.

Pets can be small and sensible (a cat, dog, or woodland creature) or large and absurd (a dinosaur, dragon, or elephant). A player’s pet can be used to get them out of a tough situation, as a weapon in battle, or just for added flavor and interest in role playing.


Quill didn’t expect the rope to snap on the sharp edge of the well, or he never would have come down here by himself.

Fortunately, he brought along Geoffrey, his pet rat. He instructed Geoffrey to scurry up the wall and find help.

Roll to see what happens.


If you have an adventurer who loves to build things and has a big imagination, tinkering is an awesome special skill. A tinkerer can build small creations from bits of scrap metal and wood.

Here’s how it works.

  • Tinkered items can be robotic toys, weapons, tools, and more.
  • Tinkered items are small and fragile, and stop working after a few turns.
  • Only one tinkered item can exist at a time.
  • The parts from a tinkered item can be reclaimed to build another (either after it break, or when the adventurer decides they’d like to build something else).

The Game Master may choose to have the adventurer first acquire a tinker kit: gears, bits of scrap metal, and some small tools from a shopkeeper in the game.
