Design Principles & Overview
Collaboration
Conductors facilitate the game and make rulings. Players engage with the fiction. Together, they create interesting stories.
Player Choice
Conductors share as much information as possible. Players solve problems and avoid risk through innovation and clever problem solving. Every choice matters.
Growth
OnO lacks a leveling mechanic. Character growth emerges through equipment, encounters with strange magic, and the Death Cycle.
Death Cycle
Souls grow and change (for good or ill) through death and rebirth. Potential Boons (and Curses) incentivise players to invest in even the most statistically deficient characters.
Genre Collage
OnO juxtaposes varied setting and characters in the style of shows like Infinty Train and video games like Kingdom Hearts.
Aspirations & Past Lives
Souls strive toward their aspirations and deal with the consequences of their Past Lives.
Balanced Fun, Unbalanced Numbers
OnO prioritizes fun and flavor over balance.
Roll for Risk
Players roll Saves only in the face of risk.
Modularity
Conductors pick and choose the mechanics and systems they wish to use and which they will ignore.
Principles for Conductors
Information
- Provide information freely and readily.
- Always encourage players to ask questions.
- Never hide information behind a roll.
Preparation
- Use random tables and generators to develop situations, not stories or plots.
- Give NPCs motivations, flaws and drives.
- Draw on PCs needs and wants to create opportunities and obstacles.
- Play to find out what happens.
Choice
- Clarify player intent before dice are rolled.
- Offer difficult decisions.
- Explore the consequences (good or ill) of strong decisions.
Danger
- Telegraph danger to players. The more dangerous, the more obvious.
- Put traps in plain sight and let players take time to figure out a solution.
- Make death a constant threat.
Failure
- Failure pushes the story forward.
- Foster a table where success and failure are equally exciting.
- Elicit complications or twists from players.
Dice of Fate
- When randomness is needed, roll 2d6.
- 1-6: Bad Result / 7-9: Mixed Result / 10-12: Good Result
Principles for Players
- Ask questions often.
- Attributes and saves represent narrative luck. They do not define your character’s body or mind.
- Fighting is a choice and rarely a wise one; consider whether violence is the best way to achieve your goals.
- Look for (and create) non-combat solutions to problems.
- If you must fight, stack the deck in your favor and retreat from bad odds.
Player Characters (PCs)
1. Ability Scores & HP
Roll 3d6 for each Ability Score. 10 is average.
- Strength - Fighting, fortitude, and toughness.
- Dexterity - Stealth, athletics, and reflexes.
- Willpower - Confidence, discipline, and charisma.
PCs start with d6 Hit Protection, a measure of their ability to avoid life-threatening Damage.
2. Inventory and Equipment
Inventory Slots
PCs have a number of inventory slots equal to their STR or 10, whichever is higher. (i.e. a PC with STR 8 has 10 slots, a PC with STR 10 has 10 slots, a PC with STR 12 has 12 slots).
One slot for each hand. Additional slots can be flavored however you wish (i.e. a backpack, pockets, etc).
- Most items take up one slot.
- Bulky items take up two slots. Typically two-handed and awkward to carry.
- Small items can be bundled together at the Conductor’s discretion.
Anyone carrying one more than a full inventory (e.g. filling all slots + 1) is reduced to 0 HP.
Designer’s Note: The inventory system in Cairn reduces a PCs HP to 0 when all slots are filled, but my players and I always forget to implement that until they run into something that would go over their limit. This change is intended to turn the mechanic into more of an interesting choice.
Item Tags
Tag | Meaning | –|–| Blast | An attack that hits everything in a target area with damage rolled separately for each affected. | Soulbound | Costs 1 SP to ensure it will be passed to your next life. | Light | Takes up 0 item slots.| Stack # | Up to # can be stacked to a single equipment slots| Bulky | Take up two item slots. Typically two-handed and awkward to carry. | Heavy | Cannot move and attack/use on same turn. | —
3. Aspiration & Past Life
Using the following table, roll for your Aspiration and your Past Life.
Past Life:
- Roll d20+0
- Provides:
- Equipment Package
- [Optional] Past Life Question for flavor
Aspiration
- Roll d20+1
- Provides:
- Advantage on relevant ability Saves
- One item from the matching Equipment Package
All PCs begin with 5 Rations (Light), 3d4 Credits (Light), and a Death Toll(DT) of 1.
Designer’s Note: Death Toll is there to keep the variety of Aspirations fresh and to cut off options like Homonculus which only makes sense as an option for the first roll.

4. Ancestry (Optional)
You may also roll 2d6 for your PC’s ancestry and even the ancestry of their Past Life.
This has no specifc mechanical impact, but it might make sense to let Featherfolk fly, and Man-Spiders climb walls, etc.
Players who prefer a modicum of choice can look at both possibilities for a roll and decide between the options (for doubles, subtract the number from 7 to find a second option). For example, if they rolled 2 and 6 they could then choose between ‘Mothkin’ and ‘Duckfolk.’

[Equipment stuff tk]
Companions & Hirelings
Companions
For small player groups, each player may create one or more Companions. Roll their Ability Scores with 2d6+3 in order and give them d6 hp, a club or sword(d6), and one item from the table.
1. Light Source 2. Crowbar 3. Rope (25ft) 4. Pole (10ft) | 5. Tinderbox 6. Shield (A+1) 7. Natural B+1 8. Amulet (C+1) |
---|
Hirelings
Unless noted, all Hirelings have: 1d6 HP and Ability Score 10.
Job | Cost/Day | Ability Score | Equipment |
---|---|---|---|
Lighter Kid | 1¢ | STR 2d6 | lantern, club |
Mercenary | 5¢ | 2d6 HP | Musket, Sword |
Expert | 10¢ | N/A | Pistol, expertise in a specific area |
Option: Rather than set rates, Hirelings can be priced at a share of whatever treasure the party obtains. However, this probably requires the Hireling be convinced of the possibility of treasure in the first place and more seasoned Hirelings may expect an advance before venturing with the PCs.

Equipment
Mostly don’t worry about it but Companions and Hirelings can both use this table for item slots:
STR ≤ 10 | 10 slots |
---|---|
STR >10 | A number of slots equal to your STR Score - 5 |
What Do You Need to Know?
Saves
Roll a Save to avoid danger from a risky action or situation.
Roll d20. If the result is equal to or under the Ability Score: you pass. 1 always succeeds. 20 always fails.
Make difficult Saves with Disadvantage (roll twice, take the worse result). Make easier Saves (and those related to your Aspiration) with Advantage (roll twice, take the better result).
Combat, Damage, and Death
Combat
At the Start of Combat, each PC makes a DEX save for a chance to act before their adversaries.
- Success: The PC may act before their opponent.
- Failure: The PC does not get to act before their opponent.
After that, order proceeds with PCs acting, then adversaries.
The game typically plays without strict time accounting. If timing is necessary, use 10 second rounds to keep track. A round is comprised of character turns. During each turn all actions, attacks, and movements take place simultaneously.
On Your Turn:
- Move up to 30ft
- Perform one Action
- Attack
- Use an Item
- Make a Save
Attacks
Attacks always hit! Roll the damage die! Subtract the enemy’s relevant Defense!
Enhanced attacks (i.e. high ground) add max die result to damage roll (d6 + 6, d8 + 8, etc).
Impaired attacks roll d4! (i.e. Target behind cover)
Blast weapons can hurt multiple enemies(see [Item Tags link tk])
Damage
To calculate and account for damage, follow these steps:
- Roll the damage die
- Subtract Relevant Defense (STR:Armor; DEX:Balance; WIL:Calm)
Damage is first taken from HP. Damage that reduces a target’s HP below zero decreases a target’s Ability Score. They must then make a Save to avoid Crit Damage.
Additionally, some enemies will have special abilities or effects that are triggered when their target fails a critical damage save.
Damage Table
- HP hits 0: make a save of the targeted Ability
- Paralyzed & Incoherent can be treated with a Full Rest
Damage Type | Ability | Defense | On a Failed Save | Ability reduced to 0 |
---|---|---|---|---|
Physical | STR | Armor | Unconscious | Dead |
Stun | DEX | Balance | Immobilized | Paralyzed |
Stress | WIL | Calm | Roll for Curse | Incoherent |
Curse Table
- Your next incarnation rolls 2d6 instead of 3d6 for their STR. Overrides ‘Carry STR.’
- Your next incarnation rolls 2d6 instead of 3d6 for their DEX. Overrides ‘Carry DEX.’
- Your next incarnation rolls 2d6 instead of 3d6 for their WIL. Overrides ‘Carry WIL.’
- Your next incarnation will have an intensive fear based on the way your current incarnation dies.
- When you die, your body becomes a zombie and attacks your friends (2hp, lunge: d4).
- Your next Incarnation will be a Maggot-kin (sentient swarm of maggots controlling & eating a rotting, humanoid corpse). Maggot-kin cannot have more than 1 HP.
- A spectral hunter has chosen your Soul as a target and intends to consume it. They have your spectral signature and will hunt you mercilessly.
- Your next Incarnation will hunger for the Souls of others. You must feed once a day or become Deprived.
- 2 Curses. Roll twice. (If you get another 10 just reroll it).
- Dissolve into Sea Foam
- Magical Explosions (d10 Burst)
- Lose a limb
- Unfixed Form: roll a new ancestry every day
- All your teeth fall out
- Hands become feet, vice versa
- Ears become eyes, vice versa
- No more bones in you
- You catch consumption (3d6 weeks to live)
- Everyone becomes angry with you
- Your arms dissolve into their weight in coins
Advanced Actions
Advanced Actions
WATCH OUT: Each repeated turns of Blocking and/or Dodging costs 1 HP.
Action | Check | Effect |
---|---|---|
Block | n/a | Armor & Balance x2 this turn. |
Dodge | DEX for each incoming attack | Success: Take no damage. Fail: Take impaired damage. |
Parry | DEX or WIL | Success: Take no damage + free Enhanced counterattack. Failure: Take Enhanced damage. |
Designer’s Note: The addition of these 3 Advanced Actions is meant to give some additional strategic combat options to new players in order to get them thinking about the possibilities. They also enable Souls-like-style victory against insurmountable odds. Just like in Souls games, Parrying is more difficult to pull off and runs a higher risk, but also presents the most forward action and does not cost stamina(HP).
Reactions
When the PCs encounter an NPC whose reaction to the party is not obvious, the Conductor may roll 2d6 and consult the following table:
2 | 3-5 | 6-8 | 9-11 | 12 |
---|---|---|---|---|
Hostile | Wary | Curious | Kind | Helpful |
Morale
Groups require a WIL Save to avoid being routed when they lose half of their total numbers. Groups with a leader may use the leader’s WIL score in place of their own. Lone combatants must pass this Save when they are reduced to 0hp. This applies to opponents and allies but not Player characters. Fleeing to safety under pursuit requires a DEX Save and somewhere to withdraw to.
Recovery
Short Rest: A few minutes of rest and a swig of water recovers all of a character’s lost hp. Resting may waste time or attract danger.
Full Rest: A Full Rest requires a week of downtime at a comfortable location. This restores all Ability Scores.
Deprived: Somebody deprived of a crucial need (e.g. food, water, or warmth) cannot benefit from Rests.
Death Cycle
Uh oh, you died… Congratulations and goodbye to you! Wherever will your Soul go next?
Increase your Death Toll (DT) by 1.
Designer’s Note: Souls are not bound by the same laws of time as a mortal body. Your Soul’s next Incarnation is likely already alive and moving through the world. In fact, they’re about to show up and immediately join the party to reduce your downtime as a player!
When a PC dies, their Aspiration becomes their new Past Life and provides a full equipment package. Roll for a new Aspiration (d20+DT) and take one item from the Equipment Package.
Before your new Incarnation arrives, your Soul has some choices to make.
Earn SP
Answer these questions about your character, hitherto referred to as ‘the deceased’:
- Did the deceased save someone else from death?
- Did the deceased loot a memorable treasure or recover loot from the corpse of one of their Past Lives?
- Did the deceased overcome a notable threat or solve a community problem?
- Did the deceased avenge the death of one of their Past Lives?
- Did the deceased express their beliefs, drives, ancestry, Past Life, or Aspiration?
- Did the deceased learn something new and important about the world?
For each “yes” mark 1 SP.
Designer’s Note: The purpose of these questions is to encourage investment into characters. Simply running subsequent characters off a cliff is not going to result in many (if any) SP so it is in player’s best interest to invest in a character and a campaign even with the post-death rewards and high-lethality.
Spend SP
Select a number of Boons. Each Boon costs 2 SP.
- Carry on your STR score to the next Incarnation.
- Carry on your DEX score to the next Incarnation.
- Carry on your WIL score to the next Incarnation.
- Carry on your max HP and (roll d6 to increase it for a max of 12*)
- Carry an item from your past life.
- Eliminate a Curse.
Optional: For each Boon chosen, choose a trait or mark that your next Incarnation will inherit (i.e. a birthmark, a scar, fear of the thing that killed you, etc).
* If spending 1 SP as an antique boon, only carry on the score. Carrying and rolling to increase costs the full Boon price of 2 SP.
Antique Boons
If you purchased any Boons the last time you died, you may either spend 1 SP to take that Boon again OR you may leave it up to fate. For each Antique Boon, roll d12. If you roll a 1, the Antique Boon is lost. If you roll anything else, the Antique Boon remain with your Soul.
Curses
For each Curse which you stand to inherit, you may spend 2 SP to dispel the Curse, alternatively you may leave it up to fate. Roll the die indicated on the table. If you roll a 1, the Curse is dispelled. If you roll anything else, the Curse remains.
Your Old Body
While adventuring, you might cross paths with the corpse of your Past Life. In that instance, you can loot the body. Any items retained via boon or from your new character’s starting equipment is missing. Roll a luck check for each of the remaining items to see if it has been looted or gone bad, etc.
Additional Content
Magic & Oddities
Spells
Spellbooks contain a single spell and take up one slot. They cannot be transcribed or created; instead they are recovered from places like tombs, dungeons, and manors.
Spellbooks sometimes display unusual properties or limitations, such as producing a foul or unearthly smell when opened, possessing an innate intelligence, or being legible only when held in moonlight.
Spellbooks will attract the attention of those who seek the arcane power within, and it is considered dangerous to display them openly.
Scrolls are similar to Spellbooks, however:
- They do not take up an inventory slot.
- They do not cause fatigue.
- They disappear after one use.
Casting Spells:
- Each morning, a PC with a spellbook may roll to replace their current spell with a different one.
- Casting a spell uses a single action and causes 1 Fatigue.
- Given time and safety, PCs can enhance a spell’s impact (e.g., affecting multiple targets, increasing its power, etc.) without any additional cost.
- When deprived or in danger/combat, the spellcaster makes a WIL save to avoid ill-effects (Stress damage, additional Fatigue, injury, etc). (A critical success can either enhance the spell or negate the Fatigue cost)
Spell List
- Roll for Spell Form
- Roll for each term.

Using an Oddity
A character can use an Oddity’s power as a normal action, though some Oddities ask for something in return.
Oddities are objects that house all sorts of strange and mystical powers. The power of an Oddity is palpable, even to an otherwise ignorant individual. However, determining how that power manifests may take some experimentation.
Oddity List
11. Umbrella with a Green Jewel Eye on the Handle. Activation: Open it. A high-pitched buzzing. A horrible rattle of scales and wings lined with hundreds of writhing stingers. The thing (3 HP, Wrap: d8 physical) attempts to slurp up the user and fly off. |
---|
12. Metronome. Activation: Set it ticking. All who can hear it take 1 Stress damage per tick. |
13. Plastic Whistle. Activation: Play the noise into the receiver of a phone or other coms device. Allows the user to make calls across Scales. |
14. Human Skull. Activation: Hold it aloft and speak. Significantly amplifies the user's voice. |
15. Paint and Brush. Activation: Paint a door onto a wall. A successful DEX save allows anyone to use the door. Anyone who fails walks into the wall and looks silly for it. |
16. Frying Pan. Activation: Use it as an umbrella or shield. Blocks all precipitation or Blast damage. |
21. Crimson Scythe. Activation: Attack with it. The target gets -1 SP after their next death. The user gets +1 SP after their next death. |
22. Bloody Armor. Activation: Wear it. The ghost haunting the armor reveals itself. +2 armor but take an additional 1 Stress Dmg every time you take stress damage. Removing the armor incurs the wrath of the ghost (5 HP, 3 Armor, 12 WIL, Ghost punch: d6 Stress). |
23. Roman Candle. Activation: Light and fire it. Causes the room it is in when it goes off to collapse. If outside, causes the ground beneath it to collapse into a sinkhole. Either way: DEX save or 1d8 Stun damage. |
24. Thermostat. Activation: Adjust the temperature. Changes the temperature in a 5-foot sphere around it to match the settings. |
25. Magnifying Glass. Activation: Kill an insect by focusing light through it. Creates a pillar of burning light that opens a gateway to another Scale. Can travel through its own gateway. |
26. Chess Pawn. Activation: Carry it into 6 other rooms. Transforms into a Chess Queen, doubles holder’s movement speed. |
31. Cymbals. Activation: Hit them together. Anyone listening hears something unique and personally distressing. 1 Stress damage. |
32. Star-Shaped Fruit. Activation: Two or more people eat from it. If two people share one, their destinies become intertwined. They'll remain a part of each other's lives no matter what. |
33. Pliers. Activation: Use it to remove one of your own teeth. Deal damage to one enemy equal to the user’s WIL score. WIL save or fall unconscious. |
34. Scissors. Activation: Cut someone with them. Target makes a WIL save or is instantly reduced to 0 STR. |
35. Paper Lantern. Activation: Light it. Produces 20ft of magical darkness. Anything invisible becomes visible against the black backdrop. |
36. Femur. Activation: Hit anything with it. Makes noise like a xylophone being played. |
41. Service Bell. Activation: Ring it. Opens a pocket dimension with 5 item slots. Anyone who hears the dinging makes a WIL save or becomes violent toward the user for 1 round. |
42. Sunglasses. Activation: Wear them. Outside at daytime: the Conductor rolls all Reaction rolls with advantage. Any other time: Conductor rolls all Reaction rolls with disadvantages. |
43. Ball of Yarn. Activation: Loop the string in a cat’s cradle configuration. Reveals a gateway to another Scale. Cannot travel through its own gateway. |
44. Capchamon Card. Activation: Place it on a flat surface. Summons a Zoink(Part pig, part mouse, part dragon. 2 HP, Smash: 1d4 physical, Zap: 1d6 Stun.) to fight for the user. The Zoink dissapears at the end of battle and the card returns automatically to the user's inventory. Can be resummoned once it dies or dispells but never more than one at a time. |
45. Fish Hook. Activation: Push through the skin of a dead body. The body becomes an obedient puppet (2 HP, maim 1d4). |
46. Ancient Obol. Activation: Holder dies. The coin disappears and the user earns 1 free SP. |
51. Electric Guitar with Whammy Bar. Activation: Play a chord and use the whammy bar. All who hear the exciting sound have +1 Balance for the duration of the sound. |
