ONCE (A Worldbuilding Game)

This is a small worldbuilding game I made. There is a document with laid-out rules if you click the image below or click here. Additionally the rules are laid out in plain type in this post.

ONCE Rules
(Art by Ferenc Pinter)

 

Each player selects one book they own. The book can be anything, as long as it has a somewhat substantial page count it will work.
Books with poetic language work well here, although lyrics, prose, and even textbooks have been used.

Each player defines a region of the world. All a region needs is three things - a name, what it looks like, and what it is known for. Keep the description brief. Do this until at least three regions have been defined.  
Eg. Ulong-Sainte. Coastal houses overlook a red sea. It is known for its masterwork boats, some of the only able to cross these waters. 

Each player asks a question starting with “of another player’s region. The question must start with “What”. The player who made that region gives a brief answer. If they need inspiration for the answer, they may flip to a random page in their book for inspiration.
Eg. "What plagues Ulong-Sainte?" - Frogs. Ulong-Sainte has an excess of frogs that nobody knows what to do with.
  
Pick a player to take the first turn of the game. The game may be stopped at any point. It is recommended that at least one player takes notes.
Alternatively, pick whoever was the last person at the table to touch grass. 

Each turn, a player asks a question of another player. This can be anything, as long as the question:

• Begins with “Why”. Questions of this nature often sound childish - this is good. Discard your shame, embrace curiosity. At this table, no question is stupid because no answer is obvious – and nothing is the way it is “just because”.
• Is related to the fictional world being built. The question can build on already established parts of the world, but it can also introduce new elements to the world. If you ask “why is the sky red?”, then this world’s sky is red.

Example questions include but are not limited to:
Why is the sky blue?
Why are all our songs sad?
Why did the kingdom fall?
Why do we exist?
Why do we wage war?
Why do sheep bleat?
Why did aliens land here?
Why do taxes exist?
Why do we sleep?
Why do dogs wag their tail?
Why did we settle here?

The answering player picks up their book, flips to a random page, and reads the first sentence or two they see. They answer, using what they read as inspiration. The answer must:

• Begin with “Once upon a time” and tell a story. This prefix lends itself to telling stories. This is a storytelling game - so do it shamelessly.
• Introduce a character and their motivation in the first sentence. This character is responsible for why what is being questioned is the way it is. If the question is “why do we have a sea,” your answer cannot simply be “Once upon a time, there was a flood,” The answer may include a flood, but someone is always responsible. However, you can personify a flood and make it its own character with agency and motivations.

An example answer includes:
"Why is the sky blue?"
Once upon a time, the folk hero Vandoh was bored after a life of conquest. He struck the white sky until it was bloody. It is still blue with bruises today. 

Once done, the answering player gets their turn to ask a question to a player who has not given an answer this round. A round ends once all players have taken a turn. Whoever is first to ask a question is the last one to answer in a round. 

Optionally, whoever asks the first question in a round may begin their question with “Who caused” instead of “Why”.

Optionally, when players agree on when to start the final round, begin a special round. EVERY player must answer "who caused the end of the world?". The answer must:

• Mention who in the world told you this story. "A radish farmer from Niouh told me..."
• It must reference  a character who has been mentioned before. Build off the existing mythos you and your friends have made. Be biased, use your own suspicions and vibes you get from each character. Connect the dots.

Design Notes
(Art by Ferenc Pinter)

Talking more casually now - I've playtested this a lot and had this sitting in my drafts for a while. I've gotten it to somewhere I'm happy with it - mostly. It still has its quirks.

This game works best in an online asynchronous format. Books are easy to grab, there's less pressure as you flip and think, you get the time to think of an intriguing answer and editorialize a little.

If you run this in person, it helps to have someone knowledgeable in the game - who possesses (at least an image of) confidence. People are far more nervous to participate in worldbuilding games versus more classical tabletop roleplaying games. An assuring presence helps people get around to their answers quicker, and makes them unafraid to choose more interesting answers that will lead to a richer shared world. Additionally, if you run this in person, be lax on the answering format rules. As long as it follows a story structure and gets around in some way, shape, or form to answering the "why", it's probably a valid answer. 

I highly recommend you record what books or other media you used. The source material everybody chooses tends to affect the general tone of a world. It can be very funny to look back on old games and remember how the world took its tone and how the source material played a part in that.

Tangentially, I'd challenge you to ask yourself "who is responsible for this" instead of "what is responsible" the next time you come up with something visually strange or hard to explain in your worldbuilding or setting writing. Asking "who" automatically puts the onus on a person - people have motivations - tightly-held motivations from PCs and NPCs alike lead to interesting gameplay.

That is all, let me know what you think. Have a good one! 

Zero Sum Game (A Magic System)

This is a detailed alternative magic system focused on making magic far more impactful and visceral, along with a few pieces of supplemental material related to the system. Feel free to do with these ideas as you will. 

HOW MAGIC WORKS
(Art by Sergio Toppi)

In The Age Of Timeless Wisdom, magic was taught in schools and cultivated through countless decades of training and study. You do not belong here - you were born red-faced and flailing in a crater that used to be a palace. The Age Of Everflowing Blood welcomes you with open arms and gnashing teeth.

This new, violent age was spurred into existence by a senior thesis which proved the following:

1. Spells are stored in the cranium.
   
   
2. Magic can be harnessed by anybody - contrary to popular belief at the time.
   
   
3. ALL of a wizard's spells can be learned by killing them and consuming their skull. This takes about one night of very careful meal prep.
   

Since this discovery, the socratic methods have been lost in a cannibalistic fervor. Those who had the patience to educate have been eaten by the impatient. The hopes of learning magic in any other way have been dashed against stones of ivory. 

Countless spells have been lost to The Age Of Everflowing Blood. There only exists a single copy of every spell. There is only one Fireball left in existence, one Charm Person, one Healing Word, etc. To know a spell is to have stolen it. To call oneself a wizard is to call oneself a murderer.

 

NOTES ON WIZARDS AND OTHER CULTURES
(Art by Sergio Toppi)

  

Across every horizon it's a dog-eat-dog world. But wolves still travel in packs, and wizards still find power in company. One would assume that a group of wizards would quickly murder one another for a glimpse of power, and they would only be partially right. All wizards have a biological life insurance - once a wizard dies, ALL of the spells stored in their head are cast one last time in random directions and at random targets within sight. This is called a deathrattle. Thus, wizard-murder must be carefully premeditated. You know the old phrase, "if you can't beat them, join them". Wizards form dysfunctional families bound by envy and mutual destruction until one feels superior to the others.

If you look to the safe, shadowy spots of the world, you may see figures huddled against the ashen wind. Hushed tones indistinguishable from the campfire's hiss. They speak of the dragon atop the hill. They speak of a wizard. If you are revealed as a wizard to commonfolk (whether willingly or not), reroll your Reaction Roll - positive results leave them terrified instead of friendly. It is near impossible for magical folk to find true kinship with mortal folk.

Then there are those mortal warriors brave enough to face wizards head-on. Those that believe a good butcher is a careful one, a good wizard is a dead one, and a just man is a poor butcher. When you crush a wizard's skull in haste it will once again perform its deathrattle. After this is done, the skull cannot be crushed or consumed. These acts are reviled by all wizards. They think it no different than bookburning. Plenty of hearts driven by vengeance still stake it all to see sparks fly out of those accursed sockets that have hurt the world so.

Similar to a murder of crows, a group of wizards is called a School. Gluttony is their teacher. Their lessons are cruelty.

FIVE SAMPLE SPELLS
(Art by Sergio Toppi)

 

FIREBALL - R: 120’
Launch a ball of fire that explodes in a 30’ diameter sphere, dealing [SUM] fire damage to everything within. Optionally, choose an extra effect below per MD invested past 1:

1. The affected area is filled with a cloud of opaque, choking smoke that lingers for [SUM] rounds. Breathing beings take [DICE] damage per round spent in the smoke.
2. Double the diameter of the explosion – triple if you take a round to monologue beforehand.
3. Double the amount of MD you’re rolling - triple if you take a round to monologue beforehand. On triples, catastrophic miscast. An effective last resort.

Drago The Cannibal King used his great Fireball to destroy the great libraries of the old mages, ensuring nobody could learn magic through the old methods and securing his place as the dread Cannibal King. His territory is a large crater host to an invisible tower - the air still smolders with burnt paper.

HEAVEN’S MANDATE - R: All Targets In Earshot, D: [DICE] Rounds
Speak a command of [DICE] or less words. Choose one of: Light / Gold / The Pious / Canines to obey your command. If applicable, sentient beings will not obey commands obviously harmful to themselves. Optionally, choose an extra effect below per MD invested past 1:

1. Choose [DICE] extra options to obey your command.
2. The command may be [SUM] or less words.
3. The spell lasts [SUM] minutes.

Neri The Beloved used her Heaven's Mandate to create The Grand Procession, trapped in an endless task of building statues in her image. Her territory is a long trail of tarnished golden statues that are rumored to come to life at night.

DRUID FOG - R: All Targets In Earshot, D: [DICE] Rounds
Conjure a cloud of fog in a 30’ diameter sphere. The cloud is opaque and supernaturally confusing - creatures entering the cloud will exit they way they came in [DICE] rounds. Optionally, choose an extra effect below per MD invested past 1:

1.  Imbue the fog with a drug on your person. Creatures inside must save or be affected by the drug. This save is made with a [DICE] penalty.
2. You can see perfectly through the fog. Those with your permission may pass through the fog unhindered.
3. Ignite the fog with a snap of your fingers, dealing [SUM] damage to all inside and knocking them prone. 

Baldovi The Hermit used his Druid Fog to shroud an entire city he despised in fog, driving all the souls within mad. His territory is this city, his subjects are driven to his bidding by hallucinations within.

CONJURE ARMS - R: Self, D: [DICE] * 10 Minutes
Grow [DICE] extra arms anywhere on your body, under your control. Optionally, choose an extra effect below per MD invested past 1:

1. The arms you conjure are [DICE] * 5' long. You have perfect control of them. They have an unnatural amount of joints. 
2. You may cast this on an object you can touch. The arms are under your control.
3. Conjure double the amount of arms - triple if you give the arms their own control. 

Livio The Monster used his Conjure Arms to abandon his humanity for more arms and more power. His territory is a great castle in the sky that is held up by thousands of long spindly arms that snatch stone from the land below.

BECOME LOCUSTS - R: Self, D: [SUM] Minutes
You and your equipment transform into a swarm of locusts. You take 1 damage from anything that does not affect an area for the duration, and you may fit through anything a locust may fit through. There are enough locusts in the swarm to lift a toddler. Optionally, choose an extra effect below per MD invested past 1:

1. Instead of transforming into locusts yourself, summon a swarm that you have complete control over. The spell lasts [DICE] hours.
2. There are enough locusts in the swarm to lift [DICE - 1] adults.
3. Instead of becoming a swarm, become one massive locust the size of a cabin.

Black Mele used his Become Locusts to create an army of monstrous insects under his command. His territory is a great fortress made of chitin, surrounded by toiling uplifted insects.

Should you do something (in)famous with a spell you use, you may add an extra custom-made option to the list of extra effects. Negotiate with the GM on this effect. Legendary wizards have many different ways to cast and amplify one spell to dangerous effect.

SYSTEM-AGNOSTIC CONSIDERATIONS AND DESIGN NOTES
(Art by Sergio Toppi)

Talking more casually, I know that's a lot and you may have the question after reading this "okay, how can I use any of this". I bolded the important stuff that makes up this magic system (I like to call it Zero Sum Magic), which you may steal piecemeal or wholesale for your games. In summary, from most critical rule (in my opinion) to the least:

1. There is only ONE of each spell in existence. One Fireball, one Charm Person, one Healing Word, etc. To own a spell is to have stolen it from someone else - nobody is born with magic.
   
   
2. You can learn ALL of a wizard's spells by consuming their skull. Anyone can do this.
   
   
3. The first time you consume a wizard's skull, you gain the ability to cast magic. If you're using GLOG, this means you gain 1 MD. If you're using some other system, this means that any class requirements that may have prevented you from using magic are removed.
   
   
4. On death, a wizard's skull casts ALL of spells stored inside it in random directions, at random targets, all within line of sight of the skull. When a wizard's skull is crushed in haste, it does the same, but it can no longer be consumed. This makes it a risky proposition to kill a wizard, the crime must be done with care.
   
   
5. Wizards can reroll reaction rolls toward commonfolk by revealing they are a wizard - positive results leave them terrified instead of friendly. (Thank you Archon for this idea)
   

Mechanically, levelless spells work best here (like ones present in Marvels & Malisons, etc), as it's disappointing to strategically kill and consume a wizard only to learn that all the spells they own you cannot cast yet because you're underlevelled. GMs, be unafraid to let your PCs play with fire!

In playtesting I've found that you should really make spells more powerful than you'd instinctively make them typically if you're an OSR GM. Think of them almost as superpowers. The example spells I list are made more powerful by adding more benefits if you gamble with more dice. Speaking of which, I highly recommend using a spell system where spells can fail somehow - it adds to the drama. Try not to make the failure "the spell fizzles", make it bombastic, make it complicate the situation - sometimes even make the mishap possibly work in their favor.

All the extra options beneath the example spells serve to broaden their use cases - as useful a spell something such as Knock is, it feels bad to be sold on the fantasy of being a powerful wizard with truly unique spells and having a spell that has very limited usage. I generally try to make most spells have some offensive use-case despite the general OSR tendencies to lean away from that. Typically the list of extra effects can be a great place to shovel in extra use-cases to really round out a spell. I recommend you model your own spells in a wizard-focused game like this after the example spells.

 I find an easy way to come up with a spell is to work backwards and come up with the wizard first, since here magic is connected to someone's being instead of a book. Additionally, if there's some sinister or strange phenomenon happening in your world, make a wizard responsible for it! It immediately gets the players imagining what they could do if they had that kind of world-altering power. A good player is a greedy player, so keep them hunting.

I can't stress enough how much you should be unafraid to let PCs play with fire. Watching them get burned makes for memorable play.

Smoking Gun (Magical Revolvers)

This is a collection of rules for firearms – revolvers, specifically – in TTRPGs. This does not aim to be a realistic portrayal – instead, an interesting one. Enjoy.

REVOLVERS
(Fernando Correra)

 First, how revolvers work mechanically. Revolvers:

• Can fire multiple shots in a single attack. Before you roll to hit, declare how many bullets you're firing and at what target(s). You get -1 to hit per target past one. If your character has multiple attacks per turn, firing a revolver spends all of them.
• Deal Xd6 damage, where X is the amount of bullets fired at the individual target.
• Reload quickly. Spend an action to reload 1d6 bullets, half if you moved this turn.
• Have range equivalent to a shortbow. In the hands of an expert, range as a longbow.
• Are all magical – every single one of them. When fired, the revolver casts the spell attached to it. The spell is cast on each taget hit. [BULLETS] is equal to the amount of bullets fired at the individual target.
• Fires strays on doubles. For each pair present, take one die away. This bullet hits an unintended target.
• Are magically catastrophic on triples. If there is a triple present, add yourself as a target of the revolver's spell, with [BULLETS] equal to 3.

As a magic item, revolvers are found where most other magic is found – in the hands of freaks and their dark abodes. For whatever reason, revolvers are a lost invention. Here are 1d6 potential reasons why:

1. Guns inspire greed, greed inspires death. The mythic underworld is full of riches; the mythic underworld is teeming with ghosts. The gunmen of the world ventured to find glory measured in silver; the gunmen of the world rot at the bottom of lightless pits.
2. The invention is not completely lost. The Gun-Pope knows their construction, the conclave shall learn upon his death. Crusaders travel the world packing heat – that of gunfire and brimstone.
3. God took the knowledge of their construction away from us. We had it coming. What he can't take away is the vestiges that still remain.
4. They used to be plentiful. After the Wizarding Wars on The Frontier, the world took a "swords to plowshares" attitude for a time. If only we lived back then.
5. We never knew how to make them in the first place. A revolver is the skull of a fae – with six sockets for six baleful eyes. Fae steal children and trick mortals to avenge their fallen bretheren.
6. Once upon a time, Methea the Knower, soon after mastering arms of fire, was torn apart by ten lions. Once upon a time, Abe de Festo was torn apart by nine lions. Once upon a time, Yulio Monteguerra was torn apart by sixteen lions. Once upon a time, Usmana Wisdom-Teeth was torn apart by twenty-two lions. Once upon a time, the brothers Salt and Petre were torn apart by six lions apiece. Once upon a time, the covert arms conglomerate SHY was torn apart by two-hundred-and-sixty-five lions.

 Bullets are rare because revolvers are rare. A bullet costs 5 sp. Per expedition, there are:

• 1d6 bullets for sale in settlements with a blacksmith.
• 2d6 bullets for sale in settlements with a gunsmith. On doubles, double the price.
• 4d6 bullets for sale in settlements with a Gun-Church. On doubles, double the price unless you are trusted by the church. On triples, the church has a blowout crisis that violently effects the community.

1D6 MAGICAL REVOLVERS
(Fernando Correra)

 

LARGE MAMA
A fat, cubic thing. It feels like a brick in your hand – hits like one, too.
Target is knocked back [BULLETS] * 10 feet and must save (subtracting [BULLETS] from the roll) or be knocked prone.

PALE HORSE
One continuous piece of ivory – save the handle, which is made of petrified wood.
If the target dies from this attack, they are raised as a ghoul under your command for [BULLETS] days. After the duration, [BULLETS]-in-6 chance they run off into the night with a will of their own. Otherwise, they disintegrate. On triples, take 2d6 damage – if you die, you become a rabid ghoul.

LITTLE VISCERATOR
More rust than gun. Somehow still works.
[BULLETS] of the target’s limbs become a lingering, bloody mist. If struck by 4+ [BULLETS], the entire target disintegrates. In [BULLETS]+1 rounds, they will reform.

FUNNY MAN
Small and snub-nosed. The trigger resembles a curled finger.
Teleport to the location of the bullet. If it struck a target, animate or inanimate, swap places with them. If you struck multiple targets, they all swap places with each other randomly. On triples, teleport to a random location within [BULLETS] miles.

PSYCHO KILLER
Ornate, curling gold. The end of the barrel resembles a smiling mouth.
[BULLETS]-in-6 chance the target goes berserk, foaming at the mouth and unable to tell friend from foe. Lasts [BULLETS] rounds. During this time the target can crawl at a dead sprint and walk on walls.

HELL'S BELLS
Small silver bells hang from the bottom of the barrel. Sounds like fifty gongs when shot.
[BULLETS]-in-6 chance the target is deafened and registers as undead [BULLETS] hours. Otherwise, just deafened for [BULLETS] rounds. 

DESIGN NOTES
(Fernando Correra)

 Talking more casually, onto design notes:

Unlike my other posts, these rules are not playtested in the slightest. I woke up, saw Loch’s GLAUGUST post (prompt was "He wields a gun"), and had an idea. However, as a GM who has included firearms in past games, I still have insights. 

I think these rules would work best in a world where the only guns in existence are magical revolvers. Adding firearms to your TTRPGs is tricky business, because all of a sudden everybody at the table begins to think their characters are gun experts. Perhaps it is because modern players can easily imagine gun violence as compared to sword violence. Having guns only be magical items makes them more similar to talking swords and the like – unique treasure that is earned, not built.

You may look at Xd6 damage and go “woah, so I can just fan the hammer for 6d6 damage at one target, that’s a lot!” That is correct – it is a gun, it kills things. I’d recommend you keep the damage this way. Doubles are a very real risk when rolling 2d6 or above, triples even more so. Emphasize risk and make it a big dramatic moment when someone empties the chamber.

If you enjoyed this, write six of your own magical revolvers!

Thank you to Gokun for the excellent sixth reason why guns are a lost invention. Thank you to Loch for inspiring me to write again. Thank you for reading.
