CPA: Skill Checks
- - - - - - - - - - - - - - - - - - -
In CPA, characters have skills which are attributes that symbolize their knowledge and ability with a certain vocation, craft, trade, field of study, or school of magic.
Skilled characters are competent.
- They are able to accomplish standard tasks commensurate with their skill level under safe and relaxed conditions, without any roll needed.
- Actions which can be done safely without a roll in unpressured time, commensurate with skill level, include:
- Operating a vehicle in casual conditions or riding a well-trained animal
- Taking an afternoon to carefully search business documents for irregularities
- Programming a normal data processing system over the course of a week, given documentation
- Sketching an illustration
Roll When It's Interesting
When the potential consequences of both success and failure are interesting, or when conditions are stressed, risky, or pressured, the GM may call for the player to roll dice to make a skill check to see roughly how well that task goes.
The basic concept of a skill roll is:
- The player says what they intend to do.
- The GM might say this calls for a roll, and explains the difficulty and stakes.
- The player rolls 2d8 + skill.
- In some cases 2d10, 1d20, or other sized dice may be used.
- After comparing the result to the difficulty, the GM improvises and explains what happens.
- The result of the roll should change the situation in an interesting way, as much as possible.
- A result of "Nothing happens" should be avoided unless absolutely necessary.
Skill Check Procedure
Declare Intent:One active player declares an intended action with an intended approach to this action. Examples:
- "I want to jump off the ground all the way to the moon."
- "Officer Jones wants to use her laser cutter to try to open the hatch on the crashed vehicle."
- "I want to try to intimidate the club's security guard with my strength."
- "Jim wants to try to get the giant squid to calm down so it doesn't bite him."
Clarify Approach: The GM may ask the player to add more details of exactly how they are approaching the action, in order to help contextualize the potential risks and rewards.
- "Are you just trying to jump normally or with telekinesis?
- "How are you intimidiating the guard exactly? Bending or breaking some object, threatening him, shoving him, shouting at him, or something else?
- "Are you trying to carefully cut open the door so that it can be repaired later, or just burn through as fast as possible?"
- "Are you trying to calm the squid by offering it food, or by hiding yourself or pretending to be a rock, or something else?"
Set Stakes and Difficulty:The GM improvises and declares whether or not a roll is needed for this intended attempt, what that roll can be, what the player is risking, and what the target number is. Examples:
- "No, you cannot jump to the moon without some ultra-tech ion boots, or max-level telekinesis, or something similar."
- "Sure, you can roll Brawl or Athletics to try to intimidate the guard by crushing his hand. Difficulty...14. You're risking drawing a lot of negative attention if this doesn't work smoothly."
- "Since you've worked with these tools in your background, the water is shallow and calm, and you're not under pressure right now, no need to roll. You easily and cleanly cut off the hatch with your welding tools, though it drains the battery 50%."
- "You are 2000 meters under an ocean of liquid methane, with a damaged diving suit, two levels of exhaustion, and you want to try to offer a snack to this giant monster? Roll Animals with disadvantage, TN 20, and it's likely you'll be bitten on a failure."
Helping: The game already assumes that everyone who wants to help the active player does. If you want to aid more directly, look into the leadership skill and the athletics focus.
Roll: The acting player rolls two dice, usually 2d8, and adds their relevant Skill Level and any other modifiers.
- If the player does not posess the skill at least level 1, then a -2 penalty modifier is applied to the roll.
- Some features may modify a skill check roll in a way other than simply adding to the result.
- Some features may allow you to roll a skill check with a different die set. If they do, you can either roll normally (2d8+skill) or the specified dice + skill. These do not stack.
- If a feature says to add an advantage die, then you roll 3 dice and take the highest 2. This can stack, i.e., rolling 4 and taking the highest 2, or net with disadvantage.
- If a feature says you have a disadvantage die, then you roll 3 dice and take the lowest 2. This can stack, i.e., rolling 4 and taking the lowest 2, or net with advantage.
- Common sources of these features include focus skills, talents, exhaustion, bad weather, particularly effective approaches, divine disfavor, cursed ground, etc.
Result:Based on the result, and the context, the GM improvises and explains the result along these degrees of success: The following are the general categories of results on skill checks:
|Critical Success||6+ units higher than TN, or, max #s on both dice.||The player achieves their goal in a heroic way--that is, with a major bonus. If not possible, then they achieve far more than the average person could.|
|Success||Result is equal to or +1-5 points higher than TN||The player generally achieves their intent as is reasonable.|
|Cost||Result is 1-3 points less than TN:||The player either only partially achieves the intent, or may achieve it but at a cost. The GM should often give them a choice of costs or choice of partial successes.|
|Failure||Result is 4- units lower than TN||The situation changes and this approach becomes impossible.|
|Critical Failure||Critical Failure! 6 units lower than target, or two 1's on your dice||Regardless of the sum total, this attempt ends in disaster, dramatically changing the situation.|
- "You rolled a 13 athletics...Ok, you're able to jump, grab the edge of the roof, and climb up."
- "Wow! You rolled a crit! The guy yelps in pain and jumps back, dropping his ID card on the floor at your feet. The other patrons laugh at him--apparently they like your style."
- "It's not easy to use a welding torch underwater during a hurricane. You cut halfway through the door over 30 minutes but your battery dies. You guys will have to try something else to get this door open."
- "With merely a 10 on your animals roll, this isn't looking good. The squid is rapidly approaching, and you have a terrible headache. You think the squid might be distracted if you threw a signal flare, but it might cause an implosion if you do. Do you want to try it, or simply run away?"
7. But remember, you are a mere mortal among perilous cosmic forces.
- Despite all this, remember that circumstances are unpredictable and unknowable. Special circumstances could cause changes in difficulty, problems even on a high success, or simply rolling a skill might not be an option when dealing with psychic storms, angry gods, or bleeding gashes in space-time.
- A range of difficulties exist to support a world where players can go from ordinary human to minor heroic skills, while still maintaining numeric space for terror.
- The difficulties for a given mission's main tasks should be chosen generally such that there is a good chance for some success and many interesting costs and failures.
- For this reason, when unsure, lean high(14+) on your set difficulties as you can always allow some minor progress at a cost or choice of advances/costs when a low result is rolled.
- The 10-14 range is generally challenging only for people who are not focused in a certain skill.
- The 14-16 range of difficulty is a good region for challenging players who are focused in that skill.
- Difficulties 16+ are risky even for advanced and focused players.
|Target Number (TN):||Description|
|Automatic||No roll is required for skilled players to perform basic tasks: Driving down a safe street, finding public service information, asking for extra pillows at a hotel.|
|10||Basic risks: distracting a lazy policeman, fighting a goblin or rabid dog, climbing an icy snowbank, tying up a prisoner securely.||12||Professional assignments: Negotiating a discount on a purchase, repairing a damaged engine, fighting off a bandit, descending a short cliff.|
|14||Advanced projects: Diving in a shallow sea cave, embedding a gem into armor, negotiating a mining contract, fighting an ogre or security robot.|
|16||Expert Feats: daring vehicle jumps, crafting a sword from demon bones, out-shooting an assault robot, leaping across rooftops.|
|18||Expert Ambitions: Fighting a dragon, tricking a crime lord to confess, sneaking into a palace, deciphering an alien computer system.|
|20||Cosmic Peril: Dealing with extradimensional horrors, magically turning back time, navigating a hyperspace storm, calming an angry god.|
|Impossible||Don't roll to attempt impossible tasks. Examples include magic for which you are unskilled, or actions for which you cannot meet the target number; these are not possible.|
- Casting is always dangerous and rolls cannot be skipped.
- Level 4, 5, and 6 spells are increasingly exponentially dangerous. High level spells are fair game for punishing costs or unintended consequences even on a success roll.
- This is because magic originates in other dimensions that mortals can never fully understand.
- Wearing medium or heavy armor is disadvantageous to spellcasting.
- When you have a cost or fail in casting a spell, the situation is changed, even for seemingly mild magic.
- Costs might make you unable to try the spell for an hour, drain your energy or health, be less effective, make future spells more difficult, or alert enemies magically.
- On a failure, the spell may turn against you, cause your wand to explode, become useless for a day, cause you to bleed profusely, or far worse.
- Countless different complications are possible, and the play-group should try to always keep it unique and interesting, this keeps magic feeling mysterious. Check the table below for more ideas.
- To cast, a caster must spend Energy Points (EP) commensurate to the spell's level regardless of outcome.
- Usually, maximum Energy Points = 5 + your total arcane skill levels. For example, if you have level 3 in Teleportation and level 4 in Necromancy, you would have 5 + 3 + 4 = 12 Energy Points maximum.
- All casters can regenerate Energy Points at a base rate of 1 per 4 hours of meditation or rest. Casters who have levels in the Meditation skill can regenerate Energy Points equal to their skill level in Meditation per hour of meditation or rest.
- Particularly successful or unsuccessful castings may provide Energy Point discounts or surcharges.
- If you have no EP, then you can spend your HP as EP, but at a 4x premium -- for example, casting a level 2 spell would cost 8 HP.
- There may be other ways to refresh Energy Points as well, notably via mana potions, or making pacts with powerful spirits. Explore and discover.
- Spells can only be attempted by people with arcane skills.
- Only those with "the gift" and years of formal arcane training may attempt spells.
- A small minority of people posess "the gift" and may be aware or unaware of it. They can be identified with use of the Metaphysics skill.
- People who have "the gift" but are not formally trained risk permanent brain damage or violent extradimensional posession by attempting to cast.
- People with one or more Arcane Focus Skills are considered to have both the gift AND years of formal training. They mitigate dangerous casting outcomes to a more reasonable level (Specifically, when casting low-level spells.).
- Casting magic requires a visible sign.
- This could be pointing or hand gestures, brandishing of a staff or wand, a flash of glowing light from the eyes, or some other visually obvious sign.
- By default, it is an obvious 1-handed gesture, arm held straight out and palm extended towards the target area. This can't be done while the caster is restrained.
- Some ongoing spells require maintenance of concentration.
- The typical caster has a maximum concentration of 1.
- If subjected to any distraction during concentration, a binary Meditation check must be rolled immediately vs. the enemy's attack TN.
- If the check is failed by any amount, all active concentrations are dropped immediately.
- The caster must be conscious to maintain concentration.
- Concentration may also be occupied by non-magical activities such as computer programming, vehicle piloting, intense athletics, etc
- You can end one or more concentrations at any time with no action cost.
- All spells can be cast as rituals, but some spells have a minimum ritual requirement.
- Ritual means that the casting involves a significant amount of time as well as some combination of physical movements and spoken words.
- Rituals require a spacious, clean, quiet and safe workspace. If disrupted, a ritual will automatically fail in most cases.
- The success chance of all spells, shown below, may sometimes be improved with direct performance of art or music, sacrifice of high value, promises to or favors from spirits, the aid of other casters, and other factors.
|Arcane Spell Levels||Energy Point Cost||Casting Target Number||Chance for success with +X||Chance for success with +8|
|1||1||10||+1: 56%||+8: 100%|
|2||2||12||+2: 44%||+8: 95%|
|3||3||14||+3: 33%||+8: 84%|
|4||4||16||+4: 23%||+8: 67%|
|5||5||18||+5: 16%||+8: 44%|
|6||6||20||+6: 9%||+8: 23%|
1d20 Suggested Spell Costs and Miscasts

|4||The caster's HP is harmed by the casting.||14||The caster's exhaustion level is increased.|
|5||The spell has an undesired effect, different from the intention.||15||The spell has the opposite of the intended effect.|
|6||The local environment is desecrated by unbound magic.||16||A portal to a dimension thematically related to the spell is briefly torn open.|
|7||Enemies are magically alerted to your presence.||17||An invisible demon enters the caster via the spell and causes bad things to happen around them until detected and exorcised.|
|8||The spell gains a mind of its own.||18||The spell causes this roof or building to collapse, causing damage and blocking progress.|
|9||The spell mutates someone, temporariliy or permanently.||19||The spell creates a clone or opposite twin of an ally or enemy.|
|10||The spell invites a demon, horror or extradimensional infestation to this area.||20||The spell empowers an enemy or weakens an ally.|
Like the rest of the system, hacking in CPA is handled in a simple and low-power way, with improvisation used for finer details.To hack a system, you must do the following:
Find a local sub-network terminal.
Typically, the following systems are divided into separate networks, which will need to be hacked separately and locally:
- Security // Maintenance // Engineering // Robots // Operations // Personnel // Life Support // Central AI // Database etc.
- You must find a local terminal, ON THE SITE of your goal; in the future, electronic security protocols are highly developed and easily shut down most cross-internet cracking attempts.
Log in.This usually requires credentials, an access card, or a 20-minute crack attempt with a hard-wired or hot-wired connection vs the system TN.
- As an example, to open a certain locked auto-door, you could steal an officer access card, hack the central security processor, steal a worker access card and reprogram it, or hot-wire your rig to the door lock with Crafting and try to crack that.
- Some systems may have layers of access. For example, you may have the dictator's control room passcode but there may be a separate override key-code for the automated killbots or missile silo launch codes.
- If your attempt fails, you may get feedback damage, your equipment fried, your data lost, raise the alarm level, hard-lock the terminal, raise all TNs for this area, or trigger traps.
Use normal system functions. With unfettered access to a system, you can perform normal functions at this point, with a TN of 0-20 based on the simplicity of the interface.
- For example, if you have full access to the maintenance system, and it is simple to use, you could shut off the lights or redirect ventilation in the officers' room with one click.
- But if you wanted to reprogam the replicators to make bullets instead of candy bars, that would require a hack.
- Some actions with unlocked computers may use other skills: social skills for chats, investigate for obscure data, crafting for CAD/CAM and fabricators, etc
- Adventurers are often breaking into secure areas; for this reason the central security computer is often a hacker's main target. Once down, the enemy cannot confidently rely on patrol bots but may still have a few emergency backup auto-defense systems that are self-powered.
If you intend to destroy or alter the system:Prepare to make a Computers check. Declare the intent of your hack, spend 60 minutes of in-game time to work on it, and roll Computers skill vs the system TN.
- Destroying or altering a system might include actions such as:
- Completely shutting down a self-checking security network
- Corrupting or un-braking an AI persona core
- Reprogramming an automated factory's work order flow system from one faction to another
- Inserting a virus that fries all data in an office building
- System TNs vary from 10-20 from obsolete models to corporate security to self-checking divine AIs.
- Modifiers can be applied to your roll:
- Trying to complete the job faster increases TN significantly.
- Earthquakes, bombardment, or other distractions increase TN significantly and may prompt meditation checks to stay focused.
- Trying to hack via a remote controlled drone increases TN due to packet loss and interference.
- Using powerful virus software can reduce your TN but is generally a one-time consumable use as adaptive systems learn from it.
- Similar to other skills, the effect or magnitude of your success or failure will determine the consequences.
- High successes allow a greater effect, a longer safe time, etc.
- Near misses allow an extremely short time window for the hack or allow it but raise the alarm level (i.e., from yellow to orange alert).
- Failures may give you feedback damage, fry your equipment, raise a high alert, lock out your terminal, raise all TNs for the area, or trigger more traps to activate.
- Destroying or altering a system might include actions such as:
- The three main crafting actions are to build, repair, or modify items. In all cases, your skill check result will affect how fast and/or how well you produce results.
- Similar to spells and hacking, the greater your ambition (higher TN), the greater risk you have on a subpar roll. Near-miss rolls may give you a choice of costs or a success with a complication.
- If you really want to ensure that something is properly crafted, ask the GM if you can take extra time and/or ingredients to ensure a success without a roll that is commensurate to your skill level.
- Keep in mind that both crafting and brewing require the necessary ingredients, tools, and workspace.
- Electricity, engines and gun technology is not learned via this skill, but is learned via in-game events, if at all. The GM may ban those things from a setting, but all settings should include drinkable/injectable potions and throwable bombs. For example:
- Fantasy settings generally do not allow guns, electric power plants or combustion engines to preserve a theme and feel, but may include alchemical explosives.
- Modern or Hard sci-fi settings allow those things but do not allow faster-than-light (FTL) engines, to preserve a realistic technology feel, while soft sci-fi usually allows FTL.
- Settings that bridge genres (sci-fantasy, or hard sci-fi into soft sci-fi) will allow players to craft those things only once they acquire blueprints for them.
- Item Modifications: Each piece of gear can have a maximum of 1 modification upon it, which gives +1 to 1 statistic. For example, you can inset a demon skull into a sword to give it +1 accuracy or +1 life steal per hit. Or, you could inset a ruby to give it fire damage.
- The ultimate success of all crafting attempts always depends upon four factors:
- Quality of Materials
- Quality of Workspace and Tools
- Amount of Time Spent
- Skill Level
|Skill Level||Crafting Items||Science Items||TN for basic success||Typical base time for basic success|
|1||Basic bows, leather or kevlar armor, rope tying skills, knives, arrows, spears, simple tools||Anti-toxin drugs, disinfectant, soap, distillation of flammable oil or alcohol||10||1 hour|
|2||Crossbows, bolts or pistol bullets, throwing knives/axes, chain or ceramic insert armor, simple electronics such as timers and alarms, dinghies, simple weapon +1 damage or accuracy modifications||1d4 healing and mana drugs, small acid or fire bombs, smoke and flash bombs||12||3 hours|
|3||Large-clip crossbows, ballistas, handguns, rifle and sniper bullets, extraordinary swords, unpowered carts, small sailboats, weapon effect modifications||1d8 healing and mana drugs, medium acid or fire or freeze bombs, small batteries, cures for paralysis, blindness, disease, etc||14||6 hours|
|4||Long guns, heavy weapon ammunition, elemental weapon modifications, small powered ground vehicles, hang-gliders||3d4 healing and mana drugs, large acid/fire/freeze/EMP bombs, power cells, minor temporary mutagens||16||12 hours|
|5||Magical runic swords and bows, heavy cannons, all possible weapon modifications (GM's discretion), construct all ground vehicles, air/water/space vehicle repairs||4d4 healing and mana drugs, large aerial bombs of any type with city-block explosions, major temporary mutagens||18||1 week|
|6||Legendary weapons, special ammunition, construct any vehicle, experimental magi-tech||3d6 healing and mana drugs, weapons of mass destruction (WMDs), permanent mutagens, experimental mad science||20||2 months, but varies|
