Firearm Malfunctions

Simple Firearm Malfunctions
d10 Malfunction Description
1 Stovepipe The casing does not clear the action before reload, and is stuck. One action to clear, no permanent damage to the firearm.
2 Fail to Feed A cartridge becomes jammed as it’s loaded into the breech. 1 action to clear, no permanent damage to the firearm.
3 Dud The ammunition’s primer fails to ignite. 1 action to clear, no permanent damage to the firearm, loss of the cartridge as it must be ejected. No permanent damage to the firearm.
4 Hang Fire The chemical reaction firing the projectile is delayed due to manufacturing defect. A -5 to hit penalty is applied to the attack. No permanent damage to the firearm.
5 Squib Load, Minor The chemical reaction during firing is insufficiently powerful to carry the projectile. The bullet clears the muzzle, but the attack fails. No permanent damage to the firearm.
6 Slam Fire, Minor The projectile is fired prematurely as it is being loaded into the chamber. A -5 to hit penalty is applied to the attack. No permanent damage to the firearm.
7 Out-Of-Battery, Minor The firearms action was not fully reset between firings. Requires 1 action to correct. No permanent damage to the firearm.
8 Hammer Follow, Minor The hammer follows the firing pin and bolt into the battery as the action closes. This causes an unintentional discharge similar to a slam fire. A -5 to hit penalty is applied to the attack. No permanent damage to the firearm.
9 Fail to Fire The weapons firing pin failed to strike the primer. One action to clear, no permanent damage to the firearm. Loss of the cartridge as it must be ejected.
10 Fail to Eject, Minor The spent cartridge fails to be ejected from the breech after firing. One action to correct.

Dangerous Firearm Malfunctions
d8 Malfunction Description
1 Squib Load, Major The chemical reaction during firing is insufficiently powerful to carry the projectile, and it becomes lodged in the barrel. The firearm should not be fired until 10 minutes are spent repairing it. Until then, consider the weapon’s Wear Number to be at 100%. It might be difficult for a user to notice a squib load, so at the DMs discretion a perception check can be called. In the case of automatic weapons, the DM may decide the weapon is firing too quickly to notice at all.
2 Fail to Eject, Major The spent cartridge from the previous shot fails to eject, and a new round is picked up from the magazine and jams into the spent cartridge. Requires 5 minutes to clear. The firearm cannot be operated until it is repaired.
3 Case Head Separation The casing for the cartridge fails, causing it to break into several pieces inside the breech. Will require about 30 minutes to repair. Firearm cannot be fired until then. If an attempt is made to fire the weapon, it jams, requiring ten minutes to repair. It might be difficult for a user to notice a case head separation, so at the DMs discretion a perception check can be called. In the case of automatic weapons, the DM may decide the weapon is firing too quickly to notice at all.
4 Hammer Follow, Major The hammer follows the firing pin and bolt into the battery as the action closes. This causes an unintentional discharge similar to a slam fire. The weapon’s magazine is permanently damaged. The premature firing causes severe damage to the firearm, requiring a gunsmith 1 day and ⅓ the firearm’s cost to repair. Until repaired, consider the firearm to be at 95% wear.
5 Major Malfunction Some part of the action mechanically fails. For example, the slide stop breaks, a retainer fails, etc. The result is relatively harmless to the user, but the firearm is considered destroyed. A gunsmith can fix it over the course of 14 days and ⅔ the firearm’s cost.
6 Mechanical Failure The weapon’s firing pin, spring, or some other component fails. The weapon will not fire. Consider it destroyed until a gunsmith can repair it over the course of 5 days and ⅔ the firearm’s cost.
7 Magazine Retainer The magazine won’t lock into the weapon. The weapon will still fire, but must be manually fed cartridges one at a time. Consider this condition permanent until a gunsmith can repair the weapon over the course of 3 days and ⅓ the cost of the firearm. If the weapon does not use a magazine, ignore this result.
8 Magazine Failure The weapon’s magazine is ruined. Consider it destroyed. The weapon requires 1 minute to fix the jam from the broken magazine. All ammo in the broken magazine may be removed with a reasonable amount of time to do so.If the weapon does not use a magazine, roll again.
Catastrophic Firearm Failure
d4 Malfunction Description
1 Catastrophic Failure The weapon’s action is blown apart into several pieces. The firearm is completely destroyed, and the user takes damage from the weapon as if it were fired at them from close range. At the DMs discretion, the failure could render the user blind.
2 Barrel Shear Either a partial obstruction or faulty cartridge causes the barrel to flex when fired, causing it to break or crack. The flex also causes kinetic energy to transfer back to the action, ruining it. Consider the weapon completely destroyed.
3 Severe Malfunction Some part of the action mechanically fails. For example, the slide stop breaks, a retainer fails, etc. The firearm is considered destroyed, and it causes some harm to the user. The user takes damage equal to the weapon’s damage roll at medium range.
4 Magazine Denotation A slam fire ignites a round in the magazine, causing them all to explode. User takes 1d4 damage for every cartridge still in the magazine. The weapon is completely destroyed. If the weapon does not use a magazine, roll again.

Vehicle Malfunctions

Most of these vehicle malfunctions apply to vehicles with internal combustion engines. Vehicles that do not have engines (bikes, skateboards, etc.) should ignore any result that does not apply to them. This leaves results that apply mostly to the wheels/tires.

Simple Vehicle Malfunctions
d10 Malfunction Description
1 Flat Tire A puncture in the tire is preventing the tire from holding air. Continuing to drive on it reduced handling, fuel economy, and will damage the rims in short order. Most vehicles come equipped with a spare. A can of fix-a-flat can provide a temporary solution as well. If the vehicle does not have a tires, ignore this result.
2 Headlight Out One of the headlights has stopped working. If you get this result twice, neither of the headlights will function. Can be repairs without any mechanic proficiency in about 15 minutes. If the vehicle does not have a headlights, ignore this result.
3 Dead Battery The follow will occur the next time the vehicle is started: The battery is drained due to something drawing power from it for an extended period. It will be fine if you can get a jump start.
4 Engine Flooded Multiple attempts to start the car have caused an overabundance of fuel to enter the combustion chamber. In 5 minutes, the gasoline will begin to evaporate and the car will start.
5 Clogged Carb/Injection The following occurs the next time the vehicle is started: The car won’t start. Deposits are forming in the carburetor or fuel injection. Without maintenance this can prevent a car from starting. In the meantime, you can get the vehicle started by using starting fluid or a small amount of gasoline in the air intake.
6 Leaky Radiator Coolant is slowly leaking from the radiator. It can be repaired by a mechanic, but a bottle of StopLeak provides a temporary solution.
7 Oil Leak Oil is leaking from the car. You will need to stop and fill the car up with oil every 100 miles until you can get it repaired.
8 Low Coolant The coolant level is low due to a slow leak. You will need to fill it up every 100 miles until you can get it repaired.
9 Weak Battery The battery isn’t holding a full charge. It will now take about a minute to get it started whenever the engine turns off, until you can get it repaired.
10 Gas Leak There is a pinhole somewhere in the fuel system. Fuel economy becomes 25% worse, and it’s a potential fire hazard. See Catastrophic Explosion.
Dangerous Vehicle Malfunctions
d10 Malfunction Description
1 Dead Alternator The battery drains very fast due to a faulty alternator. It will need to be repaired before the vehicle will function. This requires an appropriate mechanic proficiency to repair.
2 Water Pump The water pump has broken. The car will overheat if you drive it too long. This requires an appropriate mechanic proficiency to repair.
3 Thermostat The thermostat has broken, resulting in the vehicle not being able to regulate the engine coolant. If you do not repair this, the engine will overheat if you drive it too long. This requires an appropriate mechanic proficiency to repair.
4 Tie Rod End A tie rod is worn, resulting in significant wobble in the wheels. If it’s not repaired, a catastrophic problem could occur - see The Wheels Come Off. This requires an appropriate mechanic proficiency to repair.
5 Brakes The brakes need work. The pads can be considered routine maintenance, so this problem is more with the rotors and calipers. This requires an appropriate mechanic proficiency to repair. Failure to repair this can lead to a catastrophic failure. See No Brakes. If the vehicle does not have a suspension, ignore this result.
6 Fouled Battery The battery in the vehicle is complete dead and will not hold a charge. You will need to replace it with a new one. This requires an appropriate mechanic proficiency to repair.
7 Cracked Block The engine block has a hairline fracture in it. The car is doomed, but you can at least continue driving it until it breaks down completely. From now on, this this vehicle can no longer be repaired.
8 Tricky Transmission The transmission seems to be going out. It shifts hard and sometimes won’t kick into gear. It’s beyond repair at this point, but you can at least continue driving until it breaks down completely. See Transmission Failure. From now on, this vehicle can no longer be repaired.
9 Serpentine Belt Broke The serpentine belt broke. Same result as Dead Alternator, but does not require mechanic proficiency to repair.
10 Dead Spark Plugs The engine cannot fire until they are replaced. Does not require mechanic proficiency to repair.
