  1. The SRD only gives a means to determine costs and weights of weapons for Large and Small versions based on the Medium weapons. Any other supplied values are the author's best determination.

The Gatling gun was invented by Richard J. Gatling, who wished to create a weapon that could supersede an entire squad, so that less soldiers would be necessary in an army and their exposure to danger would be reduced.

A Gatling gun is a siege engine, not a weapon. A Gatling gun must be mounted on an artillery cart or a stationary support to be fired. The device and cart together are one size category larger than the intended operator, for whom the sizes are listed. A Gatling gun is usually pulled around on its cart rather than carried, but can be carried (but not fired) in a pinch. A Gatling gun is fired by turning its crank. A Gatling gun is listed as a simple weapon because all that is required to use it is to aim and turn the crank. The operator must know this to use it.

A Gatling gun can make a number of attacks per round equal to 2 + its operator's Strength score as a full-round action, or half its operator's strength score as a standard action. Each sequential attack takes a cumulative -1 penalty on its attack roll. All attacks must be made within a 90-degree cone, and the gun may turn in only one direction while firing. (So the gun could attack target A a number of times, then attack target B a number of times, but could not then turn to hit target A again.) Firing a Gatling gun always provokes an Attack of Opportunity.

A Gatling gun's cartridges are waterproof and self-contained, so it can fire when wet. It may be fired underwater, but the number of attacks that may be made per round is halved, the penalty for each subsequent attack increases to -2, and its range increment decreases to 5 feet. A Gatling gun can be used in the absence of air.

Reloading a Gatling gun is a move-equivalent action. A Gatling gun is reloaded either by pouring ammunition into a hopper attached to the feed, which does not interfere with firing during that round, or by removing whatever is attached to the feed and attaching a magazine, which prevents the gun from firing during that round. A hopper or magazine without cartridges is cheap: only 1 sp. Each cartridge costs 1 gp. A magazine can hold 120 cartridges, while a hopper can hold 30.

A Gatling gun's bullets do piercing damage. They are usually made of lead (hardness 7).

A Gatling gun's magical enhancements cost 10 times what they would normally cost.

After 1 round of firing black-powder (the default) rounds, a cloud of thick smoke is visible at the gun's location, making it very obvious (DC 0 Spot check, before applying distance modification) and makes ranged attacks going through that square take a -1 circumstance penalty. This smoke dissipates after 1d6 rounds in light wind, after 1d4 rounds in moderate wind, or after 1 round in strong wind or stronger.

Several material changes may be made to the composition of the cartridge or the gunpowder used. Changes to powder may stack with changes to cartridge material.

Table: Cartridge Material Enhancements[edit]

Modification Change in cost Change in Craft DC Special
Smokeless powder +5 sp +2 Prevents smoke, range increment +20 ft.
Iron cartridge -5 sp -1 Become useless in water or if dropped
Potassium paper cartridge +5 sp +1 Doesn't leave empty cartridges

Bullet prices are given for single cartridges, rather than lots of 10. Cartridges are bought one at a time. Firing a bullet from a gun made of a material with lower hardness than the bullet will cause the bullet's damage to also be dealt to the gun, regardless of whether the bullet hits.
