Liquid Projector
Defaults: DX-4.
This is the ability to use a weapon that projects a stream of liquid or gas. Roll against Liquid Projector skill to hit your target.
Make an IQ-based Liquid Projector roll to take immediate action (e.g., patch a leak), should your weapon fail. You must specialize by weapon type:
Flamethrower: Any weapon that projects burning liquid or gas. (This does not include plasma weapons, which are often called "flamers"; use Beam Weapons skill for those.)
Sprayer: Any weapon that emits a gas or atomized liquid (nerve gas, sleeping gas, etc.), including an ordinary spray can used as an improvised weapon.
Squirt Gun: Any weapon that fires a low-pressure stream of liquid at the rate of one squirt per pull of the trigger.
Water Cannon: Any weapon that fires a continuous jet of high-pressure liquid, usually but not always water, with the intent of causing knockback. These specialties default to one another at -4. The weapons covered by each specialty vary by TL; e.g., Liquid Projector (Flamethrower) covers fire-siphons loaded with Greek fire at TL4, while at TL6, it covers backpack tanks that project thickened fuel.
Modifiers: All applicable ranged combat modifiers; -2 for heavy weapons when you are used to portable weapons (e.g., a flamethrower mounted on a tank when you are used to a backpack model), or for an unfamiliar weapon of a known type; -4 or more for a weapon in bad repair.
