Fire Dust -- Sprays a stream of flame, like any flamethrower, in a cone. The flame is most potent in the middle, being a blue roaring flame instead of the orange flame near the sides.
Ice Dust -- Fires chunks of jagged ice balls in a random cone at high speeds and a high rate of fire. The ice balls are the size of a fist.
Electric Dust -- Discharges arcs of lightning like a tesla, which prioritise arcing toward metallic objects. Otherwise, discharges in the same cone.
Earth Dust -- When aimed at the ground, erects a curved, cresent wall of rock, stone and mud which acts as temporary cover. The structural integrity of the wall is not strong and will crumble in one strong hit.
Air Dust -- Ejects highly pressurised air in a cone which can knock a person over if hit directly.
Kinetic Dust -- Inserting a Kinetic Dust crystal after any of the above dust types have been loaded results in a massive increase in any projectile velocity and effective range, but horrible recoil and accuracy. Particular types to note are Electric, which do not get affected, and Earth, which makes it a rockslide instead of erecting a wall.
Gravity Dust -- The near opposite of Kinetic, inserting a Gravity crystal after any loaded Dust crystal makes the resulting output far more concentrated and accurate, albeit at a slower fire rate. Electric ignores the effect and Earth creates a solid pillar instead of a wall. The construct is much more durable.
