Ammunition Sizes

For the sake of simplicity, ammunition is shared amongst weapons that deal the same damage type. For instance, all blasters that deal kinetic damage utilize slug cartridges, while all blasters that deal energy, ion, or other elemental damage types utilize power cells. If you dislike that an assault cannon and a blaster pistol utilize the same ammunition, consider the following variant rule.

Damage Dice Ammo Size

Slug cartridges and power cells are each broken down into five size categories, from Tiny to Huge. These new sized ammunitions only fit in weapons that utilize certain damage values, as shown in the below table.

For those weapons with alternative damage types, you'll want to treat their damage as one step higher. Ion damage should be two steps higher or twice the weapon's damage, whichever is lower.

For instance, a blaster which deals 1d8 energy damage would use Medium power cells, while a blaster that deals 1d4 kinetic damage would use Tiny slug cartridges. A blaster that deals 1d4 fire damage, however, would use Small power cells (since we treat that damage as one step higher), as would a blaster that deals 1d3 ion damage (since we treat that damage as two steps higher).

Ammo Size Values and Weights

Additionally, the value and weight of these sized munitions would scale, as shown in the table below.

Powered by Power Cells

Items that are powered by power cells, such as jetpacks or glowrods, would utilize Medium power cells.
