Mechanically, a material in Starfall Galaxy is a modifier layer you apply to an item’s base statistics—armor, weapons, shields, drones, vehicles, and structures—to change durability, weight, cost, and sometimes traits or resistances. A standard rules workflow looks like this:

• Choose a base item (e.g., level 5 small arm, level 4 light armor, bulkhead door).

• Choose a material template .

• Apply the material’s modifiers to Hardness, HP, Bulk, traits, and cost, keeping numbers within SF2e item math for the item’s level.
