The galaxy is a dangerous place. Most people have access to some kind of weapon, and those who travel the space lanes often carry a blaster on top of that.
A weapon's legality depends on where you are. No one would look twice at a character wearing a blaster at their side on Mos Espa or Nar Shaddaa. The same character would do well to conceal it while visiting the gleaming metropolis of Coruscant.
Used in close combat, Melee Weapons usually deal Bludgeoning, Slashing, or Piercing damage—depending on the weapon's design.
Some combine powered components to augment the user's own strength.
Many types of Melee Weapons are widely available and have few governmental or legal restrictions. Civilians, law enforcement agents, and military personnel alike carry these items.
A character's Strength modifier is always applied to a Melee Weapon's attack roll and damage roll.
Ranged:
At any given time, hundreds of manufacturers are creating and marketing a wide array of ranged weapons. These weapons run the gamut from small, concealable handheld weapons to Tripod-mounted cannons that require a small crew to operate.
