If a character already has a weapons skill with a specialism (for example, Ranged Weapons- Hand Phaser) and then takes the Weapons Mastery Edge and applies it to Hand Phaser, does he get a modifier of +2+3= +5 (+2 for the specialism and +3 for the Edge) or simply +3? Does the Edge increases the usual specialism bonus from +2 to +3 or is it +3 in addition to the usual +2 specialism bonus??
