Just got started and am trying to keep it simple.
Goblin-melee short sword +2 (1d4/19-20)
Does that mean +2 to attack roll, damage is 1 four sided dice and what is 19-20?
shortbow +4 (1d4/x3) Is that + 4 to attack roll, damage is 1 four sided dice and what the heck is x3?
longsword +2 (1d6) why isn't there a 1d6/19-20 or 1d6/x3?
