Magical weapons give off a faint glow when used (the color is up to the GM’s fancy). Normally, magic weapons have a bonus to hit, such as a +1, +2, +3, or more. They could have other powers in addition, such as a damage bonus. Some magic weapons go as far as requiring the wielder be of a certain alignment or suffer some damage when touching them. Certain creatures can only be hit by magic weapons.
See the Treasure section later for some examples of magic weapons.
