A weapon feature describe any special rules that apply only to that particular weapon. For example, some features reduce or increase your character’s statistics, while others give them special ways to deal damage. A weapon’s features only apply to that weapon; you can’t apply its features to a different weapon. Your character can only benefit from a weapon’s features while the weapon is equipped. If you put a weapon into your inventory, lose it, or get rid of it, your character no longer gains the benefits of that feature.
