All Dex Weapons are now able to use abilities that would normally be usable for that archetype of weapon, including Dex Magic Weapons.
This does not provide the ability to create extra magic abilities beyond what the Dex weapon has, but allows the Dex user to also use non-magical Abilities that would be used with normal weapons of the same type; i.e. 2 Bows, 1 magical and 1 non-magical.
Any Dex Magic Weapon such as Bows or Crossbows that does not depict a string instead creates a string of magoi that can launch the arrow from the regular ability.
You may share basic ammunition between your normal Ancient Weapon and your Dex Magic Weapon if they are of the same type, but you do not get extra ammunition for it.
