"The character can attack with this weapon as his Reaction."
This is what the description for the ballistic mechadendrite says in my book. No more, no less. All the other mechadendrites have it stated in their rules that you can use them to make Standard Attacks as a half action (vastly limiting their use, but at least limiting it clearly). Does anyone know if the intention behind the much shorter description of the ballistic mechadendrite was to allow the ballistic mechadendrite to be used as a regular weapon as well, or if it was to allow to be used *only* as a reaction?
