By the way we have a precedent case: Piercing Talon, Enpi, Throwing Dagger, Shield Lob, Tomahawk and Lightning Shot all have the word "ranged" in their skill description.

Just Unmend and Enchanted Reprise lack that additional word.

So obviously it has something to do with the fact that these skills are both magical, while the others are physical. But why is the word only added for the physical skills? I think Rongway is in the right way here: The wording would be cumbersome o.ô;
