If you're correct, and I'm not certain you are or not, this creates an odd occurance. A dagger is a light weapon, therefore it would work with the Swashbucklers insightful strike whether or not it was thrown. My interpretation, since the insightful strike ability doesn't state that it only applies to melee weapons. Yet, a shuriken wouldn't work with insightful strike because it is a ranged weapon. My question is, why not? The definition for a light weapon does not specify that the weapon must be a melee weapon. Aside from the weapon tables that break down weapons by type, what evidence is there that a ranged weapon can't also be a light weapon?
