Some villains have weapons, and I'm particularly asking about guns/knives/etc., as part of their power sets. For example, Crossbones has Mercenary Arsenal including a Crossbow D6 and Fighting Knife D6.
I'm wondering if a hero or a villain that does not currently carry a weapon picks up a gun or other weapon, do they gain a new power set?
For example, I'm playing Beast and he picks up a Pistol D6 and starts shooting. Would he use it as a separate Power Set? In this example, could I make a dice pool including Enhances Senses to shoot someone far away or in the dark and use dice from the two Power Sets?
I realize picking up weapons isn't very common in the superhero world, but I'm just trying to understand how it works mechanically. It would seem to make sense that picking up a new weapon would make a new Power Set, but then some of the existing power sets (i.e. Black Panther) include Weapon as part of their existing Power Sets, so would this be an unfair advantage?
Finally, I'm assuming that simply picking up a weapon doesn't require creating an Asset, but then it does add a die for an extended period, so might be required?
Thanks for the clarifications.
