A whip would technically count as a weapon, yes. And unfortunately, whips are kind of tricky in that there isn't really a way to un-weaponize them (the way that you could blunt the edge of a knife, for example), so it'd be difficult to give him one that would still comport with our weapons rules.

However, please feel free to ask us all the questions you like - we're happy to work with you in finding a workable idea for his drop!
