A friend of mine gave me a big box full of hundreds of HeroClix figurines back in high school (they were his step-dad's, who didn't want them anymore).

Been coasting off those figurines for every D&D session I've ever been a part of. They don't quite fit in a 5x5 square on standard D&D maps but they get the job done.

Seems Just fine for a Warforged Gunslinger.

As for the question about whether or not a warforged gunslinger is the right character for a D&D campaign is an entirely different question.

Is this a depiction of the battle at Amon Hen?
