Ah, I remember wanting to do this at AX, but couldn't find you.
As I'm sure I've said before; this is the coolest idea ever.
I'll be cosplaying Serge on Friday, day 1, but I can wear it on day 2 if it's easier for you.
Here are some videos of his three special attacks;
Dash and Slash
Luminaire
Flying Arrow
If there's any other info you need at all, feel free to ask.
Keep up the amazing work!
