know how to change dark wizard to assassin coat??

I would love to be able to do this on the client side only pm me if you know how thanks in advance....

dark wizard is a garment , "assassin coat" is a flag

you may replace garment with garment or garment with armor/coat but not with a flag
if you really like the flag then search for some flag you use and change it for assassin flag which i don't think you will have any if you are not assassin

forget about it buddy , else go use comon and send to yourself the flag packet and see if it's going to work out as visual effect for your client
