First of all, I wouldn't know how much a Haze Bomb like this would go for. Plus I'm probably not good at auctioning anything for the matter so I figure I'll just outright sell this thing. Good for battling enemies of the Undead family (http://wiki.spiralknights.com/Monster#Undead_Family) or Construct Family (http://wiki.spiralknights.com/Monster#Construct_Family).
Feel free to contact me in game, or send me a message if I'm not online.
My In-game name is Flaame.
