Warhammer uses two special dice: the artillery dice (marked 2, 4, 6, 8, 10 and Misfire) and a scatter dice (marked with arrows and Hit! symbols). These dice are mostly used to represent the effects of various war machines, such as cannon and stone throwers. Note that, except where clearly specified, the artillery and scatter dice cannot be re-rolled. We've not talked about re-rolls yet, but we will do shortly.
