Storm Banner

One use only
The banner can be activated at the beginning of any player's turn. No flying movement is allowed across the entire battlefield and missile fire is -2 to hit. All non magical missile attacks that don't use BS to hit their target need to roll a 1+ on a 1D6 before they can fire. Roll a 1D6 at the beginning of each of the following player's turns - the effects of the banner will end on the roll of a 1 or 2.
