Ironpath

Steel Rain — At the start of your hero phase,
roll a dice. On a 6+, pick an enemy unit that is
not within 1" of a terrain feature. Roll a dice for
each model in that unit (to a maximum of 10).
Inflict 1 mortal wound for each roll that is less
than the unit’s Save characteristic. A Save
characteristic of '-' counts as a 6 for the
purposes of this rule.
