At the start of the Magic phase, after power and dispel dice have been generated, but before spells are cast, the sorcerous portal casts a magic missile with a 12" range that causes D6 Strength 4 Hits. The spell does not need line of sight, always targets the closest unit (regardless of range, if the unit is in combat and so on), is automatically cast and cannot be dispelled. If the spell has a choice of casting values, it is assumed to be cast at the lower value.
