Celestial Blades

Celestial Blades is a spell that has a casting value
of 5 and a range of 12" if the caster is a Knight
or 18" if the caster is a Lord or Draconith.

Eternals unit wholly within range and visible to
the caster. Add 1 to wound rolls for attacks made
with melee weapons by that unit until your next
hero phase.
