Plague

Choose one enemy unit within 18" of the caster.
Each model must take a Toughness test. If failed,
it suffers a single wound with no armour save
allowed. If cast on a unit in close combat, all
units involved are affected. Then, roll a dice:
1: The opponent can decide to end the spell or
select a new target as if a 5-6 was rolled
2-4: The spell ends.
5-6: The caster can decide to end the spell or
target another unit not yet affected and within
12" of a unit affected by the spell this phase.
