Portent of Doom

Hex, Permanent, 18"
When calculating Combat Score, a side with units
containing at least one model affected by the spell
suffers −X to its Combat Score (for each affected
unit and instance of the spell), where X is equal
to the number of Characters in the unit, increased
by 1 if the unit contains any R&F models.
A Character leaving a unit affected by the spell
no longer is affected by the spell, unless
the Character was a single model unit that was
the initial target of the spell.
