Portent of Doom (6)

18" / Hex / Permanent
{9} : 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.
