Wither

Wither has a casting value of 7. If successfully
cast, pick 1 enemy unit within 13" of the caster
and visible to them, and roll 2D6. If the roll is
greater than that unit’s Wounds characteristic,
that unit suffers D3 mortal wounds. In addition,
if the roll is greater than that unit’s Wounds
characteristic, subtract 1 from hit rolls for attacks
made with melee weapons by that unit until your
next hero phase.
