Mortal Contract

Pick 1 enemy unit within 18" of the caster that is
visible to them. For the rest f the battle, roll a
dice at the end of each phase during which any
attacks made by that unit inflicted any damage
on a friendly OSSIARCH BONEREAPERS
unit. On a 3+, that enemy unit suffers D3 mortal
wounds. You cannot pick the same unit to be
the target of this spell more than once per battle.
