Blinding Starlight

Blazing Starlight is a spell that has a casting value
of 6 and a range of 18". If successfully cast, pick 1
enemy unit within range and visible to the caster.
Until your next hero phase, subtract 1 from hit
rolls for attacks made by that unit.
The Starpriest summons the blazing light of a distant celestial body and uses its radiance to blind the foe.
