Azyrite Halo

Range of 12" if the caster is a KNIGHT or 18" if
the caster is a LORD or DRACONITH. If
successfully cast, pick 1 friendly STORMCAST
ETERNALS unit wholly within range and
visible to the caster. Until your next hero phase,
if the unmodified save roll for an attack that
targets that unit is 6, the attacking unit
suffers 1 mortal wound after all of its attacks
have been resolved.
