ARCANE BOLT

Arcane Bolt is a spell that has a casting value of 5
and a range of 12". If successfully cast, at the
start of any 1 phase before your next hero phase,
you can pick 1 enemy unit within range and
visible to the caster. That unit suffers 1 mortal
wound. If that unit is within 3" of the caster,
it suffers D3 mortal wounds instead of 1.
(The caster calls forth a ball of crackling arcane
energy that hovers above their outstretched hand,
ready to be hurled at a foe)
