The arrow turns black as the midnight sky as you finish the incantation.

A creature struck by the projectile must succeed on a fortitude save or be instantly slain. Spell resistance applies against the death effect, as does immunity or resistance to death or necromancy effects. The projectile remains so enhanced only until the end of the current turn. If the projectile does not hit a creature before the end of the turn, the spell drains away harmlessly.
