The Will of the Reaper

After successfully completing a ritual for 1 hour and offering bones to a deity of death, the deity blesses the caster's weapon. The weapon can be wielded to critically strike a single enemy within sight that is under 5 HP or 5% HP or lower. The weapon will fly from the wielder's grasp and strike-to-kill a chosen creature at 100ft Flying Speed.

The spell is meant to secure kills before an enemy has a chance to escape.

The critical strike effect will apply for 3 strikes against the chosen target or until the target is dead.

The weapon will not fly to the target unless it is 5 HP or 5% HP or lower.
