Death sentence

With the help of fragmented souls stored in the lantern the caster can imbue a whip like weapon with soul energy.

by doing this you may add 10ft to the range of the whip for 1 attack and deal 1d4 extra radiant damage.
as an added bonus the unfortunate souls this attack landed upon must make either a dexterity or strength saving throw or be pulled 10 ft towards the caster.

if this lands a killing blow you can refund the soul cost
