Description
As part of casting this spell, you must expend four Hit Point Dice or the spell automatically fails. Make a melee spell attack against a creature within 5 feet using the Material component of this spell. On a hit, roll the Hit Point Dice expended to cast the spell plus 4d8. You deal Necrotic damage equal to the roll's total. If this damage causes the creature to be reduced to 0 Hit Points, it immediately dies and you gain one of the following dark blessings of your choice. When you take Radiant damage while you have a dark blessing, you take an extra 1d4 Radiant damage.
Your dark blessing ends after 10 minutes or when you are reduced to 0 Hit Points, whichever happens first.
