Consumption

As part of casting this spell, you must roll 1d6 and take that amount of necrotic damage. This Damage can not be lowered or negated in anyway. Choose a creature within range and roll 1d8. The creature loses a number of hit points equal to the result. For the duration of the spell, the creature must make a Constitution saving throw at the end of each of its turns. On a failure, roll the 1d8 again, and the creature loses hit points equal to the result. On a success, this effect ends for the creature.

When you cast this spell using a spell slot of 2nd level or higher, choose an additional target for the spell for each slot level above 1st.
