Damnation

You point at a creature within range, and a black hole opens inside of them. It deals 2d10+3 damage, and does an additional 2d10 if cast at a higher level. If you bring a target to zero hit points or otherwise kill the target with this spell, the following event happens:

The target is dissassembled on a molecular level and pulled into the abyssal portal inside them, and instantly killed, as are the components of the spell. The creature's soul is damned to the 99th level of the Abyss and sent directly to your Patron. They drop any items they were holding or wearing, and no trace of their physical body remains. You gain a number of hit points equal to the damage dealt with the spell.
