Death

You can point at one enemy, and speak the word of death, and Death will appear. The enemy will have to make a Constitution save with a DC of 8 + Your Spellcasting modifier + your proficiency bonus + 3. On a succeed, they will take 20d8 + 10d4 damage + 3d10 necrotic damage. If they fail, then Death will take them to the underworld.

You may use this spell 3d100 times. If you cast a spell one more time after that, Death will take you to the underworld. He is sick of you calling him up. However, in your next life, you can choose to get either Prismatic wall or Meteor Swarm as a First Level Spell, regardless of class. If your class does not normally cast spells, it uses Wisdom to cast spells.
