Psychic Scream

9th-level Enchantment
Casting Time: 1 action
Range: 90 feet
Components: S
Duration: Instantaneous

As in Xanathar's Guide to Everything with the following note and an upcasting option added:

Instead of causing heads to explode, the spell now reads: If a target is killed by this damage, the resonance of the spell remains, causing any resurrection spell beneath 7th level to fail, and preventing spells like Speak with Dead from communing with the lingering echo of the spirit.

At Higher Levels. When you cast this spell using a spell slot of 10th level or higher, you can target one additional creature for each slot level above 9th.
