Feat: Annihilating Compound Invocation

Each tradition of magic holds sway over two of the four essences that make up all of creation, and so by invoking runes from each tradition at once, you can pull from the four corners of magic to unravel anything. You invoke four runes of your choice, each of which must be from a different tradition of magic. In addition to the runes' normal effects, one creature within 30 feet of all invoked runes must attempt a basic Fortitude saving throw, taking 10d4 force damage on a failure as destructive magical reverberations clash in their body. If reduced to 0 Hit Points by this damage or by the damage of any of the runes invoked, the creature's body is torn apart into glowing script that describes the creature to the smallest detail, leaving no remains as the letters fade. The creature's gear is unharmed.
