Ultima

A blazing arc of magickal energy tears from your hands. As it impacts far away it blossoms into a bright flash of pale green light and swirling chaotic energies, disintegrating everything within.

This spell produces a powerful explosion of disintegrating energy. All creatures within range must make a CON saving throw. On a failed save, they take 20d6 FORCE damage, and half damage on a successful save.

On a failed save, if this damage reduces a creature to 0 HP, it is disintegrated.

A disintegrated creature and everything it is wearing and carrying, except magick items, are reduced to a pile of fine gray dust. The creature can be restored to life only by means of a Resurrection spell or similar. This spell automatically disintegrates a nonmagickal object, a magickal object with rarity of uncommon or lower, or a creation of magickal force within its radius.

A magick item with a rarity greater than uncommon is unaffected.

The magick is so powerful that it deals 8d6 ARCANE damage to you as it leaves your fingertips, which cannot be reduced.
