Vecna's Lament

You launch a black pulsing ray at a target you can see within range. The target can be a creature, a nonmagical object, or a creation of magical force, such as the wall created by Wall of Force.

This beam of dark energy forms a line 200 feet long and 5 feet wide blasts out from you in a direction you choose. The beam stops when it impacts a creature, object, or creation of magical force, such as the wall spells.

If the beam reaches a creature, they must make a Dexterity saving throw. On a successful save, the beam passes by the creature, and continues until it reaches another obstacle. On a failed save, the beam impacts the creature, and they take 20d12 +45 force damage. The target is annihilated if this damage leaves it with 0 hit points. An annihilated creature and everything it is wearing and carrying, including magic items (but not artifacts) are disintegrated into gray dust. This spell automatically annihilates a Huge or smaller non magical object, when this spell targets a magic creation or magical object that can take damage it annihiilates a 50-foot-Cube portion of it.. The target can be revived only by a True Resurrection or a Wish spell..
