Vecna's dark gaze

Dark smoke pours from your eyes as you gaze deep into any creature in your sight. All creatures in your gaze that you choose must make a DC 19 constitution saving throw or take 8d10 cold damage and 12d10 necrotic damage. On a successful saving throw up to two creatures of your choice are paralyzed by visions of death, rot, corruption, and damnation. These creatures can do nothing but scream and beg for the next two turns or until they are healed by a greater restoration spell. When you cast this spell roll 1d20, on a roll of a 20 the demon lord Orcus is alerted to such powerful necromancy and sets two Balor and 12 skeletons upon the caster, they appear within the caster's sight and will attack everything that is living.
