Blood Eclipse

You blot out the sun in a 1-mile radius, plunging the area into a magical eclipse of crimson shadows. The skies weep blood, the dead claw from their graves, and life itself recoils. While under the Blood Eclipse: Undead Empowerment: All undead within the area gain advantage on all attack rolls, saving throws, and cannot be turned or banished by any means. Living Decay: Every living creature that starts its turn within the area must succeed on a DC 22 Constitution saving throw or take 10d12 necrotic damage, half on success. Blood Puppeteer: You can animate and control up to 10 corpses as blood-bound revenants (CR 5 or lower), which remain loyal for the spell's duration. Spell Surge: Once during the spell, as a bonus action, you can cast any necromancy spell of 8th level or lower without expending a spell slot or material components. Sanctuary of the Crimson Eye: While concentrating on this spell, the caster cannot be killed. When reduced to 0 HP, the caster remains conscious and functioning, but begins bleeding from their eyes, ears, and mouth. If the caster fails a DC 22 Constitution saving throw at the start of their turn, they disintegrate into blood and the spell ends immediately.
