Advance Ritual (Costs 3 Actions). Ultima invokes the aether from the Heart of Sabik to erupt. Energy reverberating through the air begins to strain reality as the Seraph's True Resurrection draws near, forming cracks in the fabric of space.

Invocation #1- "Misfortune hangs heavy on a head once held high. Such is poor cover for when the Heavens fall!"

A tether of energy forms between the Virgo Demon and the Abysswalker sending out a shockwave that deals 2d10 force damage. All creatures within 300 ft must make a Constitution saving throw (DC 20) and are knocked back 5 ft away from the Virgo Demon on a failed save.

Invocation #2- "Open your eyes to the darkness and drown in its loveless embrace. The gods will not be watching."

The void begins seeping through ever widening tears in reality. You hear a voice calling out to you, promising power and sanctum. "Dear children of Etheirys, your God draws near." Another shockwave erupts, dealing 3d8 psychic damage to all creatures within 300 ft. All creatures must make a Constitution saving throw (DC 20) and are knocked back 5 ft away from the Virgo Demon on a failed save.

Invocation #3- "Simmer does the light of life before rising to the Heavens in a cleansing conflagration of Divine Benevolence."

 All remaining auracite crystals shatter and swirl around the Virgo Demon and Abysswalker. Their forms glow in a blinding green glow as the High Seraph takes form once again. All creatures in a 300 ft radius are stunned as a final shockwave crashes through reality.
