(Amplified) Helios, Ultimate Cleric

Lore
The combination of holy and dark energies generated a new sort of power, maturing Helios' body. The dragon surveyed her altered form with trepidation. However, despite her fearsome weapon, she appeared not to be defending herself in the least. Reassured that victory would be his, the dragon swooped down to attack when he noticed his body had been cloven in half. It was only natural for Helios to show such composure, for the battle had already been won.

Name origin
Helios (Ancient Greek Hēlios, latinized as Helius) was the personification of the Sun in Greek mythology. Helios was described as a handsome god crowned with the shining aureole of the Sun, who drove the chariot of the sun across the sky each day to earth-circling Oceanus and through the world-ocean returned to the East at night.
