Holy Scourge

The Holy Scourge
Sorcerers have been of dubious relation to the devotees of the Goddess for as long as anyone can remember. The pursuit of arcane power usually leads to arrogance and power-thirst, and ends up an enemy of the church, because they are an enemy of everybody after all. But a rare few balance devotion to the Goddess with their arcane pursuits, imbuing their spells with divine power.

Righteous Evocation
The Holy Scourge's spells are blessed by the Goddess. Well, probably. They have a degree of holy power imbued in their spells. At 8th level, the Holy Scourge adds 1d6 radiant damage to their evocation spells. In addition, they gain the Sacred Spell metamagic option.
 * Castigating Spell: When the Holy Scourge casts an evocation spell, they can spend 1 sorcery point. The spell deals both the original damage, as well as radiant; it deals whichever damage is most advantageous (so a Sacred Fireball would deal divine damage if a creature were resistant to fire but not radiant). The spell has advantage on attack rolls against evil creatures, if it is a spell that requires an attack.
 * Sacred Spell: When the Holy Scourge casts an evocation spell that forces a creature to make a saving throw, evil creatures targetted by the spell take disadvantage on the first saving throw against it.

Arcane Smite
The Holy Scourge may not be a divine warrior, but they can show conviction comparable to a Paladin when faced with the forces of evil! At 13th level, when they cast an evocation spell, the Holy Scourge can spend 2 sorcery points to add 1d4 radiant damage per level of the spell. This effects one target of the spell. The spell adds 1d6 per spell level against evil creatures.

Wrathful Prophet
The Holy Scourge has become a force of destructive light against the forces of darkness! At 18th level, the Holy Scourge adds the following spells to their list of spells known - Fire Storm, Earthquake, Control Weather, Sunburst, Tsunami, Storm of Vengence, Meteor Swarm. Once per long rest, the Holy Scourge can cast one of these spells without expending any spell points or daily uses of high level spells. Metamagic can be applied to this spell normally.
