Some who seek divine magic seek it by their own selfish means. Others do not seek to worship but instead merely seek the might of the gods. And others yet, wish to become a god themselves.

All of these are examples of those who might study magic, gaining divine magic not through worship and respect, but through the pursuit of knowledge and their own gravitas. These are the arcane heretics.

Borrowed Knowledge

Beginning when you select this school at 2nd level, you are capable of learning spells from the Cleric spell list. Each time you gain a Wizard level, you can elect to take a spell from the Cleric spell list as one of your two spells. 

Additionally, you can add Cleric spells to your spellbook, however, it takes twice the time and money to do. For example, a 1st level Cleric spell would cost 100 gp and take 4 hours to copy.

When you reach 18th and 20th level, you cannot choose healing spells as you Spell Mastery or Signature Spells.

Hallowed Inspiration

Your god-like powers are inspiration to all those that stand with you. At 6th level, when you successfully hit a creature with a spell attack, you may grant an ally within 30ft of you advantage on their next attack roll, be it a weapon attack or spell attack.

You may use this feature a number of times equal to your Intelligence modifier (minimum of one) per long rest.

Prophet’s Presence

Your honeyed words, lofty aspirations and divine powers often garner you support and admiration from those around you. At 10th level, as a bonus action for a duration of one minute, you project a 15ft aura around yourself forcing anyone you can see and designate to make a Wisdom saving throw against your spell save DC.

On a failure, they are Charmed by you for as long as they are within the radius, and for 24 hours after they leave it. Charmed creatures cannot harm you and feel compelled to aid and worship you. On a success, they gain immunity to this effect for 24 hours. This feature can be used a number of times per long rest equal to your proficiency bonus.

Messiah

At 14th level, you have gained access to immeasurable power as you strive for divine might. You are capable of tearing open a rift to the realm of the gods, granting yourself incredible power for one minute. The following effects occur:

• You have advantage on all saving throws.
• Your spell attacks have advantage and saving throws against your spells are made at disadvantage.
• Roll a percentile dice. On a 10 or lower, a stray god wanders through the rift. Whether they see you as an annoyance or ally depends on your actions. The deity’s identity is designated by your DM.

After this rift disappears, you gain a point of exhaustion. 

This ability can be used once per day.
