The School of Deiology

Deiology is the arcane study of the gods and how their powers work. Practitioners of Deiology known as false clerics have mastered the art of faking faith to deities in order to gain access to their divine spells. This path is a dangerous one, as it is essentially cheating the gods, but it allows for a mortal to gain great power as long as their deception goes undetected. Powerful false clerics can even fake faith in multiple deities at once.

Divine Spells

Starting at 2nd level upon choosing this school, you are able to learn divine spells. One of the two spells you learn from leveling up can be from the cleric spell list. These spells are prepared and cast as wizard spells using your intelligence modifier. You are able to learn cleric spells from scrolls. Upon gaining this feature you learn one cleric cantrip and may replace one of your wizard cantrips with another cleric cantrip.

Fake Devotion

Starting at 2nd level, during a long rest you may fake faith in a god that has a domain in one of the official sourcebooks. Until you change your faith you have access to that domain's channel divinity feature which you can use once per long or short rest. The number of times you may use the channel divinity feature per rest increases to twice per rest at 6th level and three times per rest at 18th level. Whenever you fake faith in a different god, roll a percentile die. If the result is equal to or lower than half your wizard level, the deity and it's followers become hostile to you and you are no longer able to fake faith to that deity.

Applying Divine Casting

You discover how to apply faith based casting to your spells. Starting at 6th level you may add your wisdom modifier to your spell attack rolls and half your wisdom modifier to your save DC.

Self Brainwashing

Starting at 10th level, once per long rest you may automatically succeed the percentile roll for successfully deceiving your deity. When you gain this feature you show zealous faith allowing you to learn three cleric spells that you have spell slots for that are always prepared without counting against your normal number of prepared spells. You may change these spells on a long rest.

Split Mind and Faith

Starting at 14th level you have mastered the art of zealously keeping faith in two different gods at the same time. You may use channel divinity independently for each of them.
