I wasn’t thrilled with the Unearthed Arcana implementation of the Mystic Theurge as the Theurgy School for wizards, so this is intended to come at it from the other direction.

Certain gods view mystical knowledge as a sacred journey rather than a gift of service. Instead of opening themselves up to all the possible prayers available to their deity, their followers instead write their scriptures down, notate them, and try to glean new meaning from the magical forms inherent in the words of faith. This special form of devotion makes them seem much like wizards to others of the faith, obsessed with books. But it is hard to deny that this obsession gives them access to magic beyond that available to their peers.

Mystic Domain Spells


Mystic Spellbook

Unlike other clerics, you cannot prepare spells from the full cleric list. Instead, you maintain a mystic spellbook that contains the cleric spells you know, and you can prepare spells from this book. At 1st level, your book contains five 1st-level spells from the cleric spell list, and one additional 1st-level spell from either the cleric spell list or the wizard spell list. Each time you gain a cleric level, you can add two cleric spells of your choice to your mystic spellbook (each must be a level for which you have spell slots).

In addition to the spells you gain from leveling, you may copy spells in the mystic spellbook using the rules for wizard spellbooks on page 114’s sidebar. You can freely copy spells from wizard spellbooks (but must still follow the limitation of wizard-only spells per level) and from either arcane or divine scrolls (as long as the spell appears on the cleric or wizard list) using the rules for copying scrolls.

You may copy a cleric spell into the book if you are mentored by another cleric who is willing to explain it to you for the entire time it takes you to copy the spell (the teacher must cast it for you at the completion of the demonstration). The cost for copying in this way is the same as copying from a wizard’s book.

While you are not limited in the number of spells from the cleric spell list you can add to your mystic spellbook, for any particular spell level it cannot contain more spells that do not appear on the cleric spell list than your Intelligence bonus (minimum 1): this sets the limits of your capacity for understanding outside your sphere. For example, if your Intelligence bonus is +2, you may copy up to two spells at each spell level that appear on the wizard spell list but not on the cleric list.

Mystic Spellcasting

Using your normal preparation slots (Wisdom modifier + cleric level), you may only prepare spells from the mystic spellbook that normally appear on the cleric spell list.

Instead of the normal spells gained from a divine domain, you gain one additional prepared spell per cleric level (maximum of 10) that can be used to prepare any spells in your mystic spellbook.

Arts of the Wise

At 1st level, you gain an additional cantrip that can be from the cleric or wizard list (it is treated as a cleric cantrip for you). You also become proficient in Arcana.

Channel Divinity: Mastery of Magic

Starting at 2nd level, you can use your Channel Divinity to exert mastery over the fabric of magic itself.

As an action, you present your holy symbol, and all creatures or items with active spells or inherent magic within 30 feet of you acquire a visible, glowing aura similar to what you would see if you cast Detect Magic. This field lasts for Concentration, up to 10 minutes, and travels with you. Anyone seeing these auras who is trained in Arcana (or who can cast Detect Magic) can identify the school of magic for each effect.

This effect gains additional powers as at 6th level, as described below.

School Focus

Starting at 6th level, choose one of the eight schools of magic as your focus. The gold and time you must spend to copy a spell of that school into your mystic spellbook is halved, and if you use one of your spell choices from leveling up to pick a spell of that school, you instead learn two spells of that school.

Additionally, when you use your Channel Divinity: Mastery of Magic, you may choose to take an action at any point while the effect is active to target a creature or item that is being affected by an effect of your focus school (and which has been identified by the Channel Divinity). The target is treated as if you had cast Dispel Magic upon it. This spell is of a power level as if you had cast it at your highest level spell slot. The Channel Divinity ends upon using this power.

Potent Spellcasting

Starting at 8th level, you add your Intelligence modifier to the damage you deal with any cleric cantrip.

Spell Synthesis

At 17th level, you discover deep secrets of the similarities of magic. On the same round you have used your action to cast a spell from one spell list (cleric or wizard), you may use your bonus action to cast a cantrip upon at least one of the same targets as the spell. You may do this a number of times equal to your Intelligence modifier before completing a short or long rest.
