The Theurge

A school of magic usually practiced by sages and monks from religious background, the Theurges are wizards who learn to mix arcane and divine power in their repertoire. They sacrifice specialization for strong versatility and can learn to actually combine both strands of magic when situations truly require it. 

Delver of Magic

At level 2 you can change a Cantrip you know for a Cleric Cantrip of your choice. Every time you gain a Cantrip you can choose a Cleric Cantrip instead of a Wizard one.

From level 2 onward when you gain a level, one of the spells you learn must be a spell from the Cleric list and one of the Wizard list. All cleric spells use your Intelligence modifier and count as Wizard spells, which are inscribed on your spellbook. You are now capable to write Cleric scrolls into your spellbook as if they were wizard spells. You learn Cleric spells the exact same way you would learn a Wizard spell.

 

Divine Magician

At level 6, when you use a spell slot higher than a level 1 slot, you can choose two spells of a lower level to be cast. One must come from your Divine spells and the other must be an Arcane spell. For example, if you use a 3rd level spell slot, you can cast a 2nd level Arcane spell and a 1st level Divine spell.

When using this ability you can only cast spells that have the same target (area, one target, self, etc...) and both spells must be inside their maximum range. The spells cannot take more than one Action to cast, but using this ability will cost you both your Action and your Bonus Action.

Both spells will target the same point in an area or the same target of the spell. If the spells have an area of effect, the area for both spells is equal to the area of the smallest spell.

If a target would have to roll a saving throw, they must roll one for each spell separately. You cannot use Cantrips with this ability. Once you use this ability you cannot use it again until you finish a Short Rest.

 

Theurge Savant

At level 10 when you use your Divine Magician ability, you can spend an additional spell slot to increase the DC of the saving throw against both spells by the number of the spell slot used. The spell slot expended cannot be higher than half your proficiency bonus rounded down. You can also use Divine Magician twice per short rest.

 

Mystic Apotheosis

At level 14 you can keep concentration on two spells at the same time, as long as one spell is Arcane and the other is Divine. You can also use Divine Magician three times per Short Rest.
