Theurgy: Starlight

A wizard who undertakes the guidance of the stars

Arcane Initiate

Beginning when you select this tradition at 2nd level, whenever you gain a wizard level, you can replace one of the wizard spells you add to your spellbook with a cleric domain spell for your chosen domain. The spell must be of a level for which you have spell slots.

If you add all of your domain spells to your spellbook, you can subsequently add any spell from the cleric spell list instead. The spell must still be of a level for which you have spell slots.

Any cleric spell you gain from this feature is considered a wizard spell for you, but other wizards can’t copy cleric spells from your spellbook into their own spellbooks.
