Magic is an energy that suffuses the multiverse and that fuels both destruction and creation. For some gods of magic, magical knowledge is a great responsibility that comes with a special understanding of the nature of reality. Other gods of magic are concerned with mastery of pure power, to be used as its wielder sees fit.
You learn one cantrip of your choice from the Wizard spell list. This cantrip counts as a Cleric cantrip for you, and does not count against the number of Cleric cantrips you know. You can replace this cantrip with another Wizard cantrip of your choice when you finish a Long Rest.
You also gain proficiency with one of the following skills of your choice: Arcana, Investigation, or Medicine. Finally, you gain proficiency with your choice of Alchemist's Supplies, Calligrapher's Supplies, or Herbalism Kits.
You have an Arcane Domain Spells list, composed of spells chosen by you from the Wizard spell list. When you gain a Cleric level that grants a spell slot of a higher level, you thereafter always have the Arcane Domain Spells of that spell level and below prepared and they do not count against your Prepared Spells limit. While a spell is on your Arcane Domain Spells list it is a Cleric spell for you.
When you gain this feature, you choose ten spells from the Wizard spell list, two from each of the following levels: 1st, 2nd, 3rd, 4th, and 5th.
Each time you gain a level thereafter, you can replace one of your Arcane Domain Spells with a different spell of the same level chosen from the Wizard spell list.
As a Magic action you can present your Holy Symbol and expend a use of your Channel Divinity to cast either Arcane Lock or Knock without a spell slot and without need of spell components. If you cast Knock in this way, the loud noise that normally accompanies that spell does not occur.
You can cast Counterspell without a spell slot and without need of spell components by presenting your Holy Symbol and expending a use of your Channel Divinity.
When you gain this feature, you choose four spells from the Wizard spell list, one from each of the following levels: 6th, 7th, 8th, and 9th. You add them to your Arcane Domain Spells list.
