Dream Domain

Imaginary friends are important, you know that better than anyone else.

Imaginary Friend

When you choose this domain at 1st level, you are able to conjure a creature from your imagination. You learn the Find Familiar spell and can cast it without material components. When you cast this spell, your familiar can take on the appearance of any tiny creature or have an ethereal form. Regardless of the form you choose, your familiar is an aberration and uses the Imaginary Friend statblock.

Channel Divinity: Hush Now

As an action, choose a number of creatures equal to your proficiency bonus that you can see withing 60 feet of you. Those creatures must make a Charisma saving throw or be silenced for one minute or until you lose concentration (as if concentrating on a spell). A silenced creature cannot speak and cannot cast spell that require verbal components.

Dream A Little Dream

Starting at 6th level, at the beginning of a long rest, choose a number of creatures equal to your proficiency bonus within 30 feet of you. When those creatures complete their next long rest, they gain a 1d8 dream die until they take their next long rest. The creature can roll the die and add the number rolled to one ability check, attack roll, or saving throw it makes. The creature can wait until after it rolls before deciding to use the dream die, but not before the DM determines the outcome. Once the dream die is rolled, it is lost. Beginning at 10th level, the die increases to 1d10 and at 16th level, it increases to 1d12.

Potent Spellcasting

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

Dream Form

When you reach 17th level, you can assume a form of nightmares and dream. As an action, you can merge with your Imaginary Friend and assume your dream form for one minute or until you are incapacitated. While transformed you gain the following benefits:

• You have resistance to all damage.
• You gain the Incorporeal Movement trait.
• You gain truesight to a radius of 60 feet.
• You gain a flying speed equal to your walking speed and can hover.

Once you use this ability, you cannot use it again until you finish a long rest.
