Song Domain

The Song Domain mainly follows gods that hold dominion over music and art, such as Correlon, Olidammara, Branchala or Apollo. Their duty is to shareart, music and beauty throughout the world, bringing peace and unity to whatever community they serve. Some clerics choose to follow this domain even when their god isn't directly connected to arts, thereby becoming heralds of their gods teachings, tasked with spreading the word of their deity to bring them more followers.

Bonus Proficiency

When you choose this domain at 1st level, you gain proficiency in the Performance skill and three musical instruments of your choice.

Words of Comfort and Terror

Also starting at 1st level, you learn how to counteract mind-altering effects of your enemies. Whenever a creature within 30 feet of you makes a Wisdom saving throw, you may use your reaction to grant that creature a bonus to that saving throw equal to your Widsom modifier. 

Alternatively, whenever a creature within 30 feet of you fails a Wisdom saving throw you may use your reaction to make that creature frightened of you until the end of your next turn.

You may use this feature a number of times equal to your Wisdom modifier. You regain spent uses after you finish a long rest.

Channel Divinity: Preacher's Presence

Starting at 2nd level, you can use your Channel Divinity to empower your words. As an action, you tap into the blessing from your god. For 10 minutes, you may add your Wisdom modifier to all Charisma checks you make.

Blessed Hymn

Beginning at 6th level, you can grant a powerful blessing through a hymn dedicated to your god. As an action, you may start playing an instrument or singing a song. Choose a number of creatures that can hear you within 120 feet of you equal to your Wisdom modifier. Until the end of your next turn, those creatures may add 1d6 to one attack roll, one damage roll, one ability check and one saving throw they make. You may use your action on your following turns to continue playing or singing that song, keeping the blessing active, but it can only last up to one minute and you cannot prolong the blessing on a creature that left the 120 ft range or cannot hear you.

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

Potent Spellcasting

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

Supreme Hymn

Starting at 17th level, when you use your Blessed Hymn feature, the bonus granted from it changes from 1d6 to 1d10 and you can prolong that feature for up to one hour. In addition to that, any effect that would restore hit points to a creature affected by Blessed Hymn now restores the maximum possible amount and those creatures gain a +2 bonus to AC.
