You are dedicated to the deities of the tastiest snack ever to be created: garlic bread. Or perhaps, instead, you are simply dedicated to its ideals or the idea of the holy bread itself. Either way, you believe in feeding the hungry and bringing garlic bread to all who need it. You stand against injustic, tyranny, and the evils that all garlic bread haters - like vampires - try to bring forth.

Note:

Since DnD Beyond is not allowing me to publish this with all the additionall spells, I have not put them in the "Additional Specific Spells" section.

 7th - aura of purity, sickening radiance

This is a DnDBeyond verison for the Garlic bread domain from r/UnearthedArcana, posted by u/lady_of_luck. Which was inspired by WilloTehKitsune here on DnDBeyond. I have made a few small changes in the language.

 

Bread Knife Expert

At 1st level, you become proficient with martial weapons and cook's utensils. If you are already proficient with cook's utensils, you instead become proficient with one of the following in order to make the drinks or dishware to accompany your meals: alchemist's supplies, brewer's supplies, glassblower's tools, herbalism kits, or potter's tools. Cook's utensils can serve as a holy symbol for you.

Divine Baker

As an action, you can casue a piece of scrumptious garlic bread to appear in one of your free hands. The piece remains toasty and delicious until the end of your nest long rest, when it turns into a sprinkle of garlic powder. A creature can eat one of these pieces of bread as a bonus action to regain hit points equal to 1d4 + your Wisdom modifier. You can use this feature a number of times equal to your Wisdom modifier (a minimun of once). You regain all expended uses when you finish a long rest.

Channel Divinity: Satiate Hunger

Starting at 2nd level, you can use Channel Divinity to feed those who need it. As an action, you present your holy symbol to unleash a wave of food power. Choose up to 10 creatures within 30 feet of you (possibly including yourself). Each creature becomes comfortably full and gains both enough nutrients to survive for 24 hours without additional food and temporary hit points equal to 1d8 + half of your cleric level.

Channel Divinity: Food Coma

Starting at 6th level, you can use your Channel Divinity to curse a creature as of they had overindulged. As an action, you present your holy symbol and target one creature you can see within 30 feet of you. They must succeed on a Constitution saving throw or gain one level of exhaustion. If they had no levels of exhaustion prior to you using this ability, they instead gain two levels on a failure. 

Garlic Strike

At 8th level, you gain the ability to infuse your weapons strikes with garlicky energy. Once on each of your turns when you hit a creature with a weapon attack, you can cause the attack to deal an extra 1d8 acid damage to the target. The damage increases by 1d8 if the target is an undead.

This spell's damage increases by 1d8 when you reach 14th level (2d8). Additionally if the target is an undead, the damage is increased by 3d8.

Delicious Vengeance

At 17th level, you gain the ability to cast power word kill once without expending a spell slot. It is not added to your spell list and cannot be prepared, but it counts as a cleric spell for you during its casting. When cast using this feature, the spell can only target a creature that has dealt damage to you since the start of your last turn. Once you use this feature to cast the spell, you can't use it again until you finish 1d4 long rests.
