Harvest Domain.

The Harvest Domain draws from the cycle beginning with creation, reaching abundance, and ending in culling before repeating endlessly. Deities of farming and crops can focus on one of the harvest's aspects, but most draw from each phase of the cycle. Clerics of this domain are drawn to the cyclical nature of existence, and they often take on roles as shepherds of different cycles.
Use the Harvest Rites table for inspiration on observances based on each aspect of the harvest cycle.

Level 1 Features:

Harvest Domain Spells.

Each domain has a list of spells—its domain spells—that you gain at the cleric levels noted in the domain description. Once you gain a domain spell, you always have it prepared, and it doesn't count against the number of spells you can prepare each day.
If you have a domain spell that doesn't appear on the cleric spell list, the spell is nonetheless a cleric spell for you.

Cornucopia.

When you start a short rest, you can magically create a cornucopia filled with enough food for a number of creatures equal to twice your proficiency bonus. When creatures that eat the food finish a short rest, you can distribute a number of d4s equal to your cleric level among creatures who ate the food. Each creature immediately rolls the dice they're allotted and regains hit points equal to the total. The cornucopia and any uneaten food vanish when the short rest ends.
Once you use this feature, you can't do so again until you finish a long rest.

Level 2 Feature:

Channel Divinity: Bountiful Harvest.

You can use your Channel Divinity to magically invoke the spirit of the harvest. As an action, you present your holy symbol, and up to six creatures of your choice within 60 feet of you gain inspiration. A creature must finish a long rest before it can gain inspiration from this feature again.
Additionally, you grant all targets one of the following benefits. If your current harvest aspect is a different one, it changes to match the choice.

Sowing. A target gains a number of temporary hit points equal to your proficiency bonus plus your Intelligence, Wisdom or Charisma modifier.

Growing. Until the end of your next turn, when a target makes an attack roll or ability check, it adds 1d4 to the total.

Reaping. A target deals extra necrotic damage equal to your proficiency bonus the first time it damages a creature before the end of your next turn.

Level 6 Feature:

Blessing of the Seasons.

You can draw upon the powers of the harvest cycle to potentially avert disaster. When a creature you can see within 30 feet of you fails a saving throw of a particular type determined by your current aspect, you can use your reaction to allow it to reroll the d20 and use the new roll. The type of saving throws you can affect are as follows.

Sowing. Dexterity and Charisma

Growing. Constitution and Intelligence

Reaping. Wisdom and Strength

Additionally, after the saving throw succeeds or fails, roll a number of d4s equal to your proficiency bonus. The target regains hit points equal to the total rolled.
You can use this feature a number of times equal to your Intelligence, Wisdom or Charisma modifier (minimum of once), and you regain all expended uses when you finish a long rest.

Level 8 Feature:

Potent Spellcasting.

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

Level 17 Feature:

Channel Divinity: Blood Puppet.

When you use your Bountiful Harvest, you can invoke the endless cycle of life, death, and rebirth to grant yourself and the creatures affected by your Channel Divinity an additional benefit based on your current aspect:

Sowing. Targets gain the effects of the Regenerate spell for 1 minute, or until you lose concentration.

Growing. Targets gain advantage on saving throws and ability checks for up to 1 hour, or until you lose concentration.

Reaping. Targets gain resistance to necrotic, psychic, and poison damage for 1 hour.

Once you use this feature, you can't do so again until you finish a long rest unless you expend a spell slot of 7th level or higher (no action required) to restore your use of it.
