Tending of nature and its creatures are part of many druids lives, but balance between what is nurtured and what is culled must be maintained as well. Druids who join this circle see it as their duty to perpetuate the cycle of life by destroying that which is ill or a drain on the land to make way for new life. Much in the same way a farmer will burn a field for a more fertile crop, druids of the harvest strive to create a stronger world.

Bonus Cantrips

When you choose this circle at 2nd level, you can learn one cantrip from the sorcerer spell list. This cantrip counts as a druid spell for you. 

Call of the Harvest

Starting at 2nd level, as a bonus action on your turn you imbue your attacks and spells with primal fury. For 1 minute, whenever you deal damage with a weapon or spell attack, add 1d6 to the damage roll. You can use this feature twice. You regain expended uses at the end of a short or long rest.

This die increases to a d8 at 5th level, d10 at 11th level, and d12 at 17th level.

Cull the Weak

At 6th level, you are able to weed out the sick from the healthy. You always have Detect Poison and Disease prepared, and it doesn't count against the number of spells you can prepare each day. You can cast this spell once without using a spell slot and regain the ability to do so after completing a short or long rest.

When you make an attack roll against a creature that is poisoned or diseased, you have advantage on the roll.

Cleansing Cycle

When you reach 10th level, you are able to improve the health of one creature in exchange for the life of another. After reducing a creature to 0 hit points, you can use your bonus action to restore hit points equal to your druid level to a creature within 60 feet of you. A creature that is healed in this way is cured of one disease and one condition. The conditions that can be cured are blinded, deafened, paralyzed, or poisoned.

Reaper's Stand

At 14th level, your cleansing of the land has transformed you into a bastion of renewal. When you are reduced to 0 hit points, you are immediately restored to life with 1 hit point and temporary hit points equal to your druid level.

As a reaction to being reduced to 0 hit points, you can cast a cantrip that has a casting time of 1 action.

Once you have you used this feature to return to 1 hit point, you must finish a long rest before you can do so again.
