Acolyte of Nature

At 3rd level when you select this domain, you learn the druidcraft cantrip. This cantrip is a cleric spell for you.

Overgrowth

Also starting at 3rd level, you can command plants to sprout in an area. As a bonus action, you can choose a point within 30 feet. Plants sprout in a 5 feet radius from the point causing the area to become difficult terrain. The area can be cleared by using one minute per 5 feet square to clear out the plants. You can use this ability a number of times between long rests equal to your Wisdom modifier.

Channel Divinity: Charm Animals and Plants

Starting at 6th level, you can use your channel divinity to charm animals and plants.

As an action, you present your holy symbol and invoke the name of your deity. Each beast or plant creature that can see you within 30 feet of you must make a Wisdom saving throw. If the creature fails its saving throw, it is charmed by you for 1 minute or until it takes damage. While it is charmed by you, it is friendly to you and other creatures you designate.

Dampen Elements

Starting at 10th level, when you or a creature within 30 feet of you takes acid, cold, fire, lightning, or thunder damage, you can use your reaction to grant the creature resistance against that instance of damage.

Weather Chants

At 14th level, you learn the control weather spell and it counts as a cleric spell for you.

Once between long rests, you can also cast one of the following spells without expending a spell slot: call lightning, gust of wind, healing wind, sleet storm, sun flare. When you cast one of these spells with this feature, it is cast as if you had cast it with a 5th level spell slot.
