Circle of the Storm

While other circles might focus on the sacred nature of grounded forces, druids that devote themselves to the Circle of the Storm understand that the most powerful forces of nature come from the air. Hail, lightning, sand, and drought are all incredibly powerful elements in the hands of the right druid.

Weather Vane

At the 2nd level, you've learned to interpret and replicate patterns within the weather. You know the Druidcraft cantrip, and it doesn't count against your known spells. Furthermore, when you use it to replicate upcoming weather, you can instead forecast it for the next seven days.

Heart of the Storm

You can use your bonus action to expend a use of your wild shape to conjure a storm around you. The storm fills a 15-foot radius centered on you. Choose one of the following Storm Type options: Hail, Lightning, Sand, or Drought. Many features use a damage type that depends on your Storm Type: cold for Hail, lightning for Lightning, bludgeoning for Sand, or fire for Drought. The storm lasts for 10 minutes or until you die. While the storm surrounds you, you gain the following benefits:

• The area of the storm is difficult terrain for any creature besides you.
• Any creature besides yourself that starts its turn in the storm must make a dexterity saving throw against your spell save DC or take damage equal to your wisdom modifier (minimum 1). This damage type depends on your Storm Type.
• You gain an additional use of your Druidcraft cantrip. You can use it to make a melee spell attack towards a creature within 5 feet of you or a ranged spell attack with a range of 60 feet. On a hit, the target takes 1d10 damage, once again of a type based on your Storm Type. This damage increases to 2d10 at the 6th level in this class, 3d10 at the 10th level, and 4d10 at the 14th.

Stormy Resilience

By the 6th level, you've become more resilient while within the storm. While your Heart of the Storm is active, you have resistance to the damage associated with your Storm Type, and you have the benefits of half cover.

Reins of the Tempest

At the 10th level, you've mastered your Heart of the Storm feature. Its radius increases to 30 feet, and you can designate a number of allies equal to your wisdom modifier who can ignore itself.

Undying Storm

Starting at the 14th level, your connection to the storm allows you to channel it through you, animating yourself just a little longer. When you drop to zero hitpoints, you expend a use of your wild shape as a reaction to not fall unconscious, instead activating all four Storm Types simultaneously. You still have zero hitpoints and must make death saving throws as per usual, but you do not fall unconscious from this unless you die. While in this state, when you cast Druidcraft, you can make four attacks instead of one, each one representative of a different Storm Type. This state ends if you regain any hitpoints or are incapacitated.
