Subclass Druid Circle of the Sea
The Circle of the Sea is a Druid subclass that channels ocean storms as a combat aura. Wrath of the Sea at Level 3 lets you expend a Wild Shape use to generate a 5-foot ocean spray Emanation that debuffs nearby enemies with cold and lightning effects. Aquatic Affinity at Level 6 doubles the Emanation radius to 10 feet. Stormborn at Level 10 adds two additional benefits while the Wrath of the Sea aura is active. The Circle also expands the Druid's spell list with cold, lightning, and storm spells.

Wrath of the Sea As a Bonus Action, you can expend a use of your Wild Shape to manifest a 5-foot Emanation that takes the form of ocean spray that surrounds you. It ends early if you dismiss it (no action required), manifest it again, or have the Incapacitated condition.
Aquatic Affinity The size of the Emanation created by your Wrath of the Sea increases to 10 feet.
Stormborn Your Wrath of the Sea confers two more benefits while active, as detailed below.
The Circle of the Sea is the sustained-aura elemental Druid. Wrath of the Sea creates a persistent ocean spray around you that affects every creature that starts their turn or moves within range — the cost is one Wild Shape use per activation. Since Wild Shape recovers on Short Rest, this gives the Sea Druid an effective combat resource that refreshes frequently.
The spell list covers weather and water control: Fog Cloud for obscurement, Thunderwave for push + damage, Gust of Wind for forced movement, Lightning Bolt at Level 5 for reliable burst damage. Hold Monster at Level 9 is a concentration-based hard disable. Combined with a spellcaster build, the Sea Druid can use the Wrath of the Sea aura offensively while controlling the battlefield with weather and debuff spells.
Aquatic Affinity at Level 6 doubles the Emanation from 5 feet to 10 feet — effectively doubling the area covered and the number of creatures affected on a typical battlefield. Stormborn at Level 10 adds passive benefits while the aura is active, further rewarding sustained activation.
This subclass pairs well with Potent Spellcasting from Elemental Fury at Level 7, adding Wisdom modifier to Ray of Frost damage to complement the cold/lightning theme.
