Legendary Actions

As Water. The sea fury transforms into a wave of foaming seawater, along with whatever it is wearing or carrying, and moves up to its speed without provoking opportunity attacks. While in this form, it can't be grappled or restrained. It reverts to its true form at the end of this movement.

Fearsome Apparition (Costs 2 Actions). The sea fury conjures an apparition of one of its dead sisters, which appears in an unoccupied space the sea fury can see within 30 feet of it. Enemies of the sea fury that can see the apparition must succeed on a DC 16 Wisdom saving throw or be frightened of it until it vanishes at the end of the sea fury's next turn.

Conjure Snakes (Costs 3 Actions). The sea fury disgorges a swarm of poisonous snakes, which occupies the same space as the sea fury, acts on its own initiative count, and attacks as directed by the sea fury. The sea fury can control up to three of these swarms at a time.

Lore

In times of great danger, sea hags form massive covens to channel powerful magic against outside threats. But when the threat is vanquished, these covens often destroy themselves from within. One sea hag grows more powerful than the others, killing its kin one by one and siphoning their magical power as it does so.
