Amphibious. The hag can breathe air and water.
Curse. A creature that makes a bargain with the hag is magically cursed for 30 days. While it is cursed, the target automatically fails saving throws against the hag’s scrying and geas spells, and the hag can cast control weather centered on the creature.
Expanded Spellcasting. The bay witch can cast augury at will.
Innate Spellcasting. The hag’s innate spellcasting ability is Charisma (spell save DC 13). It can innately cast the following spells, requiring no material components:
At will: dancing lights , disguise self
1/day: control weather , geas , scrying
ACTIONS
Claws. Melee Weapon Attack: +5 to hit, reach 5 ft., one creature. Hit: 10 (2d6 + 3) slashing damage.
BONUS ACTIONS
Terrifying Visions. The witch sends waves of visions, filling its enemies minds with images of their own death. This ability operates identically to Horrific Transformation except that creatures failing the save gain an expertise die on their next Wisdom or Dexterity saving throw , guided by the premonitions of the future.
Reactions
Foretelling (Recharge 5-6). When a bay witch is attacked or forced to make a saving throw it can draw on its kaleidoscope of visions to foresee the outcome. The bay witch gains advantage on its next saving throw and its AC increases by 3 until the start of its next turn.
Sometimes a sea hag develops the ability to see the future, visions dancing around every individual they meet. As this power grows, the overwhelmed hag tends to become more and more solitary, even to the point of abandoning its coven. Ultimately this effect clouds the hag’s sight, leaving it blind to all but the visions.
When receiving visitors, a bay witch will agree to foresee their future for a price. These visions often seem innocuous, but will have some terrible meaning that will only become apparent.
