Sea Hag

A sea hag adds Humanoid Form, Mariner's Curse, and Water Walk to their coven's spells. Their spell DC when leading a coven is 20. This monster can form a coven with two or more other creatures who also have the coven ability. This involves performing an 8-hour ceremony with all prospective coven members. After the coven is formed, each of its members gains elite adjustments, adjusting their levels accordingly. Coven members can sense other members' locations and conditions by spending a single action, which has the concentrate trait, and can sense what another coven member is sensing as a two-action activity, which has the concentrate trait as well. Covens also grant spells and rituals to their members, but these can be cast only in cooperation between three coven members who are all within 30 feet of one another. A coven member can contribute to a coven spell with a single action that has the concentrate trait. If two coven members have contributed these actions within the last round, a third member can cast a coven spell on her turn by spending the normal spellcasting actions. A coven can cast its coven spells an unlimited number of times but can cast only one coven spell each round. All covens grant the 8th-rank Cursed Metamorphosis spell and all the following spells, which the coven can cast at any rank up to 5th: Augury, Charm, Clairaudience, Clairvoyance, Dream Message, Illusory Disguise, Illusory Scene, Scouting Eye, and Talking Corpse. Individual creatures with the coven ability also grant additional spells to any coven they join. A coven can also cast the Control Weather ritual, with a DC of 23 instead of the standard DC. If a coven member's departure or death brings the coven below three members, the remaining members keep their elite adjustments for 24 hours, but without enough members to contribute the necessary actions, they can't cast coven spells.

The sea hag can make a bargain with a willing creature who must be of sound mind. The creature gives away a special or cherished quality—such as its courage, its beauty, or its voice. In exchange, the sea hag spends 1 minute polymorphing the creature into a form the target desires. This functions as Change Shape. It might be a total transformation or just changing one or more aspects of the target's body, and it can't make the creature more than one size smaller or larger. The creature changes its Speeds as appropriate for the new form. It doesn't change the attack and damage bonuses with its Strikes, but it might change the damage type the Strikes deal. This has an unlimited duration, and as long as it's transformed, the creature is Sickened 2 and can't reduce its sickened condition below 2. The creature can slowly and carefully eat and drink despite being sickened. The only way to restore the lost quality used as payment is to defeat the sea hag or make another bargain for its return. Ending the bargain in this way also removes the transformation.

The hag gazes upon a creature, afflicting it with a gnawing sense of impending doom, with a result depending on its DC 20 will save. The target doesn't need to be able to see the sea hag. Critical Success The creature is unaffected. Success The creature is Frightened 1. Failure The creature is frightened 1 and is Slowed 1 for 1 round. If the target was Dying, it remains Unconscious for 1 day. At the end of the day, it must attempt a DC 20 fortitude save against the same DC; if it fails, it dies. Critical Failure As failure, but the creature is Frightened 2 and slowed 1 for 1 minute.
