The hag blood coursing through changelings’ veins makes them especially adept at coven magic. Changeling witches with the coven hex can form covens of three changelings without the usual need for a hag member. But as a changeling draws upon the power of her heritage, the call to wander into her hag mother’s clutches becomes more persistent; changelings who form a coven only with other changelings take a –1 penalty on Will saving throws due to this increased stress.
Changeling witches with the coven hex who wish to form a coven must perform a 1-hour ritual. When the ritual is complete, the changeling coven gains access to the following spell-like abilities based on the witch level of their highest level participant.
1st Level: disguise other, fog cloud;
3rd Level: bestow curse;
5th Level: speak with dead;
7th Level: baleful polymorph;
9th Level: mirage arcana;
11th Level: forcecage;
13th Level: commune;
15th Level: control weather;
17th Level: vision;
19th Level: mind blank.
Coven spells use the caster level of the coven’s most powerful witch. They require each member of the coven to participate simultaneously, taking a full-round action or the spell’s normal casting time to cast, whichever is longer. A changeling coven can cast a total of three coven spells each day, regardless of the spell level.
In addition: all members of the coven are treated as if they possessed the same teamwork feats as all other members of the coven for the purpose of determining whether one of them receives a bonus from her teamwork feats. Her allies do not receive any bonuses from these feats unless they actually possess the feats themselves. The allies’ positioning and actions must still meet the prerequisites listed in the teamwork feat for any coven member to receive the listed bonus.
