Dark Sister

At 2nd level, a Dark Sister can insert negative emotions into the mind of a single target. She gains a +2 bonus on Diplomacy and Bluff checks to sow suspicion, hatred, or other forms of animosity. In addition, a Dark Sister can choose to increase the save DC of any spell with the fear descriptor she casts by 2. She can increase a spell's DC in this way a number of times per day equal to 1/2 her witch level. This ability replaces the witch's 2nd-level hex.

At 8th level, a Dark Sister can violently dismiss her curses to counter magical boons and impose her own capricious whims. Once per day, after the Dark Sister has successfully affected a creature within 30 feet with a mind-affecting spell, spell-like ability, or hex with a duration of longer than 1 round, she can choose to dismiss the mind-affecting effect as an immediate action. If she dismisses this effect in response to another creature targeting her victim with a beneficial spell or ability, the witch's effect is dismissed and the caster of the beneficial spell or ability must succeed at a Will save (DC = 10 + 1/2 the witch's level + her Intelligence modifier) or the spell or ability is wasted to no effect and the targeted victim takes 1d4 points of Wisdom damage. At 14th and 20th levels, a Dark Sister can use this ability an additional time per day. This ability replaces the witch's 8th-level hex.

At 12th level, a Dark Sister gains a blessing in the form of an alliance with a night hag. Once per week, the Dark Sister can as a full-round action summon the night hag from the Shadow Plane. The night hag serves the Dark Sister to the best of its ability as long as the witch's commands are consistent with the night hag's alignment and goals, but flees back to its native plane after a number of rounds equal to the witch's level or upon losing half or more of its hit points. The night hag may provide the Dark Sister with other favors or gifts at the GM's discretion. At 15th and 18th levels, a Dark Sister can call upon her hag crony an additional time per week. This ability replaces the witch's 12th-level hex.
