Ice Hag often called Ice Crone

This is the default hag on my world, as icy conditions predominate. They are usually found in icy caves, found throughout the realm in virtually every location.

 SPECIAL ABILITIES

Charming Gaze (Ability Ex) Anytime a victim meets an ice hag’s gaze, they must resist their powerful trance. The will save is Will DC 18. (The save DC is Charisma based.) The hag must continually look at the victim to keep up the gaze, if the gaze is broken, so too is the powerful charming effect.

A frozen, withered crone looks at you and crackles, you know you are in deep shit.

Horrible creature found throughout the cold wastes of Nyssa, who seek to feed on the living and use the dead as zombies under their command. Hags prefer to attack lone travelers or small groups, when this is not possible, they use their ice manipulation to create scenarios to isolate individuals.

While hags live in communal cave lairs, they work together only for mutual defense. They sometimes share meals in good times, however treasure and magic are always kept hidden from the other covey members. Often one hag’s jealousy can lead to infighting. Once they have fed, an ice hag can easily be bribed with coin or magic.

Hags are similar to undead in that they are created by victims from other races. They trap victims in an icy pit, ice block or similar area, and after years of imprisonment, with both their minds and physical bodies decimated by ice - they emerge as new Ice Crones with a hunger for inflicting horror and carnage on others.

An ice hag uses their spells to weaken and separate groups before entering melee.  What many travelers in the ice often fail to reckon is the horrible, twisted crone they sometimes must face in the wild, can be a sweet, even kind elderly folk that they know. It is not a different personality but a split spirit, in some ways, something like a lycanthrope.
