Witchtooths are a sub-type of the Ogre seeming.
The embodiment of the cruel, man-eating hag and the selfish, mystical monster, the Witchtooth is among the wisest and most cunning of Ogres. The Witchtooth have a penchant for dark magic, particularly curses. While many of the most famous examples of this monster are female — Baba Yaga, Spearfinger, Black Annis — male changelings can learn the ugly secrets of Witchtooth wisdom as well.
Black Hex: the character may spend Glamour to increase Occult rolls, and gains a one-die bonus to activate any Contracts that involve cursing another person (such as Fickle Fate).
