Beldam

This wooden monstrosity stands like a tree grown into the shape of an immense crone. She taps behind herself with a heavy wooden tail, and eyes like glass orbs are set into its gnarled face. The spindly creature stands twice as tall as a man, creaking with deliberate and uncanny movement.

Taken from the Creature Codex

No creature represents the decay of reality as strongly as a beldam. These bizarre intelligent plants native to the Plane of Shadows are obsessed with consuming lives and “season” their victims by trapping them in a web of illusions specifically tailored to each victim. As the poor soul slowly realizes that their fantasyland is not what it seems, the beldam often engages in rigged contests and games designed to drive their victims into an even deeper sense of despair. Once the beldam is revealed for what it truly is, it consumes the life-force of its victim and transforms it into a literal shadow of itself to join the beldam’s “family”.

Beldams do not associate with others of their kind but do gather to their sides all manner of horrible monsters to serve it. Some of these creatures have foolishly entered bargains with the beldam and serve to avoid being killed and eaten, but others are poor souls that prefer the beldam’s world of fantasy to the harshness of reality. Every hundred years or so, a beldam is driven to reproduce and plants a seed in some remote location. For fifty years, the juvenile beldam is merely a tree, albeit one that bears an uncomfortable resemblance to the human form, until it uproots itself in order to spread chaos and misery.

A beldam stands fifteen feet tall and weighs 800 pounds. They are seemingly immortal and are only able to be killed by violence.

Special Abilities

• Create Spawn (Su) Any creature killed by a beldam rises as a full-powered greater shadow 1d4 rounds after it is slain. A beldam can control any number of greater shadows.
• Decaying Veil (Sp) This ability functions as veil, except that every hour that passes, the  disguise grows thinner, granting all effected creatures a -1 penalty to Disguise checks until the bonus reaches +0. When this occurs, the spell ends. This is the equivalent of a 5th level spell.
• Powerful Tail (Ex) A beldam’s applies 1.5 times its Strength bonus to its tail slap damage.
• Shadow Blend (Su) In any light conditions except for direct sunlight, a beldam gains full concealment (50% miss chance).
• Uncanny Mind (Ex) A beldam gains skill ranks and class skills as if it were a creature of the fey type.
