Gwyllion

They are ugly female spirits that are usually described as wearing ash colored clothing with an oblong four-pointed hat, and usually carrying a pot of boiling poison in one hand. They also are known by their disturbing laughter. They live in mountainous areas and love to mislead and murder travellers. However, if a Gwyllion in disguise enters your home and is treated right, they will do no harm. The Gwyllion is repelled by metal knives, and a flash of a knife is usually enough to send a Gwyllion away.

Gwyllion are hideous lesser hags. They attack travelers, or else lead them to dangerous stretches of the mountain they call home. Gwyllion love the suffering of humans, but are friends to the mountain goats, and sometimes take the shape of such an animal.

Combat

Gwyllion do not like an open fight. They will attempt to ambush an opponent significantly weaker than they are, but otherwise would prefer to trick travelers into a pit trap or other hazard In their natural form, it does not take much for a Gwyllion to be mistaken for an old and bent human woman, but her red eyes and claw-like nails give her away on close inspection.

Alternate Form A Gwyllion may choose to take the form of a mountain goat at any time. Shifting between forms is a move equivalent action that provokes attacks of opportunity. In goat form, the Gwyllion has its own mental stats, but is otherwise like any normal mountain goat.
