Forlorn Spirit (banshee)

The Forlorn Spirit appears a few times throughout The Legend of Stalvan quest chain.

There is a delay when she first appears before she attacks in which you should be able to run away if you do not want to confront her.

Oddly, she has a aura, even during combat (noted during Moonbrook encounter.)

Abilities

 * Curse of Stalvan: Reduces all of an enemy's attributes by 5 for 10 min.
 * Polymorph: Transforms the enemy into a sheep, forcing it to wander around for up to 20 sec.

Identity
She may be Tilloa, haunting places where her murder Stalvan Mistmantle left personal things.
