You tap into dark fey power, transforming yourself into a creature of shadow.

Minor Action      Personal

Effect: You transform into the form of a satyr of the night, and you remain in that form until the end of the encounter. While in this form, you have partial concealment, and when you would normally have partial concealment because of dim light, you are instead invisible. Additionally, you take only half damage from necrotic attacks.
