Stardust (Sp)
Source: Advanced Class Guide, p. 41
As a standard action, the shaman causes stardust to materialize around one creature within 30 feet. This stardust causes the target to shed light as a candle, preventing it from gaining any benefit from concealment or invisibility. The creature takes a –1 penalty on attack rolls and sight-based Perception checks. This penalty on attack rolls and Perception checks increases by 1 at 4th level and every 4 levels thereafter, to a maximum of –6 at 20th level. This effect lasts for a number of rounds equal to 1/2 the shaman’s level (minimum 1). Sightless creatures cannot be affected by this ability. The shaman can use this ability a number of times per day equal to 3 + her Charisma modifier. Greater Spirit Ability: A shaman who chooses the heavens spirit as her spirit or wandering spirit gains the following ability upon having access to the greater version of that spirit.
