You are able to use your illusion powers more and they are more effective while located in the shadows.
Prerequisite(s): 6th-level shadowdancer
Benefit: You are able to use your shadow illusion class ability a number of times per day equal to your shadowdancer level instead of the normal amount. In addition, whenever you create an illusion spell which is located in an area of dim light, the DC of the Will save (if any) to resist the spell or recognize it as real is increased by 1 per 3 levels of shadowdancer you possess.
