The shadow companions you can summon are more powerful and resilient.

Prerequisite(s): Cha 13, 3rd-level shadowdancer

Benefit: The shadows you summon with your summon shadow class feature gain the following improvements: an additional +4 bonus to Will saves made made to halve the damage from positive channeled energy; total hit points equal to three quarters of your total rather than half; and an additional +1 Strength damage per four shadowdancer levels you possess when it successfully damages a creature with its incorporeal touch. Additionally, if the shadow is destroyed or dismissed, you are able to replace it after 20 days rather than 30, as normal.
