Twilight Acolyte Katrina: Not even Katrina Prestor was immune to the enticing influence of the Twilight's Hammer Cult. Seeking to bring a Cataclysmic end to the world, she will don the robes familiar to all acolytes to enact her plans. Katrina's new appearance will be a call to the cultists in World of Warcraft, wearing a dark purple and black robe accompanied by hood with ornate markings on the cloth. The staff she wields now will contain a black crystal at the tip of it that radiates shadow magic, perfect for the master manipulator that she is.

3. Nefarious Twilight Acolyte Katrina

v0.10: Created concept, put in basis of abilities, talents, and stats. All are likely to be subject to change. Added quotes and PH Concept Ideas.

v1.1: Increased Empowered Manipulation to 25% damage (up from the unwritten amount of 15%). Specified health percentages for Break Illusion and Empowered Break Illusion. Changed the health on the whelps in Whelpings to be killed by any two basic attacks from any source.
