I was bored last night and I thought What IF? What if I put an Exorcist into a 500pt list, will I be able to put enough units in to balance it. Well here's the list that I came up with, let me know what you think.

Inq Lord= 171
power weapon, word of the emperor
Alcoyte= power armour

Eversor Assassin= 95

2x 5 IST= 100

Exorcist= 135

Lack of speed for the troops is acknowledged but that was made so, so that my HQ could get to battle quicker and the ability to throw in a big gun.
