I Can't Find the Pain Taster

[Thunderforge]

So I was going to add the Pain Taster prestige class to my Hero Lab and when I went to create the new class it prompted me to select an existing class to use as a model and I found the Pain Taster in the list (and it wasn't grayed out). After seeing this I went back into Hero Lab, but there is no Pain Taster on the class list anywhere. I have the filter set to Everything, but still no luck. I looked in the purchaseable packages as well and saw no reference to Pain Taster or Armageddon Echo.

So where can I find the Pain Taster in Hero Lab?


EDIT: 5 more minutes of searching and I wouldn't have posted. Turns out it is Chapter 3 of Second Darkness.
