To remove the Rogue abilities, you can add the following line of code to the Class thing at Render/10000:
Code:
~ Remove Cleric abilities from Corruption list
field[cCstS2Expr].text = "SpecSource.cHelpThg & Helper.Secondary"
Also, the custom ability names can be easily fixed on the same thing.
I've done both of these for the next release. Can someone please get me the text for the class description? This should also be included.
