I don't know anything about IG guides. But I do know how to change creature stats. In the data archive, you need the Vindicator.xdb file. The path is: data/GameMechanics/Creature/Creatures/Haven/Renegates/Vindicator.xdb. Open it with Notepad, find the line WeeklyGrowth 10 /WeeklyGrowth, and change 10 to the number of creatures you want. You also need to do this for the Swordsmen and Armored Knights.

And it's better not to change the date at all. Instead, you should create an archive with the path mentioned above and put it in the UserMODs folder.
