There is a mod somewhere around the forum that converts those 2 units into spiders instead of sentinels. Do a search for Spiderworshipper and you could follow that example, this was a topic quite a while back but I tried it and it worked.

Hey

Thanks for the info.

Elemental is the first game I'm trying to make mods for, and one thing I learned is to close the XML editor when tired, there's just to many lines of info. That SovereignHistories.xml file was staring me right in the face.

I have not been able to replace the Sentinels, but I did give them each a tweaked Longbow and some Boots for increased movement.

Now I just have to figure how to make my custom buildings available to my custom faction only and not to all the other men races on the Map.
