Welcome to Librarium Online!
In the last edition there was a faq on sacred spawnings. For 20 points a unit you could add +1 armor save, +1 magic resistance, but the whole army had to take it. What happened to this? It added a really nice lore side to it as you could have a unit of extra tough sarurs or super armor templeguard. It also meant you could have a great army color scheme. If it's gone I hope they add it back. I wanted to add extra bony bumps on the sarus's to add the +1 save.
That was in the 6th edition lizardmen book. Died when the new lizardmen book came out last febuary. Since our book is relatively new, it will be years before we get another update probably.
I am right 94% of the time, why worry about the other 3%.
