Ward cumulativity

[jeffr]

Well, there goes my idea of making some of my troops immune to Wrathful Skies. I was going to use Thunder Ward plus Gaia's Blessing. Once Wrathful Skies showed up, my armies became (almost) useless, which is a shame. Making my leaders immune to lightning is easy enough, but I want to move armies around and not just leaders.

I think Gaia's Blessing is so expensive in terms of research level, casting level, fatigue and gems that it ought to stack with other resistances. As it is now, is it really worth it to cast?

Also, I noticed that Gaia's blessing does not stack with the Robe of Calius the Druid. Should it? Does anyone know if it stacks with Elemental Armor?
