I feel like glorious transmutation should act more like demonic anthem and be an on death effect as it makes effects like steadfast useless but maybe that intended?

I do think I want to change the ability, it's the last one I came up with and I don't super love it.

I ideally want all of the cult buildings to have produced units have a mostly positive, but also potentially negative, effect. Khorne gives berserker rage, which is usually positive, but can be negative.

I like the tzeentch effect, but don't love it. I'll be going back to the drawing board on it.
