However, you are never guaranteed to get any specific spell that you want.Īdditionally, starting research is randomized. Thus, you won't see the Warlord's Global Assault spell showing up until you've researched a substantial chunk of the Warlord's global spell list. It may be broken down a bit further (guaranteed at least X class upgrades and Y specialization/avatar upgrades), but I'm not 100% on that mechanic.įor a research of a higher tier to show up, you need a certain number of lower tier research of that type. The seafaring/casting point/class unit research lines will always be the same.įrom there, you have 3 empire upgrades to choose from, 3 combat spells to choose from, and 3 strategic spells to choose from.

Research trees are randomized to a degree. There's a thread over on the official forums that explains this pretty well.

Are you sure? I can't say about all the spells, but they seem to follow through the same tiers every time, at least I am certain about summoning spells doing this.
