How do you add spells to a map?

My friend and I are playing on the "The Empire" map. Unfortunately, the map was created for version 2.1, which means it features the "Hammers of Fate" faction. There are no features that appeared in "Tribes of the East." I've made some minor edits to the map, adding various elements from "Tribes of the East," such as a mentor and an astrologer. However, is it possible to add spells from "Tribes of the East," and if so, how? (For example, Vampirism). Please answer.
