We get a deeper dive on some of the Necromancer's skills especially the "Book of Dead" which seems to be its summoning skills. We learn there are three skills shown off including Skeletal Warriors, Skeletal Mages, and Golem. This information below is subject to change as this is not a final build but here is what we saw from the gameplay regarding the 3 various summons.
