As you may know, every class has a Soulforce or level based skill when Morai was released. Along with that level 80 Morai skill it could be further upgraded by the level 100 AEU skillbooks. Clerics got Violet Dance which upgraded into Ultraviolet Dance, Barbs got Berserker's Rage which upgraded into Berserker's Wrath, BM's Sword Cyclone upgrades into Sword Tornado, etc.
Will Nightshades ever get the same thing as the previous classes? As far as I know, there are only Apocalypse Page skillbooks, 3750 prestige skillbooks and Chrono Page skillbooks. The next expansion includes Primal skillbooks which are indeed great but did PWCN accidentally skip over AEU skillbooks in general or was it on purpose?
