The Necromancy spell, "Spell of Awakening" is a bit kooky. When an enemy hero dies, you may turn it into a Zombie Henchman that may retain its weapons/armor, though you forfeit the ability to use equipment or skills. Now, for reanimating humans, this is pretty cut and dry, but for other zombie types, the results might get a little interesting.
-Can a Zombie retain any special rules that are not technically Skills? For example, an Eshin Assassin with Perfect Killer, a Sisters of Sigmar Augur getting rerolls, or a Dwarf with Hard To Kill?
-Can a Zombie retain any Mutations/Possession results/etc?
-Can a previously-undead hero become a Zombie in this manner? For example, could one theoretically raise a Zombie Vampire or something similar?
