Raise zombies is a technique added in SLASH'EM for the necromancer role. It will attempt to revive all corpses in adjacent squares and turn them into an appropriate zombies. Kobold, gnome, elven, human, ettin, and giant corpses will result in the corresponding zombie type. Goblin corpses will result in orc zombies. Other humanoids will become a ghoul 3/4th of the time or a ghast the remaining 1/4th. There is no effect on non-humanoid corpses.
An attempt will be made to tame the resulting undead with the same chances as casting charm monster. The undead will always be hostile if not tamed. You will be unable to move for 2 turns even if there was no effect, and the technique will be usable again after 1000-1500 turns.
