Raise Zombie is a Novice level conjurationspell in The Elder Scrolls V: Skyrim that reanimates a weak dead enemy to fight as an ally. This reanimation is not limited to humans alone; creatures such as a dead bear, wolf, etc., may also be reanimated, as long as it is of a low enough level. This spell also works on intact undead that are not fallen enemies and dead creatures or characters that may be encountered. The spell will not work on headless undead or creatures that are not intact.
Characters reanimated with this spell collapse into ash piles after being killed again or when the spell duration ends.
The spell does not appear to work on Dragons, though no message about the spell "not being strong enough" is provided. From this it can be inferred that dragons cannot be reanimated.
Tip: When reanimating a humanoid that is a melee character, a helpful tactic is to place a rather strong melee weapon into its inventory (if one isn't already there) to increase the damage it may cause. The weapon is retrievable from the pile of ash after the spell has ended.
It seems that the Conjuration skill is trained not by the casting of this spell, but by actions done by the raised zombie.
