Thanatocraft

This spell is a minor magical trick that novice necromancers use for practice. You target one corpse or skeleton within range and produce one of the following magical effects:

• You cause the joints in the corpse to move, such as a twitching foot, a grasping hand, or a tilting head. This effect cannot be used to deal damage or activate magic items.
• You cause the corpse's facial muscles (if it has any) to move, such as an eyelid flicking open, a mouth stretching into a smile, or a tongue sticking out.
• You cause organic matter within a 5-foot cube to decay, such as flowers wilting or meat spoiling. This effect cannot damage creatures.
• You create an instantaneous, harmless sensory effect, such as a flickering flame, a dimming light, or the scent of decay and rot.
• You cause the corpse to utter a message no longer than 5 words. If the corpse has a mouth or jawbone, you can choose to make it seem as if the message were coming from the corpse's mouth.

If you cast this spell multiple times, you can have up to three of its non-instantaneous effects active at a time, and you can dismiss such an effect as an action.
