Shadow hand

Shadow hand was an illusion spell that would conjure a translucent, billowy hand that obeyed the will of the caster.

Effects
The shadowy hand had to stay within a number of yards of the caster, depending on their level. Although each action it took required the caster's command, it did not require continued concentration throughout the spell's duration. If the hand struck or otherwise touched a creature of the caster's choosing, it would slow them, although the damage caused by its attack was minimal and non-forceful.

It had no effect on the undead, golems, constructs, creatures from the outer planes, and primitive non-vertebrates (such as oozes, slimes, and non-intelligent plants).

History
This spell was created by the wizard named Jume several hundred years before the Time of Troubles and recorded in her personal spellbook, the Arcanabula of Jume.
