The Dark Creations spell allows the user to make anything out of darkness, like a large hand, a giant, a wall, etc. But the spell's weakness is light. If the user is in the light the spell won't work and if the creation is hit by light, it will melt back into the shadows. But if the user is more trained with the spell, the effects of the light won't have the effect anymore.
