While you have nothing personally against orcs, being sapient bipeds just like yourself, this one seems intent on cutting your head off with his scimitar.
You have three spells you could cast, a lightning rod you could use to launch a powerful lightning bolt at your enemy, and 10 magic points left in your arcane reserves.
Bear in mind that while Sleep is a very useful spell, it takes two hand to cast so you will need to drop your lightning rod and there won't be time to pick it up again.
