You target a minimum of 5 --to a maximum of 10-- skeletons or zombies under your control (must be one or the other) within range and magically bind them together to form a horde of undead. You may have no more than two existing undead hordes at a time, attempting to bind a third together will cause the last bound horde to unfurl.
The horde is under your control for 24 hours, after which it stops obeying any command you've given it. To maintain control of the horde for another 24 hours, you must cast this spell on the horde again before the current 24-hour period ends.
