At the third Turek Orc encampment, if you round up a bunch of mobs as a Wizard you can use your arrow keys to run through the center of the double wooden barrier. Once to the other side, you can flame strike them without the fear of getting hit, because the path finding won't allow the orcs to go beyond the barrier.

This is also effective as a dwarf with a polearm, as the length of the pole arm can allow you to strike the Turek Orcs from the side of the barrier without them hitting you.
