Running away from Foes?
It is typical for RPGs that foes have a limited tenacity when it comes to following the player. You can use that to your advantage: Get close to an Orc, until he follows you, then clobber him a bit away from the rest of the camp, and then repeat this method. Note that other Orcs in the camp will at some point give up the chase if they are far enough away. In an emergency, with the odds very much in favor of the Orcs, you can simply sprint away from the camp to safety. This is possible, because the player is faster than any foe or animal when sprinting.
