Battle Tactics vs. Long Range Foes?
When fighting a group of NPCs, always try to stay out of the range of Shamans (Fireball) or Orc/Skeleton archers. If that is not possible, attack them directly. They need a few seconds to switch from long range to short range weapons, making them vulnerable. Especially when fighting at the side of a NPC (who is supposed to survive the battle), always attack the Shamans immediately, because their spells usually wipe out your side-kick.
