Mind your area

All too often, you'll find a monster straying into an area it shouldn't be.
For example, Thieves right outside town, hitting you for four times your
maximum HP. Or the level 16 Bandits wandering about while you're trying to
focus on that several hours long operational map quest. The areas monsters
roam about are very large. If you find that monsters that shouldn't be where
you are are showing up, you should run back for a good fifteen seconds or more.
