Bosses

The so-called Tibia "Bosses" are unique in their own races. They are stronger than any of the creatures like them, and they are relatively rare to encounter.

Bosses do not spawn like normal creatures, they are only found in a world on rare occasions depending upon the abilities of the players in that world. If they are not killed in one day, then they disappear until another time.

Bosses are not restricted by the normal "anti-luring" boundaries, and they will not "poof" when they wander too far from their spawn point.
