A troll's appetite and its regenerative powers make it a fearless combatant, ever prepared to charge headlong at the nearest living creature and attack with all of its fury. Only fire seems to cause a troll to hesitate, but even this mortal threat is not enough to stop a troll's advance. Those who commonly battle with trolls know to locate and burn any pieces after a fight, for even the smallest scrap of flesh can regrow a full-size troll given enough time. Fortunately, only the largest part of a troll regrows in this way.
