Retreat

Retreating is the act of disengaging from combat. Both player characters and monsters with retreat hostility may back off during combat, but only after the first three rounds have occurred. Because of this game mechanics, it is often desirable in Player Killing to be able to kill your opponent in these first three rounds of combat before they are able to retreat. In the context of monster killing, it means that aggressive monsters are much more dangerous in RuneScape Classic than in RuneScape 2 as a player could potentially be killed before they have a chance to retreat.
