Aggressiveness

Aggressiveness (or hostility) refers to the behaviour in RuneScape Classic in which some monsters will attack players automatically if they come within a certain range. This heeds players more in RuneScape Classic than in RuneScape 2, due to the combat system in RuneScape Classic preventing players from retreating for the first 3 rounds of combat. Aggressive monsters will also usually follow a retreating player for a certain distance.

However, with most aggressive monsters, if a player reaches a combat level that is one more than twice the monster's level, it will not be aggressive to that player any more. This rule does not apply inside the wilderness.

In RuneScape 2, there is a rule wherein monsters which are normally aggressive will stop being aggressive after a player has been in their vicinity for a set time. This rule is not present in RuneScape Classic. This makes AFK training more viable.

On this wiki, monsters are described using 5 levels of hostility:
