For a list of aggressive monsters, see Category:Aggressive monsters.

Aggressive monsters will initiate combat with a player on their own.

Aggressiveness is a trait in monsters that determines attitude towards players in their vicinity. Aggressive monsters will target players nearby on their own to initiate combat. Only one aggressive monster will initiate combat at a time. For some entities, aggressiveness is negated after a certain period of time, by being a high enough combat level, or by wearing a certain item or set; for others, aggressiveness can never be negated. A monster that is not aggressive is tolerant.


Most monsters will keep their focus on a single player; however, some monsters have an aggression that regularly refreshes, targeting different players each time. Examples of monsters which do this are vitali and the Corporeal Beast.

Monsters that become tolerant

Over time

NPC tolerance

Over time, most monsters become docile.

Over time, almost every aggressive monster can become tolerant of a player. This docility usually happens after 5-10 minutes of staying in the vicinity of the monsters. Monsters that have already spawned and targeted a player do not become docile, but newly spawned monsters will not be aggressive. Docility will only reset if the player moves too far out of their tolerance range.

With level

Monsters will not be aggressive to players who are double that monster's combat level. For example, a level 51 moss giant will not be aggressive towards players who are combat level 102 and higher. As the maximum combat level that players can achieve is 138, aggressive monsters level 70 or greater will always be aggressive to players.

With items
