Aggressive mob
Definition
Aggressive mobs are mobs that attack you immediately after becoming aware of your presence. In most cases, this is right when you enter a room, but it can also occur after some sort of trigger, such as waking the mob up or drawing its attention. In some scenarios, an aggressive mob may not be aware of your presence because you are hidden or invis and it has no means of detecting you (i.e. detect invis or detect hidden).
Examples
It is safe to assume that most mobs that you run across inside a dungeon or other dangerous location will be aggressive. Many big run mobs are aggressive, such as Legba.
