Aggressive

Aggressiveness or aggression, commonly referred to as aggro, is a trait in active monsters that determines attitude towards players in their vicinity. Aggressive monsters will target players nearby on their own to initiate combat and are indicated by a red name.

Only one aggressive monster will initiate combat at a time. If another player initiates combat with the agressive monster before it can engage its target, another monster will instantly target the player.

If the targeted player initiates combat with another monster than the one about to attack them, they will override the initial monster's aggression and initiate combat with the monster of their choice.

Non-aggressive monsters may be classified into active and passive monsters, depending on whether or not the player needs to be online to continue fighting them.
