Threat

The level of 'threat' (also referred to as aggro) that a monster has is usually (in MMORPG terms) a list, organised in descending order, that tracks the players currently in combat with it. The [monster will usually attack the player that is at the top of the threat meter i.e. the player that poses the most 'threat' to the monster.

• Damaging and healing done usually increases your character's threat value with the monster.
• Tank classes usually aim to generate the most threat and keep the monster hitting him or her.
• Nuking a monster that is untanked will often put the nuker at the top of the threat list.
