Aggrophobia

Anime Style Threat/Aggro Indicator

This addon shows four anime style "anger marks" -- indicating the highest threat you have from all NPCs you are considered in combat with -- ranging from lowest (1 mark) to highest (4 marks).

This addon also shows crossed swords indicating that you're in combat.

Option to show on-screen aggro/threat warnings such as threat level changes between you and NPCs, along with the level, name and classification (elite, rare elite, world boss) of the NPC.

Threat Levels

Marks - Description
1 - Low threat towards you [0, 100%).
2 - High threat towards you [100%].
3 - Tanking one or more NPCs. High threat (100%, +].
4 - Tanking one or more NPCs. Highest threat (100%, +].

It can take a moment before an NPC switches targets.

Technical

If you attack an NPC -- and it pulls other NPCs with it -- then the other NPCs won't necessarily be shown as having any threat towards you, even though they're heading towards you.

Some interactions may put you in combat without threat (crossed swords), like a quest that involves a tiny NPC digging through dirt in Stranglethorn Vale.

Some stealthed NPCs may put you in combat (crossed swords) without indicating any threat.

Some NPCs may be scripted to attack you regardless of threat level.
