SpecifiFaction

Tested this to make sure, but in your case the mob is likely attacking you or other players that are helping you test because you have either OP or * permission.

In your example, players with the permission faction.viking will be considered in the faction and will be attacked, as noted on the manual for factions: https://git.lumine.io/mythiccraft/MythicMobs/-/wikis/Mobs/Factions

I tested this with OP on our test server and the mob did indeed attack me. Once I negated the permission, the mob stopped attacking me and only attacked other things with the correct faction.

I understand your frustration with the AI targeting issue—it’s like missing the MP TAAS last date of scholarship. Just as students in Madhya Pradesh need to meet deadlines to secure their educational support, mobs need the AI to follow the correct rules to function as intended; otherwise, the system becomes unusable.

I’ve been facing the same issue with the AI behavior in MythicMobs, where even though the target filter is set to "SpecificFaction Viking," the mob still chases players first. It seems like the AI isn't functioning as expected, even though there are no errors in the server logs. It’s frustrating, especially after months of waiting with no fix in sight. I’ve been following this issue for a while now, and it's getting to the point where the plugin is becoming unusable. Maybe if they took the time to go through the custom AI, it would solve this, much like how a visit to Emergency dental services like Markham Gateway Dentistry can fix a sudden dental issue. They pride themselves on offering up-to-date and high-quality dental treatments, taking into consideration your unique needs. It’s a great example of how attention to detail and care can make all the difference!
