Triage

Issue linked from CC: chromiecraft/chromiecraft#8137

Triage Notes:

.tele magisters
Enter instance, proceed to affected room (Room before the 5 boss/'PvP' fight)
Kill pack closest to door on left side
Kill patrol
Pull pack on right
Chain pulls pack at back right

I cannot recreate the middle pack pulling the back right pack, though I have seen this happen in some MGT groups on CC main server.

Recreated in CC PTR and on local AC

Apathyxia has attempted a fix here #22440

Current Behaviour

As of 10/7/25, there appears to be a new behavior regarding social aggro in Magister's Terrace which is causing multiple unavoidable pulls. In the room before the fight with Priestess Delrissa, the groups on the right side will social aggro in a chain, regardless of which npc is pulled, until all three groups have pulled at once. See image. Attempts to pull a single target from Group 1 or Group 2 results in the rest of the group pulling as expected. However, it also leads to the nearest target in Group 3 to social aggro. That in turn pulls the rest of Group 3, and will also pull Group 1 or 2 (whichever wasn't included in the original target's pull).

Pulling the initial target from different angles does not make a difference, as it is a social aggro chain caused by the initial pull action. Same results for different targets as well.

This seems to happen on the left side as well, to an extent, but only when pulling a particular target from the leftmost group (group is out of frame on the image above).

Expected Blizzlike Behaviour

Barring any bizarre behavior (such as pulling one group across another or at odd angles), social aggro should only bring a single group and certainly not all 3.

Source

It's not a great video, as they're trying to skip left side, but here you can see Group 1 pulling without social to Group 2 or 3.

Steps to reproduce the problem

1. Enter Magister's Terrace

2. Proceed through the dungeon past the Halls of Theory

3. Pull the first group in the room. Kill this group. This is not one of the three groups from the image.

4. Pull a target from Group 1 or Group 2. Social aggro will chain pull all three right side groups.

Just to clarify. The linked PR is what causes this exact issue. The PR itself created formations as most of the packs were pullable one by one. It is noted in the PR that the behaviour in this report happens, but I was not able to resolve it in a nice manner.
