This encounter can spawn Brixx, Borxx, Braxx if done wrong.
It is best to split tank this encounter.
On the pull, the MT should agro the guardians, and then single taunt Pkzwk when he's in range. At the same time, the secondary tank should Rescue pull Overlord Oxulius and drag him away from the rest of the encounter.
All DPS should be concentrating on Oxulius first and make sure he goes down. If he drops a chest, you MUST LOOT the chest before killing Pkzwk or you will get BBB. If Pkzwk dies before Ox, BBB will spawn.
Guardians will continue to spawn as Pkzwk calls for help, but they dont do too much damage. Once Ox is dead, everyone must focus on Pkzwk. If the linked encounter adds are killed before him, BBB spawn.
So do not allow AE's until both named are dead.
Ox has a chance to charm, and his nukes are magic/mental based, so be sure to have a good resist for this.
