Have a bird aggro the two Elite alien lorekeepers out of the Overlord's room one at a time. Then kill them at the doorway without aggro-ing the OL

The best time to kill the Keeper is at first encounter. Focus all attack on the keeper and the AoE skills should kill lots of the aliens in the process. With that, you can kill the keeper or seriously cripple his health. Please note that a mage needs to Spam heal for the tanks and to be wary of his staff repulse.

Before opening any prisoner caskets, clear out all the aliens in the main hall. This'll prevent a shadow demon from wiping your team. Please note that opening them one at a time is REALLY helpful.

I'll have more coming
Alright! Thanks!
