All,
The SHM Malos line does not land on the General.
ENC Tash *does* land and so does Mem Blur and Lull.
Best to clear-out the house, inside and out first, leaving one DEF up.
(the roaming DEF Assassin has no part to play here so ignore him)
For a ROG, it is easy-peasy because of Sneak/Hide. However, for a BRD, it was difficult for me because I could not hide fast enough after handing-in the Sealed Box. So, I agroed both the DEF and General.
Through several trial/errors, the way I was able to do the turn-in by lulling the General and approach as close as possible, without agroing, for turning-in Stanos' head -- that is to say, turn-in the head at the furthest distance you can. This was at the Misty zone area. After handing the head over, the General poofs and the mask is in-inventory.
