i've played in that tomb so much, so heres some knowledge
Suitor Spirits :
good prey for drops, list of some i have had from them below. Watch out, will sometimes (becomes always when in groups or higher level) baf if there is more than one. i have never had more than 2 at once though.
drops
Marvelous Cloak (1) Bloodstone Studded Falcata? (3ish) Various Armours A Large Weapon (forgotten name) Celtic Spear (forgotten name) Piercer (forgotten name) Belt of the Deranged (3ish)
These make for very nice pulls, they don't BAF or call for help as far as I know. I'll have to do some hunting when I get home, see what drops I can get. I believe these are found in the room before Kacey Muire and her Muire-Lady-In-Waiting's.
