Necrolord Assault

If you're stuck on the Necrolord Assault and 'seem' to have completed all the quests:

1. 
   
2. After completing 1/1 Report to Draka at the gates of Perdition Hold;
3. 
   
4. Only have 3/4 of Help Maldraxxi forces assault Perdition Hold and are now clueless. NOW GO TO MIKANIKOS (37, 63.4)... he will give you a quest to retrieve 5 Anima containers inside the Hold.
5. 
   
6. Collect them quick, turn the quest back into Mikanikos, then you need to go back into the Hold to the Battleready Centurion (32.5, 68) and click on him. He will slowly lead you forward and help kill a bunch of NPCs. When finished you NOW HAVE 4/4 of Help Maldraxxi forces assault Perdition Hold.
7. 
   
8. Now you can go to Draka and use the Battlehorn which should pop up. Sheesh. Continue from there.
9. 
   
10. Run ahead and Kill Vexicon, Evelana the Dredd, and Ritualist Asmea, shown on map (click on Draka's Battlehorn again for each encounter to summon troops to help)
11. 
    
12. TA DA! You get War Chest of the Undying Army containing 250 Stygia, 50 Soul Cinders, and a Ripped Cosmology Chart (3), for 300 Cataloged Research, plus low chances for iLvL 200 gear and a mount, etc.
13. 
    
14. After all that, the Tormentor of Torghast (~ 1200K health) will be up outside; form a custom group as a raid with around 8-10 ppl and down him for more goodies.
15. 
    
16. Get more coffee or herb or something and finally chill for a bit. This assault sucks.
17. 
    

My God, what a mess of a world quest. I can't turn in the Centurion parts, the companions disappear half the time, rending roar lasts surprisingly long and does a great deal of damage (God help you if you get more than one stack) and the stupid blob doesn't recognize my kills half the time if I kill at range. Stupid, stupid, stupid. I'm skipping this one.

Draka's Battle Horn shows up on your screen as a clickie when you get close to her @ 31, 59. She is on a round platform by a very large crossbow thing.
