wow, what a fight. Took about 35-45 minutes to complete, but myself and my friend did this with:
Valkyrie (mine is spec 50 spear, 42 shield, 30 odins, 22 mend, 12 parry, 6 sword)
Valkyrie (friend's is 50 sword, 42 shield, 35 mend)
Shaman bot (48 Aug, the rest cave)
Healer bot (30 mend, 35 pac, the rest aug and has power font)
some side notes... we weren't even templated fully, both Valks were only ML1, what I would recommend is to have the shaman bot be ML1 for group cure disease so that the healer can focus on spread heal. However we did RA respec to get Avoidance of Magic 3 (we originally tried Zilis a few days ago testing strategies and found the magic damage can add up a lot) the extra 10% helped, but a Hero/Warrior/armsman would be more ideal.
THE MAJOR THING YOU NEED!!!
1) SPREAD HEAL!!!
2) POWER FONT!!!
3) group cure disease
You need to set up power font below the ramp near the summoner hall entrance. Stay out of view of Zilis, but stay close enough for endurance, celerity and resist rebuffs for your tanks.
Zilis will drain all the power from anyone near her (within like 700 units or so) and use that to AE DD spirit damage lightning.
Zilis will phase in and out of physical form, when she is in ghosted form, her other 3 purple mobs will be physical and vice versa. (NOTE, it is a myth if you kill the 3 other bosses in PoC that she will not pop them, this is not true she will always spawn them)
OK HERE'S THE FIGHT------------------------------------------------------------
~ Buff up all your magic resists, damage add, damage shield, protect spread healer, valkyrie magic ablative helps a lot, use any defensive buffs you can such as SoM, ablatives, AF shields, spear of kings aura etc. and get ready to group cure disease and spread heal with your support.
~ KILL DREVAUL FIRST, he is the healer
~ Have 1 or 2 tanks focus on killing the plague fiends that spawn, they can sometimes add up. Also note, if you do not attack a fiend they will not cast/attack you. There have been times where 1 fiend ran to my healer or our shaman but it did nothing but stand in front of them since the healer/shaman did not attack the fiend.
~ Use any pet spam/call of a thousand arms on Drevaul/Rheton/Busiv souls. After Drevaul is down, hop over to either Rheton or Busiv (we did Rheton because he seems to be the one that AE diseases)
~ After all 3 souls are dead, get on Zilis. She is a beeyatch because she keeps going in and out of spirit form (not sure if this is intended after all 3 souls are dead....) I only killed her once, so I can't say for sure but she definitely does not seem to be level 65 as they claim here. She felt more like level 78-79. Do a ton of bleed styles on her when she is in physical form, slam/stun her in physical form and try and unload as much damage as you can on her then. She took us about 25 mins to bring down, just be patient.
~ side note... if you die on her, have a healer rez and usually she will still stay in combat for you to rebuff.
She is a challenge, but her drops I find are WORTH IT! All her weapons have a proc of a -20 melee ABS, 100 quality 16.5 dps weapons. Her bracer is fantastic for templates: +24 dex/con/qui/pie and 10 charges of 20% power replenish.
