Well, i've seen many pugs failing this raid because of a lack of knowledge in tanking the last boss. It's pretty easy and i would like any basic tank to be able to do it so that you don't need to ask for a tank and wait for him everytime you want to pug it.
I'll assume that the tank doesn't have evasion, or a dirty one. I wouldn't advise to rely on it to avoid the firebreath.
Only thing to make sure is that you are not laggy, if you are, avoid tanking this one.
Buffs needed : Basic buffs + FOM + Protection from evil + Deathward
As you all know it, or almost, the Conjoined Abishai Devastator has 5 forms : Red, Blue, White, Black and Green. Each corresponds to an element. The effects i'll explain below are basically applying when the boss is "dragonning" (when he has a kind a dragon ghost around him).
What to expect from each form (easiest to hardest in my opinion) :
- Green : Does he fart ? Only thing you can fear from him is casting fog. Nothing really dangerous. Just avoid having too much fogs on the screen : risk of lag and/or kind of blindness. It's easily dispelable.
On this form use ELECTRIC WEAPONS, avoid ACID WEAPONS.
- Black : Well, just expect this one to cast curse on you. When he is dragonning he casts a first curse all around him, and another one when finihsing dragonning. Just be ready to use pots to let casters heal you.
On this form use ELECTRIC WEAPONS, avoid ACID WEAPONS (not sure on this one).
- Blue : The electric form. When he is dragonning he creates a ligthining storm. With the white form he has the longest dragonning time. Expect like 10-15 seconds of lightning storm. If you are tanking stay away from him, or you'll certainly die. For the dps on his back, i'd advise to stay away for 2 reasons. First you may get hit by the lightning storm, and die, second, if you are hitting the boss while the tank isn't, well you may get aggro. Depends on your tank really, if he is heavy dps you can keep hitting.
On this form use ACID WEAPONS (not sure), avoid ELECTRIC WEAPONS
- White : this form can be especially tuff if the party isn't listening to orders and not aware of what to expect in here. When dragonning everyone must STAY AWAY FROM CRYSTALS ! If a crystal explodes on you : you die. It's annoying when you see half of the party wiping because the kept dpsing... Well the area the most touched by crystals is just in front of the boss, so, just where you tank it. So just stay away. FOM is a must have here cause the area got covered with ice.
On this form use FIRE WEAPONS, avoid ICE WEAPONS (obviously...)
- Red : AAAAAH the sooo feared firebreath ! Nothing really difficult here, since you are not laggy. As soon as you see he starts dragonning JUMP IN FRONT OF YOU OVER ITS HEAD, and just wait for him to breath. Most important is to make sure the boss isn't going to face the whole party, because i can't figure a full party avoiding the breath. If you fail your jump (it happens : tripped, laggy, piking ^^ ? ...) then just let someone who has aggro keep the boss not facing the party. Dying there happen. Even perfect tanking can't avoid a trip at the bad moment, or a lag. Make sure other guys in the party know what to do if this happen. If you are an evasion tank and are willing to rely on your evasion, well, you can. I know some doing it very well.
On this form use ICE WEAPONS, avoid FIRE WEAPONS (again obviously)
I hope this will help out some people doing this raid fearing the last boss. As i like to say it, in a raid, the secret is that everyone need to know what is going on. Take your time to explain everything to your party before you go, and that everyone understand it.
I may do some runs on elite to show some people how to do it, though with this guide you should be able to understand what i mean, unless you've never been there.
I wish you good luck on your future chronoscope runs, and meet ya ingame !

Mr Armoraarrhs aka Gilleane also told me : " if the tank doesnt have evasion and his Mario skills are not good nuff or he he's laggy but NOBODY else can tank in the group, then must-have are: cloak of ice and firestorm greaves or greenstell fire absorb weapon. What I'm actually using all the time. Every time he goes red from, I put cloak of ice and use clickie"
