The first thing you need to know about this event is that if ANYONE DIES it will spawn "a spirit wraith" for each person that dies. (think uqua) The wraiths stay up for about 60 seconds and hit for around 1600 (if i remember correctly) and knockback hard. This means that you MUST NOT bring people into this event who are not prepared to focus on the fight. EVERYONE must be doing their jobs on this or YOU WILL FAIL. Some may think this is an exaggeration, but i have seen a single Linkdeath wipe a raid, so take caution in this fight. This also means that you need warriors who can take vishimtars hits. (around 4-5k each)
Positioning is very important in this fight. There is a large wall in the middle of the arena with a giant stack of boulders and a hole in the wall behind them. We position vishimtar to the left of those boulders and have the MT corner himself between them and the wall. Have Melee slam him against that wall. (if you put him to the right of those boulders you can push him through the hole and you do not want that )
Vishimtar AE Rampages, tho not very badly.... it is much like yar lirs ramp, kinda neglegable, but enough to keep your healers and casters away from him. He also casts:
Spell Info: Vishimtar's Shadow PB AE 2000', Chromatic (-500)
1: Decrease HP when cast by 1250
2: Decrease Hitpoints by 850 per tick
4: Decrease Movement by 5%
11: Decrease Mana by 5 per tick
When Vishimtar reaches approximately 75% ( i say approximately because it is never the same each time except for the cloud of concentrated chaos) he will start spawning "a tainted egg" in one of 6 places around the arena. (far north, north, in-camp north, in-camp south, south, far south) -- The eggs must be killed within approximately 40 seconds or so (never really timed it) or it spawns "a corrupted drakeling" which will rape the raid. You MUST use blunt weapons. no spells, no procs, no dots, nothing but BLUNT weapons will damage the eggs. (the good news is blunt does a LOT of damage) Eggs will spawn until Vishimtar dies.
Also, at approximately 75% health, vish starts spawning "Incorporeal shadows" which will immediately charge the raid...... DO NOT KILL THESE EVER. they have VERY LOW HP (less than 1000) and even accidental ripostes will kill them very easily. The good news: They dont hit hard at all.
The bad news: They knockback and are not snareable or mezable. IF They die they spawn a LIFEDRAIN SHADOW-- this is VERY hard to recover from, but it can be done. You can offtank or mez the lifedrain. It will eventually depop but while it is up it will hit for 1500s or so. Once lifedrains are no longer in play, vish will spawn another incorporeal shadow. (this means you cant get rid of them, you just have to deal with them.) The way we handle them is we have knights unequip weapons and kite them the whole time.
Now, there should also be "a cloud of concentraded chaos" up also. at this point you should DPS it down to 15% health and mez it, do not mem blur it, or it will regen. Save this for later. (when it dies it casts an ae on the raid that gives full mana/hp.)
At 50% health on vish, he spawns another cloud of concentraded chaos and activates 4 Corrupted Drakes in the 4 corners of his arena. They hit for 800s or so and have a HUGE aggro radius and hit box. The way we deal with them is have paladins offtank them, without damageing them. 2 paladins should be able to hold 2 each, so have rangers drag them to the paladins. Get them debuffed and slowed and have healers on each pally. keep them locked like this and you should not have much issue with the drakes.
When vishimtar reaches 30%, you should kill the cloud of concentrated chaos that spawned at 50%, leave the one that you dpsed earlier alone for now.
Now the killer--- when vish reaches 25%, he spawns 4 "mournful spirits" around the edge of the arena. 45 seconds after that (approximately) he begins to cast:
Spell Info: Creeping Doom Single Target, Unresistable (-1000)
1: Decrease Stats by 120
2: Improved Spell Effect(Creeping Doom Trigger)
He casts this on 4 totally random people. Each of those individuals MUST find one of the "Mournful spirits" and say "shoulder my burden" in a range that the spirit can hear them or they will die in 42 seconds. ANYONE in the raid can get this, and if it is your MT, you must have the ST ready to take aggro from vish. Cast Bestow Divine Aura on the MT when the ST is ready so he can go find a spirit. Other than the mournful spirits, the only way to avoid dieing to the DT dot is to BE DAed when it triggers at 0 seconds on the timer. That means you cannot DA the moment you get it, you must wait till it counts down a bit so the da and the dt overlap each other.
IF you cannot da and you cannot find a mournful spirit, GATE, find a way to exit the zone, DO SOMETHING but DO NOT STAND THERE AND DIE SO A WRAITH SPAWNS . Gate potions can be bought in plane of tranquility.
The last thing you must realize is that VISH is totally unkillable at 24%, he will not lose any life. the ONLY way to get him below that is to get people cured from his dt. Each person that gets cured lets you drop him 1 more %. so you must get 25 people cured total in order to finish him off. There is no "best" time to kill the dpsed Cloud of concentraded chaos, but we usually do it at around 15% when we are not frantically trying to get cured.
