Gehennas strategy

[Duerdon]

Small post I found on Gehennas....might be usefull. :)

Gehennas: Physical attacks, fire attacks, shadow attacks (Use fire resist but have priests can shadow resist on all raid members).
This boss is basically Lucifron on crack. The general idea in how to fight Gehennas is similar, as is what is necessary to win. First of all just like Lucifron he has two adds that must be defeated which requires the raid to be separated into basically two fights in two areas. On top of this he has a very nasty curse that decreases healing by 75%. Lastly he has a nasty area of effect that must be paid attention to, like Magmadar, and shadow bolts that randomly like to pulverize unsuspecting people. Basically for this boss to be defeated elements of the first two boss fights must be combined and executed. First off the main tank group and a backup tank should be maneuvered away from his spawn point and back to the left (facing him). This should provide adequate area for him to AOE to his hearts content without hitting the larger half of the raid. Additionally the two adds should be pulled and tanked to the right creating more space.
Group 1 – Ten to twelve people consisting of two healers in each group, two warriors well equipped for tanking, and at least three de-cursers. It is essential that the de-cursers immediately remove Ghennas’s anti healing curse. On top of this they most constantly be moving out of his rain of fire area of effect. If this is done and proper healing is applied to the main tank without the tank losing agro the fight is not terribly difficult.
Group 2 – Thirty to Twenty Eight people should consist of at least two warriors as well as a large amount of DPS. The idea is to tank the two adds and eliminate one then the other just like Lucifron. The adds are not terribly difficult, the most annoying thing they do is a stun called Hand of Ragnaros. This can cause a tank to momentarily lose agro but since their damage is not terribly high the two adds should be defeated with minimal losses. Once this is done this segment of the raid moves toward Gehennas and defeats him as well.
1) Most important thing about Gehennas is that the pull is executed correctly with hunters pulling the adds and Gehennas to their respective tanks. If this is done correctly Ghenennas won’t area of effect the entire raid and blast them with a nasty curse. If done incorrectly it can be one hell of a mess.
2) Proper de-curse prioritizing and execution. Tanks must be de-cursed immediately as well as other crucial classes like healers due to Rain of Fire and Shadow Bolts.
3) Efficient use of healing by utilizing bandages and having non-essential classes move out of range and heal themselves. This makes for more efficient use of healing on tanks. Additionally rain of fire should be avoided by all raid members to maintain efficient use of mana.

From my healing perspective on this fight, I found it to be the most challenging yet.

When I first asked what to expect on Ventrilo someone replied that it was kind of like Luci and Mags rolled into 1. That is a better description of what to expect then anything I could come up with.

On our successful run at him I believe it was set up like this, correct me if I am wrong.

3 healing groups
1st Group on the MT that is tanking Ghenennas
2nd Group on the MT that is tanking Ghens Buddy #1
3rd Group on the MT that is tanking Ghens Buddy #2

A few healers had specific classes to keep up, (Example: Muddus was healing the healers, someone else may have been given DPSers)

2 Out of Combat ressers
2 Or more people aiding in the Decursing

Essentially you must have the decursing be very on point. If the MT has the 75% decrease to healing curse on him, he is going down, and on the first two attempts at him tonight I know I was a bit slow on him and I am reasonably confident that when sol went down it was a result of the curse not allowing us to heal him.

Another part that I felt was key to the success was the length of time the fight takes. A rotation of healing groups was necessary. With this fight the easiest way to make the rotation possible is with mob deaths timing it.

To draw an example of this, the fight will go in the kill order of Ghens Buddy 1, then Ghens Buddy 2 then Ghenennas himself. When Buddy #1 dies healing group 2 steps out until back at full mana or until the other healers are going oom. Same thing for healing Group #3 when Buddy # 2 drops they can step back and grab some mana and then they are all set for backing up the other healers that are running OOM healing the rest of the raid, or decursing. This creates a system where theoretically we have healers at all time with enough mana to do the job.

Aside from that, probably the hardest part is running around to avoid the rain of fire, and the random shadow bolts that hit for 2000 damage at times. I for one felt death ensue from both during our learning the fight.

If I messed anything up in that please let me know, I am about 98% sure that is the just of how the healing side went.

I had Sol targetted the whole fight just to ensure he didn't have it on him. Just like to thank the person healin me. Hard enough to dance around the fire, stay in range of MT and eat the occasional bolt. It's the shadow bolts that really sting. I'm going to look for some more shadow resistance.

I've got some of the cloth shadow resist gear from silithus. Boots I think. Mats aren't too bad if I recollect, 6 runes.

saw a cloth belt with 25 SR on it and some int on the ah last night for i think 20g - maybe 40.

Yar to everything Shebus said.

The only thing I'd add as the healer of the healers, there were a few occasions where a couple of people would get out of range. The problem is I'm not sure what direction that out or range is. :p

Shebus was up against a pillar that I had line of sight issues on and so he dropped several times If it's possible to move closer to where Duer was standing would have helped me a ton (should have brought this up sooner).

Other than that I thought the last attempt went pretty smooth. I think the Soulstones on multiple healers helped too, but I'm not sure how many people had to use them.

Was very awesome to see a 3rd boss drop, well done to everyone.

Learned backup tanks should not spam out herioc strike. I attempted to ping pong a guard with bloodrush and it failed miserablly due to lack of healing and rightly so since the healers were observing BR and not myself. I wanted my threat level next in line to BR's. My rage gen seemed much higher from my hits allowing me to pull the guard off BR by spamming my specials with higher threat gen. My attempt was to ping pong and let BR heal up in between.

From my observation, its not necessary. Normal attacks with minimal specials will work just fine. When a MT passes away, all dps needs to hault, dont run, unless under AoE, and let the MT regain control.

Personally I enjoyed the dps aspect critting nearly every hit (and seemed like sword spec may actually be proccing with my mace sometimes) resulting in regular crits of 900-1700 nearly every swing with execute crits up to 3400.

With the mod that pp put on trial last night, it significantly reduced our idle time dealing with drops. I personally still remain skeptic of it until more testing, but seemed to be effective for the raid. We may have all 3 bosses completed on one night by end of December.

May not tell you the direction but may be of support to let you know your range.

One other thing I noticed last night. Within seconds of Sol charging either Shebus or Zeg (and sometimes both) would drop in health immediately (or within the first 2 seconds). Do either of you know what caused the damage? I'm curious because on one of the fights we lost Zeg almost immediately and I'm wondering if we could slightly adjust where we stand when we start out. If it's an attack from Geh or one of the guards it should only take a few seconds to be in a different spot right as the pull started and then move to your "position".

Saw Zeg nearly die a few times from the Rain of Fire. That spell will drop you fast. Even running out of its path with 5700 buffed health it would slay me. FR didnt seem to make a difference either. Im potion farming before our next encounter.
