Spiritual Guidance: Healing Chimaeron and Atramedes as a priest

This week on Spiritual Guidance, we'll be returning to Blackwing Descent where, after meeting sudden and untimely deaths at the bottom of an elevator shaft, we can respawn and face our next two healing challenges: Chimaeron and Atramedes.
You may recall that not long ago, we examined two other bosses in Blackwing Descent, Magmaw and the Omnotron Defense System. If you can handle those two, these bosses are just a tiny step up in difficulty and should be no match for your priestly prowess.

Chimaeron
Of the three bosses in the middle ring, Chimaeron is probably the most difficult because your success on this cutie hinges on the coordination of you and your fellow healers. If you know what to do and stick to it, the fight is fast and easy.
Before we get started, make sure you learn the basics of this fight first. WoW Insider's guide to Chimaeron is a great place to start.
The first thing you need to know about this fight is that who you heal is important, not how much you heal. Chimaeron's abilities constantly risk killing players, but because of the Bile-O-Tron 800 and Finkle's Mixture, as long as players are always at about 10,000 HP, they will live. Extra healing is just wasted mana. The only exception to this is when the Bile-O-Tron is knocked offline for a few seconds. During that time, you'll want to go all out to keep your raid alive.
Let's go over the specific abilities you'll be dealing with and how to handle them.
- Massacre Periodically, everyone in the entire raid group will get hit for their maximum health with this ability. Because of Finkle's Mixture, though, they'll survive with 1 HP left. To survive any attacks after that, you will want to quickly (but efficiently; you do have a little time) heal every member of the raid up to 10k health. Prayer of Healing is great at this.
- Caustic Slime In the periods between Massacre, Chimaeron will hit players with this ability. Your raid's strategy should involve spreading out (to avoid sharing damage with other raid members from this attack), so you shouldn't have to heal more than just the players targeted with Caustic Slime. Caustic Slime is what is deadly in this encounter, because it will knock your fellow raiders' HP below 10k health. If this happens shortly before a Massacre and a player isn't healed to 10k quickly enough, Massacre will kill that player. This means you'll want to save fast, instant-cast heals like Penance and Holy Word: Serenity for the third (last) round of Caustic Slime in each cycle of the fight. Don't use them on the second round, when there is plenty of time to use cast spells like Flash Heal. This is probably the most important thing in the fight to know as a healer.
- Double Attack This ability is designed to kill your tank by lining up two melee attacks back to back. Chimaeron attacks slowly, though, so as soon as Chimaeron gets this buff, you'll want to combine defensive cooldowns and heavy heals on whoever has threat on Chimaeron -- usually the off tank, in most strategies. Guardian Spirit is especially good for handling this ability, since it's designed to be lethal. (Tip: If you watch Chimaeron in a focus frame, you can see him getting the Double Attack buff, thus making it easier to time your cooldowns and healing.)
Whenever the Bile-O-Tron is knocked offline, it's important to group up your raid and use as much AoE healing as you can to keep everyone alive through Caustic Slime. When you're grouped up, the damage from Caustic Slime will be spread out between players, but it still hits for a lot, so constant healing is needed to survive all three rounds of the ability. After the third round, players need to get healed for over 10k so that when the Bile-O-Tron comes back online, you'll be ready for the next Massacre.
When the boss gets to around 20%, he will gain Mortality, which will make it impossible to heal members of your raid any further. Most healers switch to DPS, but as a priest, you can use Power Word: Shield -- even if you're a holy priest -- to help protect players from future attacks if they are below 10k health. You can spam as many shields as you're able, but focusing on players with the highest threat is the best way to ensure your shields get used. Start with your tanks, then your melee DPS.
Discipline strategies You won't have much need for shields on this fight, so stick to spells like Penance and Flash Heal for Caustic Slime and Prayer of Healing for massacre. Use Power Word: Barrier for when the raid needs to group up for Caustic Slime; you'll probably be able to cover every other cycle if you're the only disc priest in the raid.
Holy strategies You can switch between Sanctuary and Serenity for your Chakra stance on this fight, but staying in just Sanctuary is fine since it will strengthen your talented Renews. As I said earlier, use your instant-cast heals for Caustic Slime victims before the Massacre: Circle of Healing, Renew and Holy Word: Serenity. Holy Word: Serenity is obviously the best for this job, but since it has a cooldown, you can use Circle of Healing and Renew for any stragglers who still need healing. These spells aren't guaranteed to do the full amount of healing you'll need, but combined with other healers in your raid, it's usually better than nothing. Holy Word: Sanctuary and all its underwhelming glory is great for Caustic Slime stacking when the Bile-O-Tron 800 is offline.
Disc or holy? Either. This fight has plenty of opportunities for either spec to shine, and since most of the damage being dealt with is single-target, neither healer has an advantage.
A final note on Chimaeron: It's important to know that players who are below 10k health will receive a debuff called Low Health. If you orient your raid frames to display this debuff (I talked about this previously), you'll know exactly who needs to be healed at any given time during the fight instead of trying to read the health bar of every player.

Atramedes
The second boss we'll be looking at today is the blind dragon Atramedes. In theory, this fight is easier to heal than Chimaeron, but since the fight places a lot of responsibility on individual players to not take damage, how difficult the healing is depends on the skill of your raid. If your fellow raiders are really good at movement fights and staying out of fire, this fight will be a piece of Chocolate Celebration Cake. If, on the other hand, your fellow raiders seem to be drawn to fire like junior campers with a bag of marshmallows, you may want to get ready for some wipes.
Whatever your situation is, however, make sure you get acquainted with the basics of the fight before you get started. WoW Insider's guide to Atramedes is a good start.
The encounter with Atramedes consists of two phases, a ground phase and an air phase. In both phases, raid damage is going to be the primary focus. Tank damage exists, but it's easily managed as a part-time job by one or all of your raid's healers.
Now of the raid damage you're going to see, most of it is avoidable by players. This means most of your healing will actually be spot healing problem players in the raid who can't stay out of stuff. Problem players are only healable to an extent, though; most of the damage that players can take will raise their sound level, which can eventually result in those players being one-shot by Atramedes. Though holy priests can counter the one-shot with a Guardian Spirit, timing has to be precise, and by the time you get to a killing attempt, most of your players should "get it" and not be stacking up their sound levels anyway. That said, be ready to spot heal anyone who takes additional damage, since sound is reset several times during the fight, giving those players a clean slate.
There is a bit of unavoidable damage in this fight in the form of Modulation. This ability only occurs during the ground phase and will hit your entire raid for damage and a small amount of sound. Preemptive HoTs, shields, and well-timed, pre-cast Prayers of Healing are ideal for handling the damage.
There is one last thing priests can do in this fight that is especially helpful, and that's using Leap of Faith. Both ground and air phase require a player to kite Atramedes' attacks in a way that keeps the raid and the kiter safer. No assistance should be required by the ground phase kiter, but during the air phase, Atramedes will continually get faster in his pursuit. Priests can help by strategically using "life grip" on the kiter when he gets close to being caught up to by Atramedes. You should be able to do this every air phase; if you have multiple priests, you can set them up in predetermined locations to guide the kiter along a safe track.
Discipline strategies With the increased mana cost of Power Word: Shield, Atramedes is actually one of the more problematic fights for disc priests to heal because we either have to play with the idea in mind that we will probably run out of mana or playe conservatively with fewer ideal spells for the job. Penance is great for spot healing targets, but holy's Circle of Healing is amazing for dealing with the many random players who can, at any time, take varying amounts of damage. Prayer of Healing will be your primary tool, though disc priests will probably want to find an amount of shields they feel comfortable constantly putting out and keep doing that in preparation for Modulation.
Holy strategies What Chakra stance you use depends on your raid size. Serenity is great for 10-man, since one Prayer of Healing combined with a Circle of Healing resolves most of your raid healing troubles. In a 25-man, Sanctuary is obviously better. Talented Renew is very good for players who need just a little extra healing.
Holy priests should also be aware that in the ground phase, Body and Soul or any kind of speed increase can be problematic if given to the kiter. In the air phase, Body and Soul is fantastic, but in the ground phase, you can inadvertently kill your raid if your kiter and raid aren't expecting a sudden change in speed. This is because the attack being kited moves at the same speed as the player targeted with the attack. If the player moves faster, Atramedes will just move faster to keep up, which can become a problem if the kiter catches up to anyone in your raid trying to stay out of the way. So be careful how you use your shields in the ground phase, and be sure your players know how to respond to any speed buffs they do get.
Disc or holy? Holy all the way. Disc can manage on this fight just fine, but holy's natural strength at handling random raid damage quickly and efficiently excel here. Body and Soul is also great for personal use to avoid mechanics and move closer to players who need healing but might be out of range.
And that wraps it up. if you have any questions, be sure to leave them in the comments. Next week, we'll be finishing Blackwing Descent with Maloriak and Nefarian.

"You may recall that not long ago, we examined two other bosses in Blackwing Descent, Magmaw and the Omnotron Defense System. If you can handle those two, these bosses are just a tiny step up in difficulty and should be no match for your priestly prowess."
This hasn't been the case for my raid when it comes to Atramedes, mostly because the sound mechanic seems really buggy and ringing a gong doesn't always reset people's sound. Throw in the fact that the range of the "sound discs" is often bigger than their graphic, and it becomes a really frustrating fight even when a raid is performing well. I've only done it on 10 (where it often takes us several tries to get him down even though we got our first kill long ago), but I dread the thought of doing it on 25.
Boobah Mar 7th 2011 5:13PM
Is there any ability with a visual effect that you want to avoid that isn't bigger than it looks? At least in Cataclysm, my experience says, "No."
wutsconflag Mar 7th 2011 5:25PM
It's funny, since I seem to have the opposite impression. Often, the rings seem smaller than their graphic, since I swear I brush them, but get no sound from it. (Not that I don't keep trying to get out of their way, of course.)
wutsconflag Mar 7th 2011 5:07PM
Our raid just got Atramedes down last night and we're working on Chimaeron (best attempt was 14%). This is some helpful information I'll pass along to our priests. :)
Helios Mar 7th 2011 5:26PM
Atramedes is blind so the turn speed of his Sonic Breath increases based on the target's sound level. Hence, Body and Soul is fine for both ground and air.
Against Chimaeron I disagree that Holy and Disc are equally good. Circle of Healing while in Chakra:PoH verse Cuastic Slime is epic. Your CoH CD is faster and the spell is more powerful. Renew in Chakra:PoH is also more powerful and can be effective when spec'd right as a instant cast when CoH is on CD. Also, when Bile-O-Tron is knocked out I'd much rather be using Holy for AoE heals than spamming shields. The only time I can see using Disc verse Chimaeron is if you are having trouble with the achievement of having eight or more alive at the end.
Theresa Mar 7th 2011 5:39PM
I have the opposite experience, in ten man at least. I find atonement heals with the raid clustered around Chim to be amazing since the damage is often healed as quickly as it goes out. During the feud I don't bother with shields - pop AA, use PW:B if its off cooldown, use power infusion on myself if its not. With this combination I've easily hit 40k hps during the feud - more than enough to keep my raid alive.
Skarn Mar 7th 2011 7:16PM
Since I'm here, anyone got any tips for kiting? Ground phase in particular. We've not had many shots at Atramedes, though we took down Chimaeron without too much trouble. We're clearly doing SOMETHING wrong because often our kiters just find the breath unavoidable. For example, our kitty druid hit dash and raced away as soon as he was targeted, but the Beam still tracked him down and roasted him. He did run straight away from the boss, not in any sort of circle so we wondered if that was it. Some of our other players tried the circle run and it still didn't seem to help. Since so many people have killed him, we are obviously just missing something.
Air phase I think we'll be fine with good use of Sprint, Dash, Leap of Faith and so on. One question though: How soon do you hit the first gong in air phase? It seems like we should be hitting it pretty soon, our first target in air phase also gets destroyed since it's difficult to predict.

@ Skarn
It really depends on your group setup - but my guild has usually one or two rogues and a druid on our attempts (we actually managed a kill last week! YAY!) who are assigned to air phase gongs, and our ranged (mage or hunter) to the ground phase gongs. If you're talking about kiting during the ground phase, our practice is to have the targeted person (who will be the person with the most sound, in my experience) run to the left/clockwise, and everyone else runs right/counterclockwise. We also tanked him where the little hallway ends, facing where the bell was, to make gonging for the ranged easier - they're assigned to the gongs farthest away from the door.
When he takes off for the air phase, he should once again target the person with the most sound for the flame breath ability - which generally will be either ranged or a healer. Have someone assigned to hit one of the gongs nearer to the entrance of the room (so you don't make things harder for Searing Breath during ground phases), who will be able to kite the flame efficiently. A couple of suggestions are rogues, since they have a one minute CD on Sprint as opposed to a druid's three minute one (not to mention, the Glyph will increase your speed to that of an epic ground mount for its duration), and warriors, because of Intervene (not like they can hit Atramedes in the air, so switching to Defensive Stance for an Intervene doesn't really affect their DPS). A warlock might also be able to do this if he/she/it puts a Demonic Circle in a good place, though I can't speak for sure on the subject. You always want to keep the flame breath as far away from your raid as possible, since it increases sound and kinda hurts a lot - personally, I usually run the flame towards the back of the room, up to where the bell was, tracing a path around the outermost part of the room, and then start heading back to the front of the room. By that time, either air phase has ended, or I get Life Gripped to our priest for extra awesome goodness.
As Dawn pointed out, Leap of Faith/PW:S+Body and Soul makes flame kiting really quite easy. It actually makes a huge difference on the survival rate of the kiters (namely, me) during the both sets of kiting, since the shield is also capable of eating a tick or two of the breath beam cannon. The real trick to this fight, to be Captain Obvious for a second, is really execution - your raid has to be really aware of who's targeted when, and for the ground/air phase changes. And Searing Breath. Can't forget that ability.
Hope that helps! Good luck!

No mention of Binding Heal for Chimaeron? I find this to be one of the most useful abilities in my arsenal if I get hit with caustic slime.
Dawn Moore Mar 7th 2011 5:57PM
I spaced it. Thank you. I'll go add that in right now. (there would be a less than three heart here if the comment system allowed it)
Saltypoison Mar 7th 2011 6:00PM
Thanks! :D
Dawn Moore Mar 7th 2011 6:12PM
There, added that plus a paragraph on general assignments. I was running late on my article this week and was really focused on keeping the word count so I just blanked on both those. Thank you for the help =)

Dawn Moore Mar 7th 2011 6:22PM
Cutaia! you sneaky sneaky... HOW DID YOU DO THAT? It always cuts off the rest of my post if I do it =(
Skarn Mar 7th 2011 6:34PM
@Cutaia
Showoff. ;)
Pathros12 Mar 7th 2011 6:24PM
I'll throw in my two cents.
Chimaeron is very easy if you have strict healing assignments.
My guild downed Chim. in a few attempts once we mastered certain healing assignments.
We ran a standard 2 tanks, 3 heals, and 5 dps. Don't worry too much about the last phase. If you lust then only around 3 to 4 people will die (depending on lucky dodges, etc.)
One healer is assigned to heal Group One from TOP to BOTTOM in priority, THEN Group Two from top to bottom. Another healer is assigned to heal Group Two from BOTTOM to TOP and then Group One from bottom to top. The last healer heals the tank(s). It works simply like this: If two members are hit with the Caustic slime in the SAME group, then the two raid healers follow their respective priority. For example, if a Holy priest was assigned to heal group one then two from top to bottom, he or she would heal the top member that was hit by the slime and the (let's say Resto Shaman) second healer would heal the bottom, since the second healer works from bottom to top.
Of course, if the members are in different groups, then the respective group healer heals that member up to 10k. This also means if the healer is hit by caustic slime, then you must remember your priority first. If you have multiple healers healing the same target, then they might miss a player and cause a death. If you stick to your priority and assignments then healing raid members over 10k is easy.
Please feel free to add anything I missed. Oh....of course, when the raid stacks up for Feud/Bilo-O-Tron goes offline, then heal everyone to top. Duh! :D
Pryn Mar 7th 2011 6:36PM
I think disc might be getting a raw deal in your Atramedes appraisal. We're plainly not going to be awesome raid healers due to the current meddlings and shoe horning of our spec, so on a fight like Atramedes we just have to be ready to play to our strengths and not try to be something the designers dont want us to be :)
There is still a tank that needs healing for a start! I use AA Spec and its very efficent for minding the tank and melee, its also pretty nifty on the air phases. PW:S are also handy for folk dodging around in air phases, so that when we collapse back together for a ground again, people are in stronger shape.
Be it 10 or 25 man we are not expected to solo topup the raid, but we can still bring our own little share to the table with PoH>DA>PoH-Glyph and do our part to to keep everyone that little bit safer while the AoE Heal pros pump out their good stuff. PW:B doesn't get a chance to shine as there is so much movement in the fight, however using an alternative glyph choice to increase healing on everyone within it by 10% can be some real breathing space when Searing Flames is on the way.
While I'll hands down agree that Circle Lightwell and Body & Soul are utterly brillant on this fight I think Disc has its place depending on the healing team setup and the Disc priest having a role that aligns with our playstyle at present. If you want to heal this as Disc it is completely viable.
Glonk Mar 8th 2011 3:57AM
A question on Chimaeron. We're just about to do him in my guild and I was wondering is it possible to use PoM to counter double attack? Mine hits for over 10K so I was wondering if its viable to use this to just have one tank? Or does lag / other damage about kill this idea?
boonoob Mar 8th 2011 4:51AM
Why write a long article when you could have used 3 letters; PoH.
Ed-tron Mar 8th 2011 6:38AM
I'm confused by the Caustic Slime part: Does the raid bunch up or spread out? Bit tired from reading uni stuff, sry
