HEROIC - Rhyolith - DEFEATED 11/10/11

[TeaLeaf]

In Heroic Difficulty, 10 Liquid Obsidian creatures spawn around him.
Liquid Obsidian â€" The Liquid Obsidian moves towards Lord Rhyolith, and casts Fuse when it reaches him.
  Fuse â€" The Liquid Obsidian fuses with Lord Rhyolith, increasing his damage reduction by 1%.

 In Heroic Difficulty Lord Rhyolith creates 10 Fragments of Rhyolith instead of 5.

P2 - Unleashed Flame  â€" Lord Rhyolith unleashes beams of fire which pursue random players, inflicting 10000 Fire damage to all players within 5 yards of the beam's impact location.

Good addon for anyone who might DPS the legs to help steer - install it!

Bump on this for Tuesday for RGT.  We need to make some quick progress on this boss as we intend to clear the remainder of the instance on Tuesday, so let's be prepared!

Considering how laughably easy he now is post Nerf I think he should go down even with the time constraint of needing to clear all bosses.
Nice trick from the guide though, using an AA priest as the tank healer on the spark.

[TeaLeaf]

The only way we could do that would be with me running AA/ atonement spec as I do not think Amber has that spec. I do not anticipate dps as being an issue though, so it may not be needed given the Nerfbat that was applied to this boss twice already.

If "do it as normal, but focus on proper execution" is what we have to do, it could be a loooong night judging from last night's raid ;-)

Nah in all honesty I can see this go down. Just get rid of adds in time, stay alive and dodge lazerz in P2.

[TeaLeaf]

Basic difference as I see it is:
-try to avoid doubling back on yourself when driving Rhyo (little oozes are following him, so just keep kiting)
-more dps needed for the adds (but we're way ahead of the curve there anyway), slightly more healing from melee damage from adds.  Planning to one tank it again, but we'll have to see if that option works.
-P2 is a marginally more movement required fight due to the addition of 'pewpewlazerbeams'.

Other that it should go smoothly if we can not stand in fire....!

The difference here that that for heroic we had to treat Shannox with a radically different strat, whereas this is exactly what we've been doing.

While there's a certain RNG involved with the volcano spawns, so far we've more or less always driven Ryolith in a 'circle' -> that is, always the same turn direction. I haven't had to go zig zag yet as I recall it. Should be good.

If you only turn in one direction we get an achivement too

Has to be left though I think? I'm more of a right kinda guy ;-)

I don't have a clue about how to solve the stacks at the moment but those wern't our only problems with him.

The leg group had a very big problem with the boss making some weird huge turns and then sort of auto ajusting himself. Those moves where a big pain with doing the calls and the movement.
Also with a Concussive Stomp it went on with those weird movements.. Normally with a stomp he resets our movement but today i had a feeling that didn't always happen.

Another note is that with our movement even a full circle around the area will not stop loads of those little adds reaching him at some point in the fight. With each stomp they get closer and closer and hit him...
The boss continues his movement after a stomp pretty late which gives the adds loads of time.

Also with the dps needed on the boss there is no real change that the melee is able to kill them, not even with splash damage. i tried it 2 tries and at the end i killed a few but a few aint enough and the dps on the legs dropped way to much.

Near the end it was a lot better than at the start. We were getting far less damage boost stacks at the end (0-3) and his armor stacks were dropping a little faster too. Still too slow though, or we're not doing enough DPS, or both. It seemed to be he was at 30-40 stacks of armor at ~1 minute before Superheat. You can manage with a bit of superheat at the end of phase 1, but not much longer than maybe 10 seconds. The longer he stays superheated in P1, the bigger his damage boost in P2. This was the damage boost I was thinking of.

As a driver (apart from the silly confusions of left and right xD), what's most troubling is finding a balance between avoiding inactive volcano's (will boost damage done if he steps on them) and kiting/avoiding oozes (will increase his armor stack). With our current dps on the legs - that is Grim, Noreia and me - we can't seem to do both. When we add more DPS (as we did with Sheepy), obviously the boss goes down faster but he also becomes a lot harder to control, increasing likelyhood of stepping on inactive volcano's, increasing his damage output.

Add in the RNG of which volcano's become active and where - right next to 2 dormant volcanoes is very different to being on its own somewhere far away from others, which again is wholly different to three active ones in a line - and you have a pretty challenging fight.

All in all I think legwork isn't too far off. Especially in the later tries we were getting lower stacks of armor/dropping off entirely and having very little to no damage boosts up by the time he hits Superheated. However he would often be at 40-50%, which is still pretty far off from the 25% we need.

N.B.: I'm about 80% sure that if he loses all his armor stacks, the little oozes will not add any stacks back when they reach him. So if we're lucky we can get a couple of clustered active volcanoes, that will instantly drop him down to 0.

One of things we could do is drop to 2 healers which would give us the ability to put another on the legs full-time.  However;

I think our problem last night was our dps.  Put simply, last night our dps on Rhyo was horrible.  During the decent length tries, we just peaked over 100k rdps, which is a little higher than the average dps of the average wipe on WoL for this boss.  We need to be seeing closer to 130k rdps which is the typical rdps for a HC Rhyo kill.

Across all the wipes (which will understate slightly our actual rdps) we did this:

Name|DPS|DPS(e)
Teaell     |24895.1   |20255.8   
Sheepat     |16343.1   |14275.9
Jesung     |18072.6   |14088.2   
Grimnar   |12819.3   |12291.1   
Whytee   |13231.0   |11457.3
Torgen   |11573.7   |11295.1
Noréia     |8536.8   |8072.9
Totals   |92250.7   |91883.6[/table]

There's our problem.  Now the numbers are skewed so take them with a pinch of salt.  They include *all* of our wipes, so shorter tries with fewer adds or dps time will mean the numbers show lower.  AOE-whores like me will look pro for no good reason simply because I get to AOE 10 adds every 30 seconds, so AOE needs to be discounted.  Torgen has to make steering calls so has a harder time on rotation, so his figures will be lwoer due to his role.  Legs DPSers have to swap targets all the time so might be a little nerfed.  BUT we still have issued with the level of DPS and need more.

We have 6 dps in the group.
We need 30k more rdps.
We need 5k more dps per person.
How do we get it?

• Make sure that DPS on the legs starts when the fight starts, let's not wait for the first direction call from Torgen
• Pre-pot for the start of the fight
• Heroism will be called prior to Super-Heated as per last night (this boosted our DPS)
• Drop one AOE dps from the little adds and move it to legs full-time
• Make sure that you are *always* DPSing something, no gaps - if we're doing this we'll get more rdps
  
• Any other ideas?

(There are a few 110k rdps kills, but I'd like a safety margin above that please!)

I think our problem last night was our dps.  

I disagree to some degree. Our problem last night was... That we took too easy on the task. We were not fully updated on boss mechanics before we started the pulls.

As the night went on, we learned more and got more confident in all aspects of the fight. We caught up with him... Last try was at 20% and he had a couple of stacks (Superheated) at that time.. If we just repeat the cycle, we will be able to push him into p2 without any stacks at all.
Dps always rises when all understand the mechanics.

Btw; We should have some calls for when to switch DPS to Legs-> Spark -> Rhyo when things are heating up.

Edit; Healing perspective p2:
Seeing the death log for Whytee on the last try makes me happy. Jas was the only one who healed him last 10 secs. :-)
We need tank to call out when Rhyo goes "active". This way we can throw some heals on MT/HoT him up. You might think us healers are able to see when the taunt is made... but this is not clear to us at all yet.
Fact: Rhyo hits for 50k on Whytee every 2 secs. In addition to this, the immolation ticks for 10k every sec.

[JonnyAppleSeed]

Looking on logs from other guilds a 2 healer strat seems to be the norm. The kills seem to be under or just after the 5 min superheat. The Healing out is around 20k hps eeek
