There are a lot of discussions about SSC bosses, but not much on the really annoying and abundant trash in SSC. Such discussions would be immensely useful for guilds/raids like my own that are just starting in SSC.

My first and most pressing question:
How should we handle the Underbog Colossus that uses the Rampant Infection ability?

I've read the comments on Wowhead:
http://www.wowhead.com/?npc=21251#M0z

Even though Rampant Infection is described as a disease, I did not see a debuff even when the Colossus targeted me and I took damage from Rampant Infection. I also didn't see any debuffs if I am near the person who got the initial infection. How do we stop groups of people from taking massive damage from the jumping infection if it cannot be cleansed?

Have a Rogue sneak into Morogrim's room, aggro and leash him to despawn the six Murloc pack roaming the tunnel before him.

I thought it could be cleansed; you just have you be quick on the trigger?

Oh, with regards to the OP, I believe Poison Cleansing Totems solved a lot of deaths on that.

That's what I thought too, but I was watching pretty carefully (I was a prot warrior not tanking the Colossus so I didn't have anything to pay attention to). Also told the healers repeatedly to watch for and abolish the Infection. Didn't seem to help. Maybe they were doing it too slowly and I just missed the debuff.

My confusion is that I didn't see any debuff to cleanse. We seemed to just be taking AOE Nature damage with no debuffs.

There's definitely a debuff that hops around, slowly doing more and more damage until someone dies. I've never been able to abolish it quickly enough, though.

in the 6 naga pack right before morogrim's tunnel, have 1 warrior tank both witches up on the rock cliff while ranged dps takes care of them. This will avoid anyone being mind controlled or knocked off into the water. 2 tanks won't work because there is a chance a tank could get MC'd by the other warrior's naga.

No, it definitely keeps increasing in dmg until someone gets 1 shot. Hops to the nearest person, too, as far as I can tell.

This was posted in the wrong thread, sorry.

We have our priests spam Abolish Disease on as many people as possible, it relies on RNG but we've stopped more than a few rampant infections that way.

Clickbound disease-curing + Grid + lots of people on the ball usually does the trick on the Rampant Infection. Unless you have a good UI setup for catching/cleansing debuffs, you'll never catch it in time except via luck. You have literally one second before it hops.

The Fathom-Witch pulls outside the caverns leading to Moro/Kara/Leo were a pain until we realized that they're best OT'd far from the raid and burned with ranged DPS only. Just separate them and make sure your tanks can manage to not get knocked into the water, and keep them away from everyone else, and they're harmless.

The one trash pull that continues to annoy me are the Lurkers leading to Leo. Their poison bolt volleys seem to have nearly endless range, and the mushroom-spawning has a very large range as well. We never wipe to these, but they always feel very messy and involve a bunch of deaths or near-deaths as people run through mushrooms. Any elegant solutions people have come up with?

We put a feral druid and 2 healers on one of the lurkers, the others stay with the raid on the MA/MT's lurker. The raid itself and the 3 man offtank group stay as a clump and move as a team. You essentially take one down at a time in groups that never affect each other.

Once the tunnel or area between you and the OT group has its shrooms explode, you rejoin your companions and kill the second group.

That's been our solution, generally no deaths - unless someone stands behind the clump, but even that doesn't seem to kill anyone anymore.

Rampant infection is a debuff that you 'give' to someone else for x damage, clensing it stops this chain (I think)!

Does this mean that it is possible to attempt Morogrim after clearing only two trash packs (the 4 humanoid + 2 naga pack, then the 6 naga pack)? I've been considering trying Morogrim first as he sounds easier i execution, but Lurker requires no trash clear at all.

Spaming Abolish desease on the caster camp will help. The debuff lasts for a second on everyone before it goes to the next person, if abolish ticks in that second you just broke the chain and you win.

Personally i am also stoneforming once i see the infection going through the raid, it may break the chain. Dwarves only.

As far as I know, aggro'ing him only despawns the Murloc packs on either side of him, not the packs in the room itself.

I'd recommend (Having done this myself) doing Lurker first, as he can be done entirely without consumables. Tidewalker is very easy in concept, but unless you're decked in kara / gruul level gear, you'll have a tough time meeting the DPS / Heal / Tank requirements.

Kinda like Patchwerk.

So you're saying you can skip the two naga packs in front of his room too?

You can skip all sans 4 murloc packs, and the naga pack at the far side of his room.

Trying it right now, but nothing happens.

What exactly do you do? Have a rogue stealth in, aggro him and then vanish, or what?

There is a lot of miscommunication here. Aggroing Morogrim will instantly despawn 2 particular packs if they happen to be up:
1) The Murloc pack that runs from his room out to the wooden ramp and back.
2) The Naga pack that patrols from Morogrim's room to the bend leading to Karathress's room, and back (not the second Naga pack that goes all the way TO Kara's room, mind you).

That's it. The four murloc packs actually inside Moro's room don't despawn. You have to clear them. But they're really easy so I'm not sure why that's a big deal.

Time-consuming :P

But yeah, I thought more would despawn but just noticed 2 murloc packs and the naga pack despawned, which saves time. Quite nice.

Note that they will still respawn 2 hrs from the moment they despawned, if you haven't killed Morogrim by then.
