AKA "the boss with the slimes." This seems to be the second Heroic boss most people are killing.Icy Veins strat guide
No video because we all know what the fight looks like and don't need to watch some elitist's "perspective" video with hardcore soundtrack in which a quarter of the screen is covered by a damage meter.
The difference for Heroic is an additional ooze mechanic to deal with in each wave. And of course everything has more health and does more damage.
Icy veins recommends a kill priority of Yellow > Green, unless
there is a Red ooze present, in which case we need to take out Green / Purple first so we can stack up and AoE heal.
I'll look into whether a mod exists that can process the above or if we will need to work it out on the fly. ^^
Most of the difficulty in this one seems to be healer co-ordination, with about half of ooze combinations having purple present, healers will need
to set up their raid frames to monitor Deep Corruption
stacks on heal targets. I'm told there are a few strategies to get heals off without triggering Deep Corruption, like spamming direct heals on pets to cause procced heals like Efflorescence and Beacon and that Shaman smart heal thing. Probably something healers will need to research or we might end up losing a lot of raid time to trial and error.
We'll likely need to co-ordinate tank/healer CDs for the tank towards the end of each boss phase as the stacking debuff gets higher, but I don't think we'll need to double-tank it. Having a dedicated tank healer may be helpful for Deep Corruption phases so they can cast four big heals on the tank, wait for the stack to drop, repeat. Syrannia will probably end up using [Stay of Execution]
and [Mirror of Broken Images]
for extra CDs, but we'll see how we go.
As for DPS, seems like they just need to stand in the right place and kill the right add first. Nearly every wave will include AoE adds so spec accordingly.
We'll need to work out as we go stuff like what combinations we have the most issues with and how many people we need to switch to oozes. I don't imagine the enrage timer will be much of an issue for our group, especially post-nerf.
