Emalon the Storm Watcher - Vault Boss #2
So,
Something interesting/fun to add into our OS/Vault run on Fridays.
Emalon the Storm Watcher is the new boss added in 3.1. He is a major step up in difficulty from Archavon and drops Tier 7.5 (Valorous) Loot in 10 man and T8 in 25 (Heroic mode). I would definitely like to "pay him a visit" after we down Archavon (assuming we own/win Wintergrasp) on Friday.
Here are the usual comments/strategies from WoWHead. Below is a major wall of text on one of the better write-ups I have seen on the fight:
This is a fun, fun, fun fight, one of the best-tuned Blizzard has ever created. It had better be, because the fight has many moving parts. In terms of complexity and overall difficulty I'd easily put it on the level of Malygos (including phase 3), and above any Naxxramas fight except, maybe, Kel'thuzad. (You know the twenty seconds before and after the Lich King sends Kel'thuzad help in phase 3? This fight is sort of like those forty seconds looped over and over again in a room half the size.) Yes, it's definitely harder than Thaddius, Sapphiron, or Gluth; I'd put it slightly above Grobbulus, too.
After unsuccessfully attempting the boss from 3.1's arrival on with four different pickup groups on both 10 and 25, my first kill tonight was in a 10 group I led made up of people I knew could perform under pressure; definitely not your average pickup group. Most of us had seen the fight before, too. Thankfully, with the resurrection site now right outside the instance entrance, wipe recovery is 30 seconds flat. With all that going for us it still took us a full 90 minutes and two heartbreaking wipes with the boss under 5%!
What makes the fight so fun/complex is how its various elements directly conflict with each other:
Ranged DPS is preferable: On 10, at least, it's possible for a smart ranged DPS to find a nice spot away from everyone else and just hit whatever needs to be hit. There is no raid damage for ranged if positioned right.
Melee DPS is preferable: Well, certain kinds of melee, at least. If I have a choice of a lower-DPS ranged or a higher-DPS melee--especially a burst-capable DPS like a rogue, DPS warrior, or enhancement shaman--I'll take the melee every time. The boss has a big hitbox and a melee-heavy group can definitely succeed if everyone takes care.
This is not a DPS race: It is, 75% of the time, a survival fight. The boss does not have a ginormous number of hitpoints. DPS should save their long-cooldown attacks for the adds, and meanwhile focus on positioning (because of the Chain Lightning) and, if melee, running away from the Lightning Nova when cast.
This is a DPS race: DPS must understand that when the raid emote occurs they must drop whatever they're doing and shift to whichever add has the growth buff. This is the time to use every long-cooldown attack.
Threat matters at the start of the fight: The adds and the boss hit hard enough that tanks will need healing almost immediately, which risks an aggro pull. Ideally, a pull will go like this: a) Add tank rushes in and gets aggro on the adds and the boss. b) A rogue or hunter uses Fan of Knights and Tricks of the Trade/Volley and Misdirect to reinforce the aggro lead. c) The add tank's healer starts healing. d) The boss tank taunts Emalon and moves it to the designated spot. e) DPS only now start hitting the boss.
Threat does not matter after the initial pull: As a paladin tank I found that my normal threat rotation was damaging the adds too fast, risking an eventual "off-cycle" add spawn from Emalon. After the first 10 seconds of the fight I simply switched to autoattacking, Holy Shield, and Consecrate, while mentally preparing myself for the frenzied search to come for the buffed add. Once that add died, I looked for the newly-spawned add and taunted it. (Have the boss tank grab the new add first; then the add tank can grab it at his leisure, instead of it possibly rushing to a healer or DPS and killing him.) Hit-capped gear to eliminate taunt failures is highly advisable.
The strategy I favor is for the boss tank to pull Emalon to one of the two back niches (the green-colored ones visible from the top of the stairs, while the other tank pulls the adds to the middle of the room to minimize travel time for melee. When Emalon casts Lightning Nova, the tank and other melee should move to the other back niche, and wait for the boss to come to them (Remember what I said about it not being a DPS race?), meanwhile adjusting positioning to avoid Chain Lightning. Continue fighting until Lightning Nova occurs again, the move back to the first niche.
I don't recommend marking the adds ahead of time. Extra raid markers make it harder to pick out the right add out of the crowded group, especially when enemy healthbars are enabled. Instead, a) have the add tank quickly look through the adds to find and mark the buffed one, but b) it's also important that each DPS use his own eyes, find the add that's been healed to full health (that's why enabling enemy healthbars is important), and target it themselves. Every moment counts.
In closing, this is not a fight that groups will be able to anytime soon overpower with gear and without strategy. The combination of Chain Lightning and needing to quickly shift targets to one of four random choices means that Tier 9-geared pickup groups will repeatedly wipe. I'm glad I was able to finally beat Emalon, I'm glad I helped get two players what might be (given random numbers and the level of progression on the server) server-first T8 pieces, and I can't wait to fight the boss again. Thank you, Blizzard.
