This is a huge physical damage hit he will cast  WoW cataclysm Gold on the highest HP target that is second or third on melee threat about every one second, and it will hit for 30k After mitigation on a pre raid geared tank. So what we're looking for is as much effective HP as we can get to survive this in case you're unfamiliar with the effect of HP, it's just HP divided by one minus damage reduction.

It tells us how much unmitigated damage we can take without a heal before dying. So for patchwork stem and armor are going to be king. We want to maximize both of these as best we can. You should also favor picking up avoidance over expertise and hit at this point where it shouldn't be much of an issue throughout your week one raids even without hidden expertise cap, you just want to make sure you're able to get through your Patchwork, so you can clear the whole raid is the one Boston next that actually has a gear check. I'd recommend doing a Bomb Wing last year first week just so you have a chance at getting some drops from the rest of the read.

First to make things easier. Just make sure to bring some gems and enchants for any loot you might get for weapon you can use infantry assault blade for AOE and red sort of courage for single target if you're lucky enough to get both before you read Sealift Command is not normalized so slow weapons do really high SOC damage. There are a couple of big pieces in the set tempo tightened steel helm and titanium Earth Guard ring.

These aren't necessary but if you're rolling in gold, you could pick these up to be ultra prepared for week one of raids. I'm going with the austere siege diamond and helm for the extra armor. Since Patrick is the main thing we're concerned about later, you'll generally be using a full Gen scapular diamond for the reduced spell damage taken. 

If you have pauldrons of perseverance, there's still going to be great going into Phase One rates, or rings, I generally recommend the rings with defense on them over Keystone great ring, because it isn't easy to hit crit cap this early on, so you'll likely have to sacrifice stamp and gem slots to make up for the defense loss. If you're a jewel crafter, make sure to craft both figuring monarch crab and figuring Ruby hair. 

Monarch crab is what you'll generally use for bosses while Ruby hair is nice for the movespeed CD on trash and you can swap it out when the CD is down. It can also be nice for boss fights where quick movement is beneficial. If you're not a JC at generally use levantar is talisman. Now let's talk emblems, you'll get 52 emblems of heroism a day if you do every heroic and the daily quest was an opportunity to earn more through some other quests. If you're going to have time to get all of the emblem items.

My priority for these is libram of buy Cataclysm Classic Gold obstruction, chest guard of the last conquer gloves of the last conquer, chained military gorgeous and waist guard of living iron. If you get unlucky with the Royal crest of Florida on I would prioritize getting crackles discarded plate panel before your first run. Otherwise I would skip it.
