Never fear, we'll be doing more leveling posts and more report cards in the future. (I've been messing around with arms again lately on my night elf warrior -- having some fun with it, too.) But this week, we'll be talking about the Ruby Sanctum instance. The storyline of the Ruby Sanctum links Wrath of the Lich King's storylines with those of the upcoming Cataclysm, but the encounter mechanics and loot are still pretty solidly Wrath.
First we'll talk about the minibosses and Halion himself from both a DPS and a tanking perspective. Since much of that work has already been done by Michael Gray, we'll then go on to talk about loot. Then I'm gonna go eat something. I'd invite you, but by the time you read this I will have already eaten. The bane of the internet: I can't share my jalapeno-flavored chips with you. (Nor, to be honest, would I. They're mine. MINE!)
The first thing to talk about in Ruby Sanctum are the trash pulls. As a DPSer, you really just need to know what the kill order is and to stick to it, but I also suggest to be aware. Remember Ulduar on the way to General Vezax? Yeah, it's like that. There most likely will be CC, and it's a bad idea to Whirlwind/Bladestorm in the middle of it. So pay attention and use your abilities responsibly. As a tank, you should likewise watch your AoE threat moves and make sure only to break CC when you need to. Make sure to use Charge to get right back on the Charscale Invoker when it punts you, and in general, use your stuns and silences to keep the casters locked down as much as possible when tanking them. If you're tanking the Charscale Commanders, pull them out; don't let them use Rallying Shout. There's no reason to let a five-or-so-mob trash pull get a 25% DPS increase.
Once you get done with the trash, it's on to the mini-bosses.
