World of Warcraft at Ten Ton Hammer

As a Death Knight in Utgarde Keep there are a few thinks to keep in mind.  What those things are really depends on what you are doing in the keep, either tanking or DPSing. Overall though Utgarde Keep is a fairly straight forward instance, and as such does not require anything super special from any specific class.

Tanking

There are two big things to keep in mind while tanking in Utgarde Keep.  The first is that most groups of enemies contain a caster or two.  You can identify them easily by targeting the ones with mana bars.   When tanking them you have two options, you can either make sure you engage them first at distance and then move into the group and down them first, or you do the more Death Knight method and Death Grip them.  The second is my favourite way to deal with them.  Stand back at range, use Death Grip to pull the caster into combat, and then drop a Death & Decay to get threat on all the other enemies that rush forward to help their friend. 

The second big thing to keep in mind is to always keep the drakes faced away from your party members. The drakes in the keep act as normal dragons and have an AoE breath attack to the front.  This means you should always grab them and turn them away from your group. 

DPS

No matter your DPS build in Utgarde Keep there are a few things to remember.  In general the Keep does not have many large groups of creatures so while AOE can add some damage, it's generally single target damage.  The biggest group in the instance is 5 creatures and most pulls are 3.  On the larger pulls make sure you give the tank a little time to get threat and then keep Death & Decay up for maximum damage.  On the small pulls make sure you go after the casters first as the generally cause the tanks the most issues.  When you see casters doing something, have Mind Freeze or Strangulate ready to shut them down.

Other than those few things, Utgarde Keep is a fairly straight forward instance to tank or DPS as a Death Knight.  Just keep threat on everything if you’re a tank, or do massive damage if you’re DPS.
