Death Knights are an incredibly fun class to play. Not only do they get to start out at level 55 and bypass the early leveling, but they are a powerful class that can tank or DPS. They have three very viable talent trees to choose from, but in this article we are going to focus on the Frost Talent Tree which is a DPS tree.
If you follow this simple setup you will be topping the DPS charts in your dungeon groups and raids faster than you can put a rune on your weapon!
Frost DK Rotation
The Frost Death Knight rotation is one of the highest DPS rotations in the game. Put Horn of Winter up before a fight and then only reapply as needed and if nothing else on the priority list is available. To follow this rotation list simply choose the highest available ability on the list and cast it. I suggest practicing on a the target dummies in Orgrimmar or Stormwind for a few minutes before you jump into a dungeon or raid. You can see how much damage you are doing by grabbing the addon Recount from one of the many WoW addon sites.
Here is your priority rotation:
Frost DK Gems
Your meta gems should be a Reverberating Shadowspirit Diamond.
Because strength is the top stat for a Frost DK you should fill every gem slot with a Bold Inferno Ruby with one exception. If the socket bonus is +20 STR or greater then put Etheced Demonseye in a blue slot and Fierce Ember Topaz in any yellow slots. Easy!
Frost DK Enchants
The top enchants for each slot are:
Frost DK Glyphs
The Major and Minor glyphs are not nearly as important as the Prime glyphs. These can sometimes be expensive, but just like the gems and enchants they will make a huge difference in your dps and leveling speed.
There are some incredible WoW leveling spec guides out there that will help you take your game even further. There are also some great WoW addons that will help you boost your dps and leveling speed.
