This is the Cataclysm Unholy 85 Death Knight leveling build guide updated for patch 4.0.6. This guide is for a player that wants to use the Unholy tree while leveling, questing and playing AoE.
In this Death Knight build guide I have given 1 through 85 talents, full glyph list and spell rotations to use.
These are the best Unholy talents to level with that go along great with the best leveling route guide: Zygor’s Leveling Guide.
Spell Rotation
Single Target (Unholy Presence):

Do You Want To Level Faster Like The Pros?
If you are having trouble leveling or need to level faster in WoW Cataclysm I highly suggest you check out Zygor’s Leveling Guide. It has the perfect leveling path that gets you to 85 faster and easier than any other way. No matter what level you are, you load the guide and it points with an arrow to the direction of each monster, quest giver, trainer etc. Its pretty crazy. It also has an in game box that tells you exactly what to do, like kill 5 boars, run west 10 miles, etc. If you dont have this in game add on guide, honestly, you are missing out. You can find out more here or check out the Zygor Cataclysm Leveling Guide Review.

didnt liked much the talent build;
Scent of Blood — doesnt add significantly rp at high levels (unless you get threat from mobs, thats not a thing to look for !)
Improved Blood Tap — adds a scourge strike, or ther magic for each 30seconds. is that a LOT of dps ??
Butchery — 2rp each 5 seconds = 1 death coil each 85; when killing bosses you get NO other bonus… should’t we focus on boss killing ? omg even worst than blood tap !
I know, there is nothing good at the frost tree, but ther is still the unholy tree ! I know there is no more good stuff dwn there, but think of it : each talent un this tree = +5% dps from diseases
think of it. calculate a bit. you’ll find out that im not mistaken
Improved Blood Tap: actually adds only one more each 60seconds… even, even worst
This build has been updated with the most popular leveling build
Why is Horn of Winter always last in your rotation? Shouldnt it always be the first thing you do before entering combat since it gives RP and increases strength? Additionally, how is it that DT is second in rotation when you have to proc that ability? Its kinda difficult to have that up without proc at the beginning of battle.
