Frost Death Knight Guide
First of all the icy chill in the air is under your command. You blast your enemies with freezing air and when the time is right, you freeze anyone in your presence, leaving them vulnerable to your vicious intent. Frost death knight is a dps spec that can be used for both PvE and PvP, Frost Death Knights use dual wield and can also inflict frost damage by Howling Blast or Frost Strike, Like all Death Knight specs, frost also uses diseases to deal periodic damage, but diseases also maximize damage on your Obliterate. It is recommended to use 2 slow weapons.
This is the spec I use, it's the optimal PvE dps spec, it maximizes your damage on enemies and adding Necrosis dramatically increases your damage. http://talent.mmo-champion.com/?death-knight#8lP1Q6Z8WaA_G4,awIO3e,12213 To further increase your dps use Unholy Presence, its best for dps since it increases att speed and decreases cool-downs. And of course you should stack hit chance < expertiese < str < crit < haste. Optimal trinkets are ap and crit. Runeforging : MainHand : Rune of Razorice, OffHand : Rune of Fallen Crusader. Using heirlooms isnt recomended, because you cant runeforge them.
In PvP things are a little different, instead of unholy sub-spec you will use blood, mostly for runetap. http://talent.mmo-champion.com/?deathknight#_7z3b23mZK9YV,wkaO3R,12213 Use same runeforging as in PvE and stack same stats. You can use all presences here but still unholy is recommended for dps and frost is when u are crowded with enemies (tanking). Hungering Cold is not used in PvE as it is in PvP because its used for quick escape or just immobilizing unwanted threat for a while. Still Obliterate is your main damage attack and howling blast is your main aoe.
