This will increase your Frost damage by 30%. This is a rather big number and this is needed if you're specing deep into the Frost tree and will be using a lot of Frost abilities in your rotation.Increases your chance to hit by 3% with one-handed weapons and increases damage done by your offhand by 15%. Well this one is a tough one. WOW GOLD players can skip it for most occasions unless to-hit is something you desperately need.Whenever someone's melee attack speed is reduced with Improved Icy Touch (and Frost Fever) then this ability will increase your attack speed by 20% for 20 seconds. Haste is generally not that great for a Death Knight but is still a pretty high increase in DPS with a big 20% number.This is an instant ability with a 3 minute cooldown. It turns you undead (making you immune to Charm, Fear, and Sleep) and gives melee attacks a 25% chance to miss you for 15 seconds.There is little reason at all not to get this because of the low cooldown and high chance attacks will miss you. In PvP this can help turn the tide against a Warlock or Priest while in PvE this can help tremendously with tanking or even soloing.Grab it.Increases critical strike chance by 3% and will give you a 100% chance that your Obliterate will do damage without consuming a disease. Obliterate is awesome, critical strike is awesome, and not consuming a disease can mean the disease can last longer on the target or your DPS/rotation won't suffer so much if your next disease misses.
