Increase your attack speed
Increases your chance to hit by 3% with one-handed weapons and increases Entropiauniverse ped damage done by your offhand by 15%. Well this one is a tough one. You can skip it for most occasions unless to-hit is something you desperately need. Whenever someone 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.
