Improved Icy Talons
Increases the melee haste of all party and raid members within 100 yds by 20% and your haste by an additional 5%.

Patch 3.3.3 (2010-03-23): This effect is now passive instead of being a proc. The self haste buff remains unchanged.

Icy Talons

You leech heat from victims of your Frost Fever, so that when their melee attack speed is reduced, yours increases by X% for the next 20 sec.


Patch 3.3.3 (2010-03-23): The personal haste benefit provided by this talent is no longer exclusive with other sources of melee haste. This will allow death knights to always swing 4/6/12/16/20% faster when Frost Fever is applied. Windfury Totem and the party/raid component of Improved Icy Talons still do not stack.
