The Enigma Order

General
Due to significant talent changes, all death knight talents will be reset for players.

Blood Skills
Blood Strike: The bonus damage this ability receives from diseases on the target has been increased to 50% per disease.

Frost Skills
Chains of Ice: Now reduces movement by 95% instead of 100%. The main effect of this change will be that targets of Chains of Ice will not have to re-issue a movement command to continue moving.
Frost Presence: 10% bonus health reduced to 6% bonus stamina.
Frost Strike: This ability can now be dodged, parried, or blocked. Weapon damage bonus reduced to 55%, down from 60%.
Icebound Fortitude: Cooldown increased to 2 minutes.

Blood Talents
Dancing Rune Weapon: This ability now has a fixed duration of 12 seconds (which can still be modified by its glyph) and a fixed cost of 60 runic power.
Veteran of the Third War: Stamina bonus reduced to 1/2/3%.

Frost Talents
Blood of the North: Reduced to a 3-point talent. Increases Blood Strike and Frost Strike damage by 5/10/15%. There is now a 33/66/100% chance whenever you hit with Blood Strike or Pestilence that the Blood Rune will become a Death Rune when it activates.
Lichborne: Duration reduced to 10 seconds, and cooldown reduced to 2 minutes.
Threat of Thassarian: New 3-point talent. When dual-wielding, your Death Strikes, Obliterates, Plague Strikes, Blood Strikes and Frost Strikes have a 30/60/100% chance to also deal damage with your off-hand weapon. Off-hand strikes are roughly one half the effect of the original strike.
Toughness: This talent now grants 2/4/6/8/10% armor instead of 3/6/9/12/15%, placing it in line with similar abilities of other classes.

Unholy Talents
Desecration: This talent has been reduced to 2 points for 25/50% snare and no longer increases damage done by the death knight. It has also been moved one tier earlier in the tree and its spell effect has been made more transparent.
Desolation: New talent. This talent is in the position formerly occupied by Desecration. It causes Blood Strikes to increase all damage the death knight deals by 1/2/3/4/5% for 12 seconds.
Scourge Strike: Weapon damage bonus reduced to 40%, down from 45%. Damage increased by 10% per disease on the target, down from 11%.
Summon Gargoyle: The gargoyle now flies lower to the ground, making it susceptible to melee attacks. This ability now has a fixed duration of 30 seconds and a fixed cost of 60 runic power.
Unholy Blight: This talent has been redesigned. It no longer deals damage to nearby targets. Instead, when you deal damage with Death Coil, the target will take periodic damage for 10 seconds equal to 30% of the damage done by Death Coil. This damage accumulates in the same way as Ignite and Deep Wounds.
