The Covenant system for Dark Templars has been streamlined and a number of Covenants merged or removed. There are now a total of 4 Covenants available, 3 innate (Covenant of Pestilence, Covenant of Invulnerability and Covenant of Vengeance) and 1 feated (Covenant of Arms). All Covenants now have a 1 second cast time, so they can be swapped around in combat if needed, but share a 5 second cooldown. All Covenants now share the same stacking order so can be overwritten by another Covenant without you needing to manually remove the currently running Covenant.
Covenant of Pestilence has been converted into a physical mitigation Covenant. It provides a bonus armor % increase, causes attackers to take damage every time they hit you, and attacks against you have a chance of triggering AOE unholy damage around you.
Removed the inherent snare effect from Covenant of Pestilence.
Covenant of Invulnerability has been converted into a magical mitigation Covenant. It provides a bonus protection % increases, and causes casters to take damage every time they land a hostile spell on you. A new rank has been added to this Covenant, obtained at level 35.
Covenant of Vengeance now gives you a weapon contribution % bonus, and attacks against you have a chance of granting you additional weapon contribution % bonus. There is now only a single rank of this Covenant, obtained at level 15.
Covenant of Arms (feated via the Desecration tree) is meant to be a feated replacement for Covenant of Vengeance. It now gives you a weapon contribution % bonus, and your attacks have a chance of inflicting additional unholy damage on the target.
The old Covenant of Death has been removed and turned into a passive ability. Now, when you get this ability at level 80, your Covenants of Pestilence and Invulnerability will become permanently augmented to grant you additional health tap (both physical and magical), while your Covenants of Vengeance and Arms will become permanently augmented to grant you the Blood for Blood buff whenever you or your team makes a killing blow, which grants you significant unholy combat rating for your next 3 attacks.
The Vile Pestilence feat has been replaced with Solid Pestilence. Each rank adds armor to the Covenant of Pestilence, and causes you to gain Blood Seals when you are attacked. This also grants you the new Seal of Yog spell if you don't already have it. Each feat increases the maximum number of Blood Seals you can gain by 4 (4/8/12/16/20).
The Invulnerable Soul feat has been changed and now each rank adds extra bonus protection % to Covenant of Invulnerability. In addition, it causes you to gain 1 charge of Invulnerable Soul per feat point when Covenant of Invulnerability is running, which grants you additional protection. When you are struck with a magical attack, it consumes a charge of Invulnerable Soul, and grants you an Arcane Seal. Your Invulnerable Soul stack will reset to the full amount 10 seconds after you last lost a stack charge. The maximum number of Arcane Seals you can gain is 10. This also grants you the new Seal of Yog spell if you don't already have it.
Seal of Yog - This is a new spell granted by the Invulnerable Soul and Solid Pestilence feats. It consumes the Blood Seal or Arcane Seal stack that you have. The more seals that are consumed when it is used, the greater the power of the Seal of Yog.
When consuming the Blood Seal stack, it increases your maximum health, and heals you for that amount.
When consuming the Arcane Seal stack, it increases your critical rating and causes you to regain mana whenever you perform a critical strike.
