Power of Blood is a series of special abilities enabled by the Warden's Keep DLC for Dragon Age: Origins. There are two for each base class (warrior, rogue and mage). Note that these abillities will not be useable in Dragon Age: Origins - Awakening. The exception to this will be that Rogues with the Power of the Blood ability will still be able to move quickly while in stealth mode.
Acquisition
To activate the two Power of Blood abilities available to his class, the Warden must drink the Alchemical Concoction found during the Soldier's Peak quest.
There might be a possible way to get a second chance to drink this Vial if you have not drank it during your Soldier's Peak Quest. This requires you to:
- Disable the Warden's Keep DLC
- Force Load your latest Save
- Save the game you just Forced Loaded
- Enable the Warden's Keep DLC
- Load your latest Save
- Replay the Warden's Keep and get your 2nd chance at the Power of Blood spells
[PC Version, the Soldier's Peak will disappear from the map, and there will be no NPC in the camp. Quest is still completed in the journal.]
Spells – Mage
 Dark Sustenance |
Activated Range: Personal Activation: 0 Cooldown: 60s |
A self-inflicted wound lets the mage draw from the power of tainted blood, rapidly regenerating a significant amount of mana but taking a small hit to health. |
 Bloody Grasp |
Activated Range: Medium Activation: 15 Cooldown: 10s |
The mage's own tainted blood becomes a weapon, sapping the caster's health slightly but inflicting spirit damage on the target. Darkspawn targets suffer additional damage for a short period. |
Talents – Rogue
 Dark Passage |
Passive | Tapping the power of tainted blood makes the rogue more nimble, able to move more quickly while using Stealth and more likely to dodge a physical attack. |
 The Tainted Blade |
Sustained Upkeep: 40 Fatigue: 5% Cooldown: 5s |
The rogue's blood gushes forth, coating the edges of weapons with a deadly taint. The character gains a bonus to damage determined by the cunning attribute, but suffers continuously depleting health in return. |
Talents – Warrior
 Blood Thirst |
Sustained | The warriors own tainted blood spills in sacrifice, increasing movement speed, attack speed and critical hit-chance. For as long as this mode is active, however, the warrior suffers greater damage and continuously diminishing health. |
 Blood Fury |
Activated Activation: 35 |
The warrior sprays tainted blood in order to knock back nearby enemies, which they may resist by passing a physical resistance check. The gush of blood, however, results in a loss of personal health. |
