This Blessing was created by the Witch, Angelica Frost of House Rivers, who later became know as the "Blood Angel". Her elegant but somewhat messy methods made her someone to be admired but feared among the many followers that worshipped that House.
Bloodlust allows your Ruin Flare to deal an additional 1d8 bleed damage to your target. As long as your target is bleeding, you gain a +10 bonus to your movement speed and a +2 bonus to your attack rolls against that foe. The bonuses from this Blessing do not stack. To stop the bleeding, they must be healed magically by a person that has a caster level equal to or greater than your own or with a Heal check of 15 + your CHA modifier.
