Blood Vortex is a vampiric Necromantic Spell (Mental Skill) of the Second Twilight Circle that Scarlett may use to drain Health from multiple enemies and add that damage to her own Health. This skill has four Levels of Mastery. The amount of damage inflicted on each of the enemies (and added to Scarlett's own Health) increases with her Level of Mastery of the Skill, as does the amount of Mental Energy required to cast the spell. The amount of damage also increases with Scarlett's Mental Power Attribute.

If multiple enemies are in range, the full damage is inflicted on each enemy, so the more enemies present, the more total damage is inflicted and the more Health is recovered. Compared to its sister spell, Blood Toll, Blood Vortex has twice the Mental Energy cost and inflicts fewer points of damage in a single opponent, but inflicts more damage when facing multiple enemies.
Blood Vortex is and active Mental Skill. It must first be placed on the game's QuickBar before it can be explicitly invoked. If there is no enemy in range, or if Scarlett does not have sufficient Mental Energy, the spell's icon on the Quickbar is dimmed. Recovery time from the cooldown interval is indicated by partial dimming of the spell's icon.
Scarlett can only learn this Mental Skill after she has learned at least one Level of Mastery in its similar prerequisite, Blood Toll. She must also accumulated sufficient Skill Points and find a suitable Necromancy Trainer. Scarlett can increase her Level of Mastery of this skill by spending additional Skill Points with any Necromancy Trainer.
