A Blood Oath incantation, shared from the Lord of Blood's power. Releases a swarm of bloodflies before the caster to assault foes. The vile swarm deals damage and builds up onset of blood loss. This incantation can be cast while in motion. The new palace of the Lord of Blood lies in a swamp of festering blood, and these flies are said to spawn from excrement in that land.
