Blood Surge is an advanced vampire power that bursts a target from within. It deals big area damage, and even more to bosses, which makes it one of the strongest night abilities you can get.
It detonates the target's blood, damaging everything around them. Bosses take much more damage from it than normal enemies, so save it for big fights.
