If Crows Trap Aid has been purchased, finishing enemies off with a cast of Undertow can send the booby-trapped corpses into other enemies, perpetuating the effects of the Vigor.Against lone targets, this can turn the combo into a long-distance escape mechanism. Enemies distracted by Murder of Crows will be unable to retaliate if the player uses Charge to ram into them.Igniting the crows with Devil's Kiss will set them on fire, causing them to deal significantly more damage and ignite all enemies in their vicinity.Electrifying the crows with Shock Jockey will infuse them with the electrical effect, causing them to deal minor additional damage and stun targets all around them for much longer, also doubling the damage their victims take from all sources, including the combination below.
