The Wolves are enemies that make an appearance in Lost In Vivo's Midnight mode. There are three variations, each sporting a different design.
The wolves take and deliver considerably more damage the higher up the chain of command you go, with the basic Wolf obviously being the weakest, and the Demon Wolf being the strongest.
Each wolf can more or less be dealt with in the same way, as long as the player understands what they are doing:
Close the distance between you and the wolf whilst blocking, and after blocking their first attack, be certain to swing your sword with reckless abandon to slay the wolf as quickly as possible. Running away is not an option in most situations, as the wolves are very fast and attempting to heal while one is aggressive toward you is less than ideal.
Try your best to avoid encounters with multiple wolves, and train if necessary.
