Perks that work with the Knight's Guards revisited

• A Nurse's Calling - Partially - The guard helps you by injuring the survivor.

• Bloodhound - Yes - The guard injures the survivor and Bloodhound activates.
• Call of Brine - N/A
• Coulrophobia - Partially - The guard helps you by injuring the survivor but, if they heal, they must be inside the Knight's terror radius.
• Dark Devotion - Yes - Injuring a obsession with a guard will transfer your terror radius.
• Dead Man's Switch - Partially - A guard can help you push off the survivor from the generator to activate Dead Man's Switch more easily.

• Fearmonger - Partially - You can use the guard to force a survivor off the generator and make them run, stopping the Exhaustion timer.
• Forced Penance - No - Guard hits does not trigger Protection Hits which could be awesome if it did because survivors can take the hit from whoever is being chased by a guard.
• Gearhead - Yes - The Guard injures the survivor, activating Gearhead.

• Hoarder - N/A
• Hysteria - Yes - If a guard puts a healthy survivor into the injured state, Hysteria activates.

A Injured survivor that is affected by Gift of Pain is good because they lose healing progression by being chased by a guard and mangled to leave a lot of blood puddles behind for the killer to track.

Tips

• Haemmorhage is great for you because the guard can chase the injured survivor and they will lose their healing progression if they have any.
• Mangled is great for you because the guard forces survivors to run, leaving a ton of blood behind for you to track down.
• Exhaustion is great for you because the guard chases the survivor with exhaustion and that will stop the survivor from losing the exhaustion effect.
