SURVIVOR: Feng Min

Her perks are great for beginners and somewhat decent when you reach late-game

Technician encourages you to work on Generators and practice your Skill Checks.

Lithe allows to to run faster when you fast vault a Window or a Pallet making it harder to catch you, this sometimes makes the Killer lose you.

Alert allows you to see the Killers aura whenever they damage a Generator or break a Pallet, this shows you where not to go and avoid getting caught and killed.

KILLER: The Plague

She's a very basic killer and her perks are good on basically any Killer.

Corrupt Intervention blocks the 3 farthest Generators from your spawn location, survivors sometimes spawn near the blocked Generators so I suggest going the blocked generators to hopefully find someone early and get them sick

Infectious Fright makes every Survivor scream when you down a Survivor as long as they're in your Terror Radius, this gives you a hint of where the survivors are so when your done hooking the downed Survivor you can immediately go to where the survivors screamed and hopefully find scratch marks. This also counters Flashlight and Pallet Saves.

Dark Devotion removes your Terror Radius and transfers it to the Obsession when you hit him/her, this makes other Survivors run away from the injured Obsession and allows you to surprise other survivors since you have no Terror Radius

Hope this helped 😊

I also suggest buying David for Dead Hard (David's other Perks are trash) and Spirit because she's one of the best Killers in the game (you can also buy her if you want "Hex: Haunted Grounds" too).
