The Doctor and Feng Min are some of the first characters to be added to Dead by Daylight, but neither show their age; the Doctor remains a fairly powerful mid-tier killer, while Feng Min remains one of the most popular survivors in the game. The Doctor is a terrifying doctor-gone-mad-scientist, with a permanently smiling mouth forced open by a brace. But has his power aged as well as his design?
The Doctor's power, Carter's Spark, allows him to manipulate the sanity of survivors throughout the course of the match. The Doctor has both a long range and short-range attack.
Both the long-range and short-range versions of the attack induce madness in survivors, causing them to experience hallucinations and impairing their ability to evade the killer. This power adds a psychological element to gameplay, as survivors must contend not only with avoiding The Doctor but also with the effects of their escalating madness.
The long-ranged attack that The Doctor has, though, is the real star of the show. Using this attack will alert him to the locations of survivors all over the map, causing them to scream when the attack hits them.
By virtue of the strength in his power's tracking, The Doctor rarely needs to rely on tracking perks, freeing up several potential slots in his loadouts. For beginners, finding hiding survivors and determining survivors' potential locations is often one of the hardest elements of gameplay, so The Doctor is a great pick.
Along with The Doctor, the Spark of Madness chapter includes Feng Min, who comes with her own three perks. None of them are particularly strong - in fact, Technician may be one of the weakest perks in the game, though it's helpful for beginners - but she's one of the game's most popular and iconic characters, with a host of cosmetics for players to choose from.
