The Dwightcrow Charm was introduced in celebration of the Halloween season, a perfect time to play Dead by Daylight. Behaviour Interactive has a lot planned for October, even releasing a full roadmap of sorts for the Halloween event.
As described in the developer update, "Survivors will be able to bless a totem to change it into a Boon Totem and these blessings are designed to offer comfort to the Survivor Team, a small safe haven. However, unlike a Hex Totem, the Killer can also quickly interact with the created Boon Totem to completely remove the associated blessing, once again turning it into a dull totem, they will also be able to hear the Boon Totem when in its range. Each Survivor can only have one Boon Totem active at a time. This Boon Totem will combine the effects of all of their equipped Boon perks."

But for those looking for a cool cosmetic of sorts, Behaviour has given players a free charm. Simply use the code DWIGHTCROW on PC or console and you'll receive the charm. There is a time limit as it's only available between Oct. 1 through Oct. 31.
Players can also enjoy The Fine Dining Collection which is in the store for 1,080 Auric Cells. It costs $4.50 for 500 cells and $8.99 for 1,100. So the skin isn't cheap.
