Dead by Daylight's Blood Moon Collection comes with several free, earnable cosmetics, as well as several purchasable ones. While The Oni and Elodie's event costumes are earned through the event tome and a variety of other outfits are available in the in-game store, you might be curious about how to get The Knight's Bloodwyrm helmet.
To get the Bloodwrym cosmetic for The Knight, all you'll need to do is purchase any number of Auric Cells between 18 March and 31 March 2024. You'll then immediately receive the new Bloodwyrm helmet for The Knight.
Unfortunately, unlike some of the Blood Moon Event's cosmetics, there's no way to earn the Knight's new helmet for free. Instead, you'll have to spend money on Auric Cells to get this cosmetic. The helmet is also just that - only a helmet - and isn't part of a full set, though thankfully you can mix-and-match it with other cosmetic pieces for The Knight's torso and weapon.
The Knight's Bloodwyrm helmet is a nice little bonus reward for buying Auric Cells in the next few weeks. It's one of many costume pieces that are available during the Blood Moon event, so be sure to check them all out in-game!
