The third in-hub item, Death’s Dastardly Cape, is available to obtain in the ongoing Roblox The Haunt 2024. Like previous in-gear items, this one is also tied to a small quest that you need to participate in and complete in order to obtain the item. So, here is a quick guide explaining the entire process.
How to Get a DEATH CAPE ITEM!! | Roblox Haunt Event
Death's Dastardly Cape artifact is basically hidden in one of the many mirrors present in the Hall of Villains. So, all you have to do is reach the location and check each of the mirrors available in the room. If you don't know where the Hall of Villains is, just go to the right from the entrance of the mission and follow the route to find it on the right side.
Once you check the first mirror, the mirror will display some message saying "You can barely feel the artifact's presence" or "The artifact feels closer than last time… but it's still far away", indicating that the artifact is far away from the current mirror's position. So move a little far away from this mirror and try again. If you get a message like "The artifact feels closer than last time… it must be ready", then you are going in the right direction and you can find the artifact next to it or very close to it. Otherwise, you are still far away and need to go in another direction.
Use these clues and try to get to the mirror holding the Artifact. If you find the right mirror, you will get the message "I think the Artifact is here." You will get the Artifact directly from the mirror.
