Lian stepped into the cave, the torch held as a shield against the dark. His order had sent him after the lair of a nameless specter; hardly a mission for a newly-titled paladin, but times being what they were….
Just as the outside sunlight faded behind him, his torch was doused by a blast of cold air. He briefly fumbled with the torch before dropping it entirely, clutching his sword in both hands instead. The shadows deepened in front of him, but he treads bravely forward. As the chill of death ran down his spine, like a foot treading on his grave, the dark revealed a distant point of cool, arcane light.
Pushing himself toward the light, Lian finally came to an open chamber filled with empty scroll shelves around a weathered desk. At its center lay a letter, its ink still fresh as he read it.
At the entrance to the room, an unnoticed patch of shadow detached itself from the rest and moved silently toward the mouth of the cave. As the sunlight touched the shadowed form, it became a man like any other, crowned with a simple, silver circlet. He hoped his words rang true to the young invader and prayed that their paths wouldn't come to cross again.

While wearing this dark silver circlet in dim light or darkness, a smoky mantle of shadow covers your head like a dark hood. While covered in this way, you can move through creatures as if they were difficult terrain, regardless of their size, and you have advantage on Dexterity (Stealth) checks. If you end your turn in another creature's space, you are shunted to the last unoccupied space you occupied, and you take 1d10 force damage.

Wraith's Ensemble. Dying doesn’t end your attunement to this magic item. In addition, if you’re attuned to three items with this named property, you treat bright light (but not sunlight) as if it were dim light or darkness for the items’ various properties, and you can use a bonus action to reveal or suppress one or more of the items’ visual effects. While an item’s visual effects are suppressed, you don’t benefit from that item’s other properties.

Notes: Advantage: Stealth, creature
