Veil of Unbecoming
The ring was forged in a place that predates the Shadowfell, a wound in reality where thought calcified into matter and the first watchers learned to go unseen. It has passed through the hands of seven shadar-kai over four millennia, each of whom wore another's face until the end, their true names erased so completely that only the ring remembers them. It does not grant power so much as restore what was always there: the absolute right to be unknown.
Mechanics
A ring of absolute concealment and psychic dominion that bends perception itself, allowing the wearer to become whoever, or whatever, she chooses while unraveling the minds of those who look too closely.
The Unwatched Face
While attuned to this ring, you are permanently under the effect of a nondetection spell that cannot be dispelled by any means short of a wish. Additionally, you cannot be targeted by divination spells of 5th level or lower, and attempts to scry on you automatically fail. Truesight and other magical sight perceive you only as a humanoid of indeterminate age and appearance, never your true form, never your current illusion.
The Patient Mask
You can cast disguise self at will, with no components required. When you use this ability, the illusion extends to your psychic presence: creatures with telepathy or psionic awareness perceive thoughts and emotional impressions consistent with the form you have assumed. A creature that physically interacts with you or succeeds on a DC 22 Intelligence (Investigation) check discerns the illusion is magical but cannot determine your true appearance. If a creature succeeds on this check, the ring immediately cloaks your psychic signature and that creature must succeed on a DC 22 Wisdom saving throw or forget having doubted you, believing the form genuine until the next time it succeeds on the Investigation check.
Ocular Ruin
When a creature within 60 feet of you targets you with an attack roll or a spell that requires a spell attack roll, you may use your reaction to flood its mind with alien geometries. The triggering attack or spell automatically misses, and the creature takes 4d10 psychic damage and must succeed on a DC 22 Intelligence saving throw or be stunned until the end of its next turn. Once you use this ability, you cannot use it again until the next dawn.
Unraveling Gaze
As an action, you choose up to three creatures you can see within 90 feet. Each target must make a DC 22 Wisdom saving throw. On a failed save, a target takes 8d8 psychic damage and is frightened of you until the end of your next turn; on a successful save, it takes half as much damage and is not frightened. Creatures that fail the save by 5 or more also have their Intelligence score reduced by 1d4 until they finish a long rest. A creature whose Intelligence is reduced to 0 this way is rendered catatonic for 24 hours. Once you use this ability, you cannot use it again until the next dawn.
Shadow Beneath the Skin
Your hit point maximum increases by 30. When you are reduced to 0 hit points, the ring tears open a shadow between planes, you are immediately transported to an unoccupied space of your choice within 60 feet that you can see, you are stabilized at 1 hit point, and every creature within 30 feet of the space you just left must succeed on a DC 22 Constitution saving throw or take 6d10 psychic damage. Once this transportation occurs, it cannot happen again until the next dawn.
DM Notes
This is a powerful defensive and battlefield-control ring designed for a high-level Sorcerer who functions as a hidden, calculating force multiplier. The Unwatched Face is deliberately campaign-disrupting, it shuts down nearly all information-gathering by enemy factions and should be accounted for in any mystery or intrigue arc. The DM should rule that artifacts, deities, or cosmic entities of sufficient power may still perceive the wearer. Ocular Ruin and the emergency teleport on Shadow Beneath the Skin are once-per-dawn, which limits nova potential but means a player who conserves them gains enormous security. Unraveling Gaze is devastating against low-Wisdom, grouped enemies, at legendary level this is appropriate but DMs should note that back-to-back uses across two turns (first after a long rest, then again the next dawn) can trivialize encounters. The Intelligence reduction from Unraveling Gaze is a long-rest recovery, not permanent, watch for it to stack across multiple castings on the same target and clarify it does not stack with itself (take the single highest reduction). The +30 HP is intentionally high to represent the wearer's shadar-kai resilience amplified by the ring; adjust down to +20 if the character is already extremely durable.
