Wondrous Item, legendary (requires attunement)
Sensorium Stone
Wondrous item, legendary (requires attunement)
A smooth, heavy crystal orb pulsing with a faint glow. It traps a dense fog of memories captured by the Society of Sensation. These stones allow you to completely relive a concentrated rush of another creature's lifetime of experience and training, but the process can affect a character’s psyche.
When you complete the attunement process, you instantly absorb its recorded memories, advancing to the next character level (or gaining an Epic Boon Feat if at level 20). Subsequent uses of this benefit in the same Tier of play have no effect.
Upon gaining the level, your attunement ends, the stone becomes dim—turning into a normal sensory stone—and the psychic stress knocks you Unconscious (unable to be shaken or damaged awake). You must make a DC 16 Wisdom saving throw, remaining unconscious for 1 minute on a success, or 1d6 minutes on a failure (repeating the save at the end of each turn to wake up early). When you wake up, you remember your abilities but completely forget the other party members and everything that happened right before using the stone. Treat this amnesia as a Mental Stress effect.

Posted Oct 6, 2026The Sensorium Lore Annex
The multiverse of Planescape is measured not by physical distance, but by the weight of raw experience. The Society of Sensation (commonly known as the Sensates) believes that existence is defined solely by what a mortal soul has tasted, felt, and endured. To catalog the cosmos, their mages created Sensory Stones: crystalline orbs engineered to record, store, and playback raw shards of consciousness. While basic stones are kept stable in the Public Sensorium library within Sigil’s Civic Festhall, the rare and powerful variants found scattered across the dangerous Outer Planes capture entire lifetimes of concentrated training, marcial expertise, and cosmic epiphanies.

Posted Oct 6, 2026Wondrous item, Uncommon.
This small, smooth stone contains the essence of a single experience.
As an action, you or a willing creature you designate can touch the stone and experience the sensation as if it happened to the designated creature. The illusory experience is fleeting and harmless, however real it might feel in the moment.
Record Sensation. You can use your reaction to record a short sensation lasting no longer than 6 seconds experienced by a creature of your choice within 30 feet of yourself, infusing the essence of the experience into the stone. This replaces any sensation already stored within the stone.
Siphon Sensation. As a bonus action, you can draw on the stone's magic to end the charmed or frightened condition on yourself, destroying the stone in the process.
