Ioun Stone of Moonsilver Chronos
- Wondrous Item, Legendary
- Requires Attunement
A perfectly smooth, iridescent sphere of polished moonsilver, this stone subtly shifts colors, reflecting the phases of the moon and emitting a faint, rhythmic ticking sound that only you can hear. It seems to bend the flow of time around it. Moonsilver is associated with chronomancy and the distortion of time.
While this stone orbits your head, you have advantage on Intelligence (Investigation) checks made to discern illusions or temporal anomalies. Once per day, when you or a creature you can see within 30 feet of you makes an attack roll, ability check, or saving throw, you can use your reaction to force that creature to reroll the d20 and use the new result.
