Luminous Scales of Serpentis

These slender, iridescent scales, once part of the body of Serpentis Luminara, shimmer with a strange light. Wearing these scales grants a +1 bonus to AC and advantage on saving throws against being blinded. However, the otherworldly nature of the scales causes the wearer to occasionally experience vivid hallucinations—once per long rest, the wearer must succeed on a DC 13 Wisdom saving throw or become confused for 1 minute (using the effects of the Confusion spell). The scales were harvested by the aberration's own twisted will, as it shed them in a fit of delight for their beauty, hoping to lure in unsuspecting intruders with their allure.
