Common

Common In darkness, the unsheathed blade of this sword sheds moonlight, creating bright light in a 15-foot radius and dim light for an additional 15 feet. This silver blade is forged to resemble a long tentacle that twists out to a sharp point.

The nereid wears a mantle of silky cloth the color of sea foam, which holds the creature's spirit. The mantle has an AC and hit points equal to that of the nereid, but the garment can't be directly harmed while the nereid wears it. If the mantle is destroyed, the nereid becomes poisoned and dies within 1 hour. A nereid is willing to do anything in its power to recover the mantle if it is stolen, including serving the thief.
