Ring of Ebon Dark

A magical item that grants its wearer several powers, first introduced in the Lilliend-Gazetteer in Quoth the Raven volume 25.

Thrice a day, the wearer can invoke a Dancing Dark-spell. Twice a day, the wearer can invoke a Darkness-spell. Once a day, the wearer can invoke a Deeper Darkness-spell.

Alternatively, the wearer can use a charge from the ring to immediately counter and nullify Light-based spells of the same level, allowing the one casting the light no save to defeat the assault on their magic.
