The Lords of Midnight
The ring creates a 5’ radius of protection (+2 bonus vs Saving Throws and to AC) from a chosen alignment around the ring (wherever it is placed). The magical protection operates while moving or still. The ring provides protection for 20 minutes, usable three times per day.
The three Rings (Primus, Secundus, Tertius) can be used together.
