The Beacon Greatward

Powered by the now-empty prison of the Scar That Abides, the town is ringed by an array of wards, all configured to keep out fiendish influence and block the entry of demons into the town.    The Greatward functions as the Umbra's Veiled Circle spell. In addition, any creature which completed a long rest inside the ward in the last 24 hours can invoke the ward when they fail a saving throw within it. When invoking the ward, the creature may immediately re-roll the failed save, taking the highest result. After doing so, they cannot invoke the ward again until they have completed a short or long rest.
