Gem of Brightness

Magic Items Dungeon Master’s Guide

Light in a 30-foot radius and Dim Light for an additional 30 feet. This effect doesn’t expend a charge. It lasts until you take a Bonus Action to repeat the command word or until you use another

Word. You expend 5 charges and cause the gem to flare with intense light in a 30-foot Cone. Each creature in the Cone makes a saving throw as if struck by the beam created with the second command word. When all of the gem’s charges are expended, the gem becomes a nonmagical jewel worth 50 GP.

Fear

Spells Player’s Handbook

Each creature in a 30-foot Cone must succeed on a Wisdom saving throw or drop whatever it is holding and have the Frightened condition for the duration. A Frightened creature takes the Dash action

and moves away from you by the safest route on each of its turns unless there is nowhere to move. If the creature ends its turn in a space where it doesn’t have line of sight to you, the creature makes a Wisdom saving throw. On a successful save, the spell ends on that creature.
