Tale of the Light's Trick

"A tabaxi, much like Trick, is stitched onto the sash. She holds up a lantern, its blue-purple light shining into tendrils of shadow that recoil away from her."

When this is selected as your Spark of Inspiration, you become immune to the frightened condition.
Additionally, you can cast the Dancing Lights cantrip at will. The sash counts as the spell's focus. Light cast by this spell is able to overcome magical darkness created by spells of 3rd level or lower.
