Reactions

• Multiply (3/Day). When it takes damage while below half its hp max it creates a spectral hound. Spectral hound uses the stats of a shadow except it doesn't have Sunlight Weakness trait and can't make new shadows when it kills Humanoids. It appears in an unoccupied space within 5 ft. of the relentless hound and acts on same initiative as that hound. After spectral hound finishes a long rest it becomes a relentless hound.
