Baleful Glare. When a creature that can see the eyes of Yuri's severed head starts its turn within 30 ft of her, Yuri can force the creature to make a DC15 Wisdom Saving Throw if Yuri isn't incapacitated and can see the creature. On a failed wsave, the creature is frightened until the start of its next turn. While frightened in this way the creature must move away from Yuri, and can only use its action to dash. If the creature is affected by the dullahan's Deathly Doom trait, it is restrained while frightend instead. Unless surprised, a creature can avert its eyes to avert its eyes again. If the creature looks at Yuri in the meantime, it must immediately make the save.
