Transmogrifying Gaze

When this unit makes a Transmogrifying Gaze attack, choose an enemy unit within 10". Roll a dice for each model in the attacking unit; for each roll of 1, a Sepulchral Stalker has caught a glimpse of its own reflection and the attacking unit suffers 1 mortal wound. On a 2 or 3 the target unit keeps its eyes shut and nothing happens. On a 4 or 5 the target unit suffers 1 mortal wound as it briefly meets the Stalker’s gaze, but on a 6 it suffers D3 mortal wounds as it foolishly stares into the Stalker's eyes and crumbles to sand.
