While the spell appropriately boosts the health and stamina of undead, Daedric, and automaton targets, the spell effects for the marksman, one-handed, and two-handed boosts are not duplicated with special effects that work if the player has the "Master of the Mind" perk and the target is undead, automaton, or a Daedra, as is the case with other Illusion spells. Hence, this spell is the only Illusion spell which fails to work properly on all targets with that perk taken.
