Sorcery developed by a certain surreptitious sorcerer at Vinheim Dragon School.
Masks noises of the caster and prevents fall damage.
Their mastery of this sorcery alone allows Vinheim spooks to demand handsome payment for their services.
Prevents non-lethal fall damage and silences the player's footsteps and rolls.
Can be used to circumvent obstacles in your path by jumping down to places that would normally kill you.
