[Scream) A skill that produces effects through an emitted sound. Bats' ability to see things through their cries and special sense of hearing (or at least, this is how it is commonly interpreted in Lambda, though it is actually sonar), the effects of Mandragoras' cries and Banshees' screams come from this skill. Because Vandalieu uses this skill simultaneously alongside the Soul Break and Mental Encroachment skills, in addition to dealing damage to Mana and the sense of hearing in a wide radius, he is also able to perform an attack that causes its victims to die a most terrible death in insanity if they lose the mental battle with themselves. It can also simply be used to make one's voice travel further, without losing any clarity. This allows the user to perform a speech (without the need for a megaphone or microphone).
