 * Malus Phasmatis (Perdition Rock)

Related Skills

 * Throw Dirt
 * Ineptitude (Elite)
 * Blinding Flash

Usage

 * This skill is much more useful defensively than offensively. Due to its touch range, it is rarely a good idea to plunge headlong into the fray with your fragile Mesmer's armor with the intent to blind your target, but it can be a complete lifesaver if a melee user (be it an enemy Warrior or a Bladed Aatxe) decides to feast on your squishy flesh.
 * For Mesmer/Necromancers or Necromancer/Mesmers, the fact that this skill blinds you as well can be used to your advantage if combined with skills which transfer conditions, such as Plague Touch or Plague Sending.
 * For Me/R or R/Me, consider using this in tandem with Antidote Signet to remove the blindness on yourself.
 * Combine with necromancer condition transfering skills to move the blindness from yourself to another foe, blinding two foes at the same time.
 * As with most spell casters, blindness is not that much of a disadvantage to those that cast spells. Since blindness does not affect casting spells, a mesmer will still be quite affective versus those that rely upon sight (assassins, Rangers, Warriors).
 * Combine with Mantra of inscriptions or Mantra of signets to use Signet of midnight more often.
