Lilith

Once human, Lilith was turned into one of only six Sirens, a group of people with unbelievable powers who have been touched by alien technology. She comes to Pandora in search of another Siren, in an effort to find out more about herself.

Gameplay
Lilith is essentially the mage of the group, using her Siren powers to support the group and attack the enemy and can also use her Elemental weapons to attack the enemy. Lilith could also be treated as the rogue of the group with her Phasewalk ability turning her invisible for a short time allowing her to sneak around at an increased speed, her Assassin skill tree giving her more melee/critical damage and her Controller skill tree giving her the ability to daze which can be helpful if you are playing alone.

Her Elementalist tree adds bonuses for weapons that employ static, incendiary and corrosive damage.

Active Ability

Lilith's skill is called Phase Walk, which lets her turn invisible to enemies (but not to teammates to which see turn a translucent pink), move much faster, and cause a damaging shockwave upon entering and exiting. Gearbox co-founder Randy Pitchford describes it as "kind of like when Frodo puts on the ring, except that when she takes it off she can kill everything around her with a shock wave nova effect." This effect can be altered by using unique artifacts that can add elemental damage to the "shockwave".
