Phasewalk is Lilith's Action Skill. It renders her invisible to the enemy, invulnerable to damage, and increases her movement speed. Entering or leaving Phasewalk produces a Phase Blast which has an AoE burst of damage that increases with your level and artifact effects. Entering Phasewalk has a Cooldown period of 36 seconds that starts only after leaving Phasewalk, although Blackout works during Phasewalk in conjunction with Radiance and/or Phoenix.
