Limelight raises the respective party member's chances of being targeted by enemies for five turns. It does not stack with itself. If Limelight, Spotlight, Taunting Aura, and Concealment are used on the same target, the last one used will override the rest. If the user is incapacitated, the effect would be halted until they are revived. Enraged foes ignore the effect of Limelight.
It can even influence enemy skills that are programmed to target a particular party member, such as Laevateinn and Piercing Strike, which is normally set to attack the protagonist and a designated target, respectively.
