Diva is a Tier One talent in Lilith's Controller skill tree. It increases the capacity of her shield by 5% for every skill point put in it.
Additional levels may be acquired through the use of Class Mods
This skill works well with Girl Power, as it will indirectly increase the amount of shield recharged per kill.
This skill will deactivate when in a vehicle. Your shield will be dropped to base when you get out. Class Mods that affect shield capacity are unaffected. Be sure that the potentially lower shield won't hinder you when exitting a vehicle.
