It works on the extra, not on the NP. The attack up portion should work on the NP though. (The skill gives two buffs in the bar, first is the double hits, second is the attack up. Just for clarity, when the double hit portion is active all hits do half normal damage but there are twice as many so damage is the same. It is mostly good for allowing her to generate a bunch of stars and NP easily. My rule of thumb is never to use it unless I am doing a brave chain and starting off with either a quick or an arts so I benefit fully from the multiple hits. The skill works really well with np gen up and star gen up CEs due to the nature of how those stats work, but honestly you're best off with some combination of starting NP, buster up, NP damage, and crit damage. Joint recital, Victor from the moon, Limited Zero Over, First Sunrise, and Demonic Bodhisattva are all good.
