Yes. It's not a braindead-slap-on-any-servant-and-get-good-results 50% battery+effects, but I see it good for someone with, probably a buster NP and some arts cards to make full use of the NP gain. I anticipate it being good for Super Orion to get his NP more often and increase his buster power; in this way, you wouldn't have to worry about the CE giving extra crit up (as many CEs do) and running into the crit ceiling.
