I see alot of conflicting information about the 5 piece set and I want to actually know how to get the full value out of using it? I see people say that spirit needs to be higher in order to get full value and some don't. When I use it so far after a couple hours of testing, my spirit is constantly drained due to lightning storm spam, so with that said am I not getting value from it?

How does this unique work with this specific variant of lightning storm? Is it still worth using them? I have a pair of ancestral legendary gloves that are very good but I also have these gloves and I'm torn on which ones I should use. Does using omnibolt make these gloves less worth it? Or is there something I'm missing?
