Evening,

Having got a large amount of SR tomes from the current events gacha I actually have enough now to 4 star one of my SR Kami's, any advice on which one I should 4 star?

I was thinking a really good support (Beelz or Ramiel) or a healer (Nike) would be the best choice, however I dont know if something different / special / unique happens on a 4 star unlock so wanted to make sure I wasnt throwing away the unlock.

Thanks
