Now the next choice for me is which 5* to use this device on. And I will exclude Specter simply because I have already invested in her.
Looking at the others, Ptilo or Warfarin could be it, giving me a competent healer. Aside from them I'm also eyeing Shamare because she's supposed to be a really good debuffer.
And at some point I will also need a leveled caster... which is ether Amiya or Leizi? Never heard anyone mention Lazy before, so it's probably a case of unpopular or bad gameplay. And then there's not-May in the corner, who I'll get one of these days. I could really use a DP generator...
