I admit that I was a bit vague.
Yup, I ignored the NP gauge they provide to themselves.
For farming that only comes into play if there is a spare K-scope or in Reines case a MLB.
My example with AD assumed they had a self battery.
It depends on the servant so someone with a large 30% like Arash/Spartacus would require just a 50% CE.
On the other hand if they haven’t got a battery but hits hard enough like Fran then she’d be fine with a non-mlb K-scope.
Gilfest might be a good example for my thoughts.
This is a valid non-gacha team and it should work for one round this year and next.
Paracelsus(50 ce), Arash (AD), Spartacus (event CE), Waver, Shakespeare
Paracelsus: 50(CE)+55 (battery)
A team like this is beyond Reines capabilities.
For Nerofest/Gilfest the most available option to clearing the final wave is relying on Spartacus and he requires the full 50%.
The reason I rate her lower is that she isn’t as flexible as Waver.
You either need MLB K-scopes, servants with batteries or a secondary np gauge provider.
The problem with additional teamwideNP providers are that they are rare and the more accessible options will drop the damage output.
There are 3 that comes to mind:
Chen Gong, has only a 10% gauge so wouldn’t work for this example.
Asclepius has a 20% but 0% offensive benefits, downside is that he is storylocked.
Helena(SR ticket) has a 20% battery but only a 20% buff so in this case a drop by almost 20% buster compared to Shakespeare in this example.
