Nagi's luck is actually not that bad, she starts out with 10 and the highest crit she has to face is 16, so she only requires 2 goddess icons + rainbow potion or luck bond
the reason I used her is because I really wanted someone who could oneshot fire dragons in chapter 23
the options I saw were either make a mega dragonpike forge or give Nagi a couple statboosters (needs 2 energy drops too for the kill), and she ended up being the far cheaper option.
she can kill the two immediately next to your starting position on turn 1 and then another one on turn 2, which is amazing value considering they require 2 actions to kill reliably for literally everybody else
