Lots of talk about diamonds and spell slots and for funsies/curiosity, I looked up how tapped out Fearne was at that moment. In this long, no good, pretty rotten day, she used:
2nd lvl heat metal on FCG when he went robocop
3rd (?) lvl cure wounds on FCG to revive him after going robocop (level uncertain. rewatching the scene, Ashley grabbed two dice and then rerolled another, so it looks like a 3rd level, but this is also speculation.)
1st lvl detect magic when they were planning how to extract Treshi
3rd lvl hold person at the beginning of the fight with Otohan
1st (?) lvl cure wounds on Orym to pick him up in the fight (again uncertain, but the roll was low enough that if it was a 2nd lvl she rolled really bad)
3rd lvl revivify for Orym
Fearne would have had two 1st level slots and two 2nd lvls.
Either way, I prefer how everything played out. Not everything needs to be done optimally and in this case, regardless of whether it was spell slots or diamonds, I like the repercussions of this PC death. It doesn’t feel permanent given that they have a lot of options for them to use to bring her back but it does give weight.
Edit: No 4th lvl because I forgot she multiclassed.
