Didn't Karna also display absurd healing powers when he made it through Vlad's internal impalement shenanigans?
I think surviving being impaled by from the inside by Vlad's stakes, then removing it by circulating fire through his insides(which he is not immune to) and then wounding Vlad and almost killing him immediately afterwards is a pretty notable feat.
I also don’t think it was supposed to be a demonstration of healing powers so much as, I dunno, determination? Or grit? I guess?
True, but I think McJon is referring to something more specific to Karna. It's less "I can just heal these wounds" and more " 'tis but a scratch".
So does Scathach perform well enough to take a few lives before jobbing? Or does she straight out job from the start?
The only stuff she has to hurt him are unelaborated on runes and Gate of Skye. The latter seems impressive, but then you remember how Herk walked into the underworld, beat up its dog, and walked right back out. Also how Cu Alter Falcon Punched Scathach straight into her own NP when she tried to suck him off.
Grail-boosted Cuzilla.
Herk yeeting himself out of Tartarus counts for something though yeah.
I remember hearing Cu could rune boost Gae Bolg to kill Herc, so Scathach could probably do that too, but I'm sure it'd only work once.
I'm pretty doubtful about her being > Cu at all. FGO powerlevel is not representative of anything, she might have taught him but compared to him she's a nobody.
Cu's training is hardly the sum of his ability either.
Cu is fighting in a party and has Charlie/Hakuno/whoever else present for backup in Extella Link. None of those fights are ever 1 v 1. Scathach is called stronger than Cu in a lot of places. Pretty explicitly in the KnK event where Cu admits she massacred him and like 20 other heroes in their graduation exam. I don't think it's important here though. She doesn't have a way of roasting all 12 of Herc's lives, and Gate of Skye can be interrupted.
Or she boosts her spear, trapping Herk and then she Gate of Skye's him
I'd say we don't know enough about her special runes or Gate of Skye but while I do think Herk wins more often she's not exactly an easy fight
