"she easily wipes any foes she has whenever she decides to get serious"
Any foes she has who are scrubs. She didn't have an easy time against Solitar AT ALL, she even needed the assist of Fern to finish her off, and she lost to Macht in the past. Her track record versus top tier opponents shows she doesn't have an easy time when facing off against them at all, only against Aura because she was stupid (Frieren says she would be in trouble if Aura simply decided to overwhelm her with numbers instead of using the scales). Qual doesn't count since he got power creeped by the story
Most of those things seem to be more that she is holding back. Which was established as canon in both scales-arc, flashback-arcs, and hairy-arc.
"hairy-arc arc" okay, what is that supposed to mean?
There was an arc about them doing a dungeon as an exam, proctored by hairy girl, and having heavy focus on hairy girl. Hence, hairy-arc arc.
"she is absolutely godlike when compared to anyone but her own disciple" Frieren JUST got NEG DIFFED against an old, semi-retired shadow warrior prior to us entering this arc, did you forget about that? please don't come at me with "she was holding back and only lost so Stark and Fern could gain experience" BS, because in the following chapters Frieren OUTRIGHT says their lives were hanging by a thread (chapter 126, there was absolutely no reason for Frieren to be lying there).
Not "neg-diffed" at all. Frieren didn't even
do anything - and we have prior seen it to be well within her capabilities to wipe that scrub in that kind of scenario. More likely she just held back to let her kids gain xp. But since you don't accept that explanation, then coming up with one you do will be your own homework. At the very least we know from other arcs that she could easily have handled the guy if she decided to.
And before that, she got neg diffed against Grausam's illusion magic (had to be saved by Heiter and Himmel). And more, in this arc she also admits she can't even IMAGINE herself defeating Serie at all, so one more person to the list.
She does have her weaknesses yes. I never said she was invulnerable. Just that she easily wipes any human scrubs.
Against demons she can likely be challenged, and same for other long-lived races like the elves. Even genius human mages might grow to challenge her, though so far only fern is depicted as getting close. Personally I think Cut-girl (HM-slave girl?) also stands a chance, at least if allowed the first attack.
I advise you to reread chapter 126 of the manga, where the author takes the time to explain the importance of a warrior in a party and how ANY highly skilled warrior could kill Frieren with ease if they were to attack at close combat in a surprise attack
Yes, again, she has weaknesses. Though her detection is one of her best skills, so her getting surprise attacked would be surprising. Also extremely quick at casting spells, and has shown that when given even a fraction of a second to react, she does (just look at hairy-arc arc's final bossfight).
I advise you to reread ch125 where we see her notice the attack before he even entered the door, and she even has several panel's time to see him stand in the door-frame before she allows him to approach and restrain her.
Even then though, that guy was not a scrub like these guys are (ancient assassin), and actually managed to (reportedly, but X to doubt) beat her mana detection. So he had a chance if she hadn't noticed the attack anyway.
In this very chapter (132) we see Frieren being hesitant and deciding to call Stark for him to be at her side before she went to talk with the merchant dude, due to the fact that she was suspicious he could be a warrior and she would need Stark there to guard her in case of an attack at close combat
I never said she was stupid. Always good to have a warrior backup instead of growing arrogant. Outliers do exist (particularly among insane mages), and she isn't yet aware that these guys are truly scrubs. Though in this case it felt more like she was planning to let stark take the warrior role either way, because she tends to do that.
"frieren has already proven stealth to not work against her at all"
the same frieren who almost got killed against an old semi-retired shadow warrior who exceeds in stealth? lol.
reportedly*
In this chapter we instead sees her sniffing out anyone with blood on their hands/hair despite it being long past and cleaned. and we already know she is stellar in detection (magical and otherwise), so it would need to be something really out-of-the-norm to truly bypass her mana detection. And indeed, said priest
did get detected before he even entered the house.
I think we should take what Frieren says seriously instead of doubting it just because the idea that the MC could potentially be defeated bothers some people. Otherwise you might as well just call her a pathological liar since none of what she says holds any weight to you guys.
I can take it seriously when it doesn't actively contradict other scenes in the manga, but when it
does [contradict], I label it as "granny giving younglings xp" instead of "plot hole". Because it is no fun if you assume everything is the latter, and for all I know author might intentionally be doing the former.
