Meh, I'm free from some of my finals today, so I'll give my two cents
This honestly all seems like an outlier to me... But I doubt anyone will listen to that...
Also those aren't moons... Not real ones anyways... They don't really look like proper moons, they have like a diamond-like pattern on them, and I have doubts that Reve can properly comprehend and understand the full size of the moon, therefore creating a real one. So I'm extremely skeptical of those being actual real moons that this person made. I mean it's
Don't know where you're getting the diamond stuff from. I see craters. Dorothy/Reve creates real water that can conduct electricity and then make it explode with fire, which gives credence to it being an actual moon.
Lucifero's "World-Ending" and "Bring ruin to the world" stuff doesn't mean much since basically every verse has those kinds of lines and they don't immediately qualify for 5-B off of those statements. You can bring an end to the "Sekai" in any number of ways, many of which don't actually mean nuking the planet or exploding it's surface, so it's loose support that can sorta back up the meta... But that's if there was a solid Tier 5 feat to go off of. Tier 5 for BC right now is supported solely by a bunch of vague, up to interpretation statements that could just as easily be hyperbole to hype up new threats.
We're not immediately qualifying 5-B Black Clover solely because of these statements. We are pairing 3 statements with creation feats, a feat, and a scaling chain. So saying that we can't make 5-B Lucifero because of the statements is redundant because that isn't our argument.
There's also the fact that no other shown feat on screen or statement within the manga itself actually supports the High 6-A feat... I'm not the kind of grouch that complains if a feat solely comes from a statement or two, I understand those statements are just as valid as feats sometimes. But to consider that arcs taking place after the Witches Forest arc hype up Demon Licht cause he can nuke the country, with Lumiere even unsure he can block it, and with this stated feat being the strongest calc in the entire verse that doesn't rely on outside material... It really brings into question the idea that Fana can just vaporize a literal entire ocean just with one attack... Yeah yeah yeah, AOE Fallacy and all that, but all of this is just so hard to accept because it's a bundle of not solid stuff... Everything in the OP is subjective and up to interpretation... I want a solid feat from the actual series itself that's near this level of power, cause like I said before, the best feat this verse has outside of the Databook statement is only Small Country level
Lumiere said, "Even if I block it, the Clover kingdom will..." This is implying that a small fraction of Demon Licht's power would've destroyed the clover kingdom. Because he said even if he blocked it, it would be destroyed. Which means its full non-blocked power is far greater. The narrator has several statements that Demon Licht nearly wiped out humanity, but Lumiere stopped him. This means Demon Licht's blast would've also destroyed the ocean to reach the people that live at the bottom of it, which gives direct credence to the Salamander's feat.
I'm extremely inclined to consider the feat an outlier and I just can't accept this CRT in good conscience
I understand.
But let's recap. Your basis is that the Salamander feat is an outlier. But that makes it hard to be the case because it has two separate feats in the databook of being High 6-A. Both drying an ocean and the 1,000 Ri statement (an objective measurement) leads to multi-continental levels of energy. And let's not forget the high-end of Salamander is actually about 68% to 5-C anyways. This is a feat that was overseen by Tabata, and he approved of it, as shown in the OP. And while I understand your hesitation with the moons, I believe they should be scaled to the moon based on my previous conclusions. Reve/Dorothy both scale considerably above High 6-A characters, and create the real things they visualize. This adds a lot more support to Lucifero's planetary statements. The actual numbers we got him to was simply based on upscaling from Reve, but the statements act as supplementary pieces of evidence to everything else.
I don't think this thread should be thrown out because: Secre saved the day with the magic item that averts the showing of Demon Licht's feat AND the Witch's Forest being protected by a natural mana force field as well as magic from a character stronger than it.
I know this isn't a feat, per say, but Lolopechka makes Mana Zones the size of
entire countries. Characters' actual power is FAR greater than the size of their mana zones.
there is no need to use reverse psychology
