Why does level 4 have a level up bonus of 2000?

If we considerider the War Game of MS 8 & 18 as Mirror of each other & look at the similarity existing between Bell vs Ottar & Bell vs Hyakinthos. Bell after the last status update he receive from Hestia must have the stat equivalent of a low level 6 (except for agility & magic, the former being higher & the later being lower)

I also made some calculation based on Season 3 fight, Bell needed to have most of his stat at D rank at Level 3 to be the raw equivalent of a level downed Dix, considering the final status Bell has at level 4 was far above the previous by a range (except for agility stat who saddly has decreased by 35 point) between 242-375 points for each statistic so to redo the same above my current level raw ability that Bell do against Dix, he would need most of his stats to be at F or G which was the case after Hestia update during the War Game.

Of course, this is just an estimate that didn't take into account Bell's final stats at level 3, disregard his magic stats & mostly keep it simple but as a default margin this is quite sufficient.

If Bell were a level 6 he wouldn't lose to any level 5 unless said level 5 had some super ability that would level him up; experience is only decisive when it comes to adventurers of the same level, but when there is a difference in level, status is decisive. Such was the case of Tione against Asterius, as basic as her fighting style was compared to an expert like Tione, he would have beaten her since her blows barely bothered Asterius.

In all the comparisons between Bell and other level 6s (Tiona, Tione, Hedin, Ryuu and Mia) Omori has said that Bell is inferior. It may be because Bell doesn't have the combat skills of these geniuses despite having the same level, but it is also possible that he is simply a level 5 compared to level 6s, hence his inferiority. My point is that there needs to be some explicit demonstration by Bell that proves he is indeed level 6 instead of just assuming it.

But either way, it's a waste of time trying to figure out through numerical calculations how powerful Bell should be; the boost due to his stats is determined more by Omori's circumstantial will than any numerical calculations, which is why in some battles he has shown a gigantic boost and in others a tiny one.

The issue is that so far Bell hasn't fight any level 5 & the level 6 he got weren't exactly the average type (Tiona defeated her teacher & Tione maybe would have done the same while Ryuu has now so many boost she can spair with that anomaly of an elf called Hogni).

You're asking for something pretty unfair, it's not like we can pull out of nowhere a level 6 who has no skills or magic that could increase his fighting ability while being only average in terms of fighting technique to battle agaisnt Bell just to see if they're on equal footing, the best possible option so far would be fighting a Level Boosted Aki.

Yeah yeah Omori is playing favoritisme & isn't even subtil about it but that's not an excuse to just give up. It's not a question about what Adventuer Bell would surpasse (that answer has been given a long time ago) but more what kind of antagonist or monsters he will face in the Dungeon could be expected as challenge (In MS 12 we got a Moss Huge who ended up reaching Level 5 power).

Bell's update before continuing his battle with Ottal put his agility in the level 6 range and of course he received his post-wargame update which could be a few hundred points more than what we are aware of. Bell's agility stat is important because it is what his fighting style revolves around, and the other stats compliment it.

As for Bells experience in combat, I think that was one of the primary focusing points of volume 17, which was to train Bell how to fight properly, sure Aiz had been teaching him before that but the Freya Familia has far greater experience then she does, plus Bell's teacher is a former king (Hedin Selland) and there was even an instance of him teaching his familia members how to fight better, so I really don't see the point of calling his experience into question anymore.

@AlfiaTheNoise

For each level, the adventurer goes up 500 points. I calculated it based on Hyakinthos fight.

lv1 to lv2 +500

lv2 to lv3 +500

lv3 to lv4 +500

lv4 to lv5 +500

total increase 2000

@Leinad91

The calculations are used to analyze how strong Bell is and how strong a level 5, 6, 7 adventurer should be.

Of course, experience can change the way and mentality when fighting. There is no way to calculate this.

When Bell had trauma of killing monsters, he was beaten by monsters on the upper floor. I would say that his experience decreased by -2000. If not, he would have at least dodged them.

I understand about the oomori's favoritism, imagine a level 1 beating a level 3 (with trauma). But for each situation there must be an explanation. If it is a normal fight, the calculations show who has the advantage.

@Pluton9

Towards the end of the fight Argana was described as being pushed closer and closer to the brink of death and she wasn't even managing to fight back, so Tione would have definitely won if it wasn't for Finn.

Ryuu was already said to have strength and speed comparable to Hogni's even before casting Agaris Alvesynth.

It is true no Loki or Freya executive is a "normal" Level 6, but you don't even have to go that far. Reminder that in DM18 it is stated Bell lost a couple of times agaisnt Van. Sure, he is far more skilled than Bell, but having Level 7 tier physical prowess was enough for Asterius to be overwhelmingly better than Bete, Tiona and Tione individually.

Asterius has no semblance of technique while all three of them are highly skilled, yet he even came close to matching their joint assault. So really, there is no excuse for even a single loss. A Level 4 Bell was still Level 4 tier even with A rank stats. As simple as that. So unless we get any indication Oomori decided to change that, Bell right now isn't better than an ordinary Level 5.

@Citrus Tachibana

In Collection of Scattered Fragments, a SS from DM18, when comparing Bell to the rest of his allies it is stated his technique and experience are far from comparable to Ryuu's. Reminder that compared to Ais Ryuu is only a match in terms of technique but loses in regards to experience, making her overall less skilled than Ais.

Meanwhile, Ais herself is the worst among her familia's executives when it comes to skill in fighting people. And Freya Familia are specialist in fighting people. So there are reasons to call into question Bell's skills. He is nowhere near from even coming close to be comparable to any Loki or Freya executive.

@Rigel31415

Hmm, that's odd, considering how much they crammed into Bell's head with all that time at folkvangr. However, he is in no way a novice and inexperienced combatant anymore and further training with Hedin and Lyu should mend this shortcoming.

While he isn't comparable at the moment in terms of technique and experience when it comes to the FF and LF, he'll get there.

@Rigel31415

The reason I called Tione a maybe was because she fall from exhaustion right after Finn give his little speech while Argana has still the endurance to survive a punch From Finn using Hell Finegas. So as far I am concerned the winner is uncertain.

Also I was purely talking of Bell in term of raw ability not combat ability that Bell will lose because of technique & experience gap, the same raw ability that the narration confirmed being superior to Ryuu in MS 15. As for the argument Van, remember he is from Freya Familia, that fact alone crown him by the narrative as having combat power superior to the other level 4 of other factions. Beside Bell classified Asterius technic & tactics as superior to him while Loki Familia who specialized in teams work noted. it would have been an easy win if it was for Tione rampage preventing them 3 to coordinates.

Tione was indeed exhausted but Tiona also had to push herself to her absolute limits in order to pull off her win, so I do not see how that puts her victory into question. Argana was also explicity stated to be in her limit, so what evidence do you have that Tione didn't still have as much fight to give in her as Argana. The fact that in the previous scene the balance had inclined towards Tione I'd say is quite telling.

There is a reason the term retcon exists. I was an avid defender of Bell punching above his level, but considering how things have been recently I think it is pretty clear Oomori changed that. Considering he didn't like how fast Bell was growing, Oomori setting him back makes sense.

Bell didn't recognize Asterius' skill as better than his in any way, only as superior to Asterius' own from his past life:

Again and again, the Labrys threatened his life, but still Bell made his way around to his opponent’s right side and aimed his knife above the spot where his missing right arm had been. But the minotaur saw through his plan. His skill and tactics were far sharper than what Bell remembered from their past encounter. A feeling similar to impatience gnawed at him.

It was explicity said a couple of times that Asterius' skill is nothing special at all. Bell, for as laughably inferior as he is to first class adventurers, was stated in DM8 to be comparable in terms of skill to a "veteran Level 3". So he is more skilled than Asterius. Meanwhile, by the narrative (as you say), Bete, Tiona, and Tione are way more skilled than Van, as they are first class adventurers and executives of the second strongest faction.

So if anything the gap between Asterius and the Loki young executives was worse than the one between Bell and Van. Yet a one level gap was all it took for Asterius to be utterly stronger. And yes, I know if Tione coordinated with Bete and Tiona they would have won, but that's not the point.

The point is that a one level gap sufficed for Asterius to be absolutely better than any of them individually; so much so he could face the three of them at the same time. Whether they coordinate or not fighting three people at the same time is obviously harder than fighting either of them alone. So that further illustrates how massive the gap between Asterius and any of them was.
