After somewhat lowballing the lagoon as having the same lateral area as the walkable area, the other ranges for the calculation look like:
- The Mid End (including the Lagiacrus’s depth level up, or about half the lagoon) is 6.1 kilotons or just barely the minimum of 7-C Town level.
- The High End (including the entire lagoon, which is not logical, since you don’t take damage at the very edges of the lagoon while underwater, even if you don’t dodge, implying the energy doesn't reach that far) is 12.3 kilotons or 7-C Town level.
However, I think this is basically as high as it's gonna get if/when more concrete calculations come in, at least using the same methods. Even if I were to include the large outlying areas of the lagoon in the energy calculation, the attack definitely won’t break 50 kilotons (the halfway point of Town level). Food for thought, I suppose.
…this Lagiacrus showing it shrugs off an attack from its supposed rival even with a weakness to fire…
No but this Lagiacrus is literally built different. It literally no-sells attacks from a Rathalos and then has a long ass fight with the player character that it ends up surviving by the end of it. That ain't normal for an Apex Tier monster post-game.
My opinion on “cutscene power” is the same as it was before. Yes, this Lagiacrus tanks two fireballs here and is really going for that Dalthydon to the point it’ll behave highly aggressively to capture it. But there is nothing implying this monster is different from other Lagiacrus we encounter in the Scarlet Forest. The same individual takes as much fire damage as anyone else, and we all know
their Turf War. Even in the very same hunt (which I can upload footage of), Rathalos and Lagiacrus have the same turf war showing they can handily trade blows and it’s a toss-up depending if Lagiacrus is fully charged or not—this individual
still loses to Rathalos unless in its supercharged state.
The real kicker is that, if this individual were uniquely powerful among its kind, the characters would likely mention
something pertaining its unique nature. Erik and the Hunter, the two individuals on site,
have already concurred before on the exact issue of enriched monsters in the Wyvern Sparks and Rose Thorns cutscene. But all that’s said is:
"A Lagiacrus! That's the cause of all this!"
It’s a Lagiacrus! That’s the twist. The only odd thing here is its location, not any property of the monster in question. It's not Tempered (we know what those look like) or enriched by the Dragontorch (especially since it explicitly just recently arrived in the Forbidden Lands). It is, by all accounts, a typical Lagiacrus. It's even got 3 Strength by the in-game metric, while in-game individuals who still lose to Rathalos can go up to 5 Strength.
Is there any evidence that the hunt goes for a particularly abnormally long time? I don’t recall them mentioning something like that. In lieu of such things, that is my stance on the matter based on the evidence provided.
yet it gets absolutely bodied by Uth Duna. It slightly annoys Uth with the first bite and only makes it go back with electricity discharge
While I agree that Lagiacrus definitely doesn’t win the encounter, I wouldn’t say it gets
bodied by Uth Duna. In an extended physical brawl the Lord of the Seas definitely stands as inferior, but the lightning panic button inherently makes an outright at-parity loss against Uth Duna pretty hard to imagine.
As an aside, I do wish they gave Lagiacrus two Turf Wars against Uth Duna with the same charge-dependent mechanic, because now it feels like vs. Uth Duna, Lagiacrus can pull lightning out of nowhere while against Rathalos if it’s not charged, it can’t use it at all.
