I asked DMUA and he said that end can be used if there’s sufficient evidence for characters being in close proximity to the Grand Mountains whenever a mountain nuking statement is made.
Arthur noted that a fight between Mica and Olfred would level a mountain.
At the time this statement was made, they were all in close proximity to the Grand Mountains. Which makes the statement perfectly acceptable for the mid-end calc.
163
Since there were two characters the statement was made in reference to, the calc would be divided into two as a safe assumption. Hence, the primary scaling value would be 975 Gigatons.
Bairon, Alea, Aya, Olfred, and Mica
They would all scale to the primary value (975 Gigatons) as the statement was attributed to Olfred and Mica. The Lances (except Varay) were all portrayed as being roughly relative to each other
Varay
Varay is repeatedly and consistently regarded as the most powerful Lance, I’m proposing that she should actually scale to the full value of the feat (1.95 Teratons). She could subdue the attacks of Bairon and Olfred at once with ease
Arthur
Before addressing his scaling in all this, I want to address something else
Multi-Element Combo
Arthur can combine multiple elemental attacks into a single, more powerful attack. He usually shuffles between 3 and 4 elements. He does this combo by either condensing it into a single beam
Or by focusing it into a sword for melee combat
With this in mind, I’m proposing that Multi-Elemental Combo be given a 4x multiplier off his base attacks
Since that’s out of the way, let’s move to actually scaling him
Third Key
Contrary to popular opinion (seen a lot of it on Reddit), Silver Core Arthur isn’t really at the level of the Lances. It’s mentioned by Arthur himself
That being said, he’s not that far behind them when utilizing Realmheart Physique. Bairon displayed some degree of uncertainty when asked if he could defeat Realmheart Physique Arthur
Although useless for scaling since Varay was holding back, she mentioned that there was a chance he could have been holding back
In support, Arthur’s raw mana output was measured to be in the ninety-ninth percentile which should place him at a level comparable to other Lances
Since he’s inferior but still comparable to the Lances, I’m proposing that he downscales to 550 Gigatons (Baseline High 6-C+) with Realmheart Physique, up to 2.2 Teratons with Multi-Element Combo
