[6.0 spoiler] Limit breaks

(2.a. OK yeah in Elpis we're a bit "thin" as they describe us, but it's never suggested we're this way when time travel isn't severely weakening us)

but it is. repeatedly even.
1) the reason the ascians were nigh unkillable and uncapturable until we devised many extreme and convoluted methods to counter that? because their aetheric density is much much higher than ours
2) the reason emet-selch saw us as pitiful half beings unworthy of life? because we are mere fractions of what we could be
3) the reason the song of oblivion is able to transform modern people directly while in ancient times it could only corrupt creation magic? because we are much less aetherically dense than the ancients.

dynamis is weakened by aether yes but its not as if a single drop of aether overpowers any amount of dynamis, or the entire world ending event were trying to stop wouldnt have worked to begin with.

Relative to ascians? Yes.

But when dynamis is first introduced as akasha, it's still framed in the same way: There's not much in the way to directly interact with it nor make use of it. Ascians might be a 40,000 lumen flare to our 1300 lumen floodlight, but we're still beings constituted of aether on a very aether heavy world.
