How strong is the Warrior of Light?

[SentioftheHoukai]

Actually very little of that matters. Hundreds or thousands of other adventurers also have the Blessing of Light. Including the Warriors of Light from the First. Most characters with the Echo are not particularly powerful by comparison.

The player character is, even before starting the game, 7 times rejoined. Your character is over halfway to being fully unsundered. This isn't true of all denizens of the Source. By the end of Shadowbringers, you are 8 times rejoined. Somewhere in the Thirteenth there may lurk a 9th.

Then add to that, the Blessing of Light, the collected crystals of light, soul stones. By modern mortal standards, the WoL is deific.

I never quite understood the justification for WHY we seem to be the only soul on the Planet that is Rejoined like that. Aside from "plot convenience", was that ever explained?

The Ascians seemed to think it mattered.

We kicked their asses pretty soundly. If anything it seems like there's a negative correlation, the more fragmented-down souls seem to have an edge in at least the initial fights. (Or, more likely, it doesn't actually correlate to any meaningful level.)

I'm not even remotely convinced of this, to be perfectly honest. Seems to me the only thing "beyond" the Ancients is Dynamis, and even that is arguably a stretch. Take Dynamis out of the equation, and Unsundered Souls and Creation Magicks trump those without in nearly every instance. The narrative outlined it as near godlike power for a reason, so as far as pure power levels are concerned it's clear the Unsundered are the superior combatants and win that fight. We won against the Ascians Three because the power of plot demanded we do so. Even Emet-Selch says so, he could have just killed us as we remained blissfully unaware of his presence.
