Well just wait for all the speed of sound stuff from V13 and V14. Velgrynd is faster character so far and she's not even FTL or SOL. Hinata couldn't see it traveling plus they all new he was targeting Chloe and started moving before he fired. At least Hinata who was also closer. Regardless I'll touch it momentarily.
Yeah, some of these create inconsistencies IMO, we have to decide which is an outlier and which isn't. It seems that downgrades is inevitable for mid-tiers though.
We didn't really see Hinata's perspective on Granbell's Melt Slash, and considering her speed feats, it's safe to say that she can perceive it. Furthermore, Granbell actually hit her (possibly with a Melt Slash) so hard that even when Hinata blocked it, she was still launched a considerable distance away from Granbell. So Hinata must've dashed
really fast to intercept Melt Slash.
My point in bringing this up is that while logically this is just a Relativistic speed feat, it can be very easily interpreted as an FTL feat if we assume enough bloated numbers and instances.
I have considered the possibility of Granbell and Hinata getting downgraded to lower than Relativistic speeds, leaving only Disintegration spells as Rel+ attack speed. But this is very contradictory with other instances such as Hinata having incredible speeds in Rimuru's perspective buffed a million times, and even reaching the speed where Rimuru could no longer follow her attacks with his perception (although Hinata was pushing herself to the limit).
There are simply a great deal of inconsistencies with Fuse's writing (like Yuuki being 100 m/s fast at attacking, making him slower than even ******* Gobta).
Not its definitely going to depend on how high into MFTL but with Thought Acceleration they have FTL perception/reactions (not movement) and Rimuru has like MFTL+ (315 million times). What's important about this is that the activation of magic and skills scale to this speed. Even if they can't move that fast it'll mirror how Rimuru kept with Velgrynd via continuous Spatial Movement.
This isn't relevant right now in terms of causing any updates, but I would love to see calcs and CRTs or even just a blog post about these in the future.
Rimuru with Ciel is definitely at least FTL in perception and reactions, but I'm not certain with the others.
Veldora was only hit by Melt Slash but it wasn't potent enough to do much. Demons are weak to Holy magic but even disregarding that. Diablo already demonstrated that there's no reason to fear Disintegration. If have a resistance to Holy Attacks and Spiritual Attacks you'll be fine as long as it doesn't surpass your resistance.
My question is about whether or not Disintegration can be resisted through sheer durability, because so far it isn't really being portrayed like that (in my opinion, at least, correct me if I'm wrong).
The reason why characters like Veldora shrugged it off was because they specifically have resistances against it, not that they're too durable.
So it sounds more like hax potency than attack potency, though that's not to say that Disintegration can't be quantified as AP as well.
Rimuru just used Uriel's barrier which only resisted it because it applied his newly attained spiritual attack resistance. The reason why Disintegration was so dangerous was because of unpredictable spiritual particles that would go through barriers. But if you mastered the pattern then its possible to block it.
Well yeah, there are many other Holy-based or spiritual-based attacks in the series, just that Disintegration is the strongest of them all, often called as the
ultimate destructive magic. Basically because how most holy attacks don't do anything to humans/non-magic folks, but Disintegration kills everything it hits.
I think the unpredictability of spiritual particles and its space-time ignoring features definitely contribute to its haxiness.
Even Kai and Adalmann were hit by Disintegration and survived due to the potency.
I wouldn't it existence erasure but more a kin to deconstruction or atomization in the sense it attack fundamental aspects of your being. Which if powerful enough will destroy them but not erase.
Didn't Adalmann survive by chance? And some other factors I'm forgetting about.
As for Kai, he didn't get hit by Disintegration IIRC, Shuna specifically just targeted his armor. He would've been wiped from existence if Shuna wanted to, but she just wanted to humiliate him. She pretended that she misfired the spell but Rimuru comments in his mind that the fact that Shuna can control Disintegration to a degree that it only affected a person's clothes means her control over magic is top tier within the verse.
It still kinda sounds like Existence Erasure though, at least it qualifies per this site's standards (and at least I've seen characters with less potent/impressive abilities that counts as EE), despite also having functions of deconstruction (more like sub-atomization IMO).
