So I was just watching a youtube video when Nigun vs Ainz or Ainz and sunlight scripture was in the suggestion. [Holy Smite] 7th tier was used. Calculating it is based on assumptions, for example:
The spell was cast, and a pillar of light broke through the sky.With a loud whoosh, a seemingly endless cascade of holy blue-white radiance flooded down from the heavens, submerging Ainz, who simply raised one arm to shade his eyes.
Makes me assume it's 2000+ meters high or something but i'll use 500 meters as the height, even the manga makes this beam seem so high it goes off panel. The width is 3-4 meters depending on how you look at the adaptation but i'll use 4 meters. Making the volume 25132741228.718 centimeters.
Now comes this part:
This sacred power would annihilate all evil beings, and even good entities would meet the same fate. The difference was only if they were reduced to sightless atoms, or if there would actually be remains left behind. This was the awesome power of magic that exceeded the realm of humanity.
There is some truth to most of this since 7th tier isn't present in humans and this makes me assume it's atomization? Assuming the value given in the calc page is j/cc then the total energy is 1,820,020,882,623,448 or 434.99543083734414495 kilotons and if you use vaporization of a human you end up with 29.356171046574498718 kilotons.
Another way of calculating this. If it's heating the air... I'll use air density 1.225. Making the mass 30,787,608,005.17955ÔǼ. To burn a human body to ash it takes 90 minutes and between 870-980 celsius, I don't really know the temperature to instantly turn you to ash or vaporize you so I'll use this. The Specific heat of airr is1005 J. So 30787608005.17955 ├ù 980 ├ù 1005 = 3.032271512430134e+16ÔǼ or 7.2473028499764193811 megatons. Or maybe time sustained has a place in this? Well anyways if you've noticed this does run into the same problem as the fairies calc as this assumes it's a level 1 human or whatever level you're still human of this calibre.
Well all of this is assuming anything I've done here is correct lol...
