User blog:Zanybrainy2000/Abyssalcraft: Oblivion Deathbomb yield

Introduction
So, I was messing around with a 1.12.2 Minecraft modpack known as Hexxit Updated, which included Abyssalcraft as one of the mods. I decided to mess around with some of the things, and I managed to find an item in the mod known as an "Oblivion Deathbomb". So I just ignited it in a cave dimension and got this as a result:



It absolutely obliterated every block in the range of it.

(It also spawned Sacthoth, the Harbinger of Doom on a plate of obsidian)

And that's what I'm going to calc, today.

Calculation itself
I used the tape measure from Bibliocraft to measure the length between one end of the circular radius to the other on two different blast zones of two different OBD's, and I got 161 blocks for one, and 163 blocks for the other. I will average out this to 162 blocks for the average diameter of a single OBD explosion.

First, I require the volume of the spherical explosion, which is calculated by doing V= 4/3π * r^3

The radius is half of the diameter, so:

162 / 2 = 81 meter radius.

I can now plug this value into the formula.

4/3 * π *  81  ^ 3 =  2190000 cubic meters, or 2.19e+12 cubic centimeters.

I've checked if any stone blocks were destroyed in the explosion directly after it, and there were no stone blocks lying on the ground as items, which means I can safely say that the blocks were actually vaporized. Vaporization is 25,700 j/cc.

2.19e+12 x 25,700 = 5.6283e16 joules, 13 Megatons, which is a fairly low-end City level

This isn't too insane of an outlier as compared to vanilla. The Abyssalcraft bosses are stronger than vanilla ones (Such as the boss that is summoned from the explosion). The wither is incapable of surviving the epicenter of the explosion, but the AC ones can actually facetank it with minor health loss (4.5 hearts of damage at most). The player is also capable of fighting the boss that is spawned in the epicenter of the explosion (Alongside the other AC bosses that are stronger than Sacthoth), so it should scale to an endgame player (Armor stronger than diamond, such as some of the Abyssalcraft armor)
