Hello, im the creator of Craftologia, a tech-focused pack, i added recently a recipe for the TechReborn Nuke, which kind of resembles a Thermonuclear Fission-Fusion Bomb. After exploding one Nuke in the Overworld, the sufrace hole was 35 blocks-depth and 74-width.

It is possible you add a config option to set the explosion radius?

Here i leave a pic to the recipe if you are curious about it.

Thanks.
