BE WARNED: THIS TNT IS INSTANT (more "real" / use other timed explosives or det powder)
This mod uses a real life term called RE factor, which just so happens to be how big an explosion is relative to TNT, which minecraft already has.
This mod contains 5 tiered TNTs 4 special TNTs and a vacuum cleaner to clean up the mess
Basically the explosion gets bigger as the tier goes up. crafted with 4 TNT and 5 of that level of item (end being Endstone bricks)
Low tier explosive made with 3 gunpowder and 6 iron. useful for blowing up TNT from a safe distance
Just in case the blast wasn't enough, you'll also be volunteered for the minecraft space program as an added bonus
Let's face it, its what the average minecrafter would call a "nuke" but I wanted to feel special, ok? (it gives you wither)
I would honestly just craft it. you'll understand why it's British
EXPLOSIVE IRON BARREL:
Be the Michael Bay you've always wanted. shoot the barrel it explodes.
Item entities lag, so what else could you need?
