I get the feeling that "plz" would be enough of a description. Then again, I could be wrong.

Can you add an explosive device, preferably an expensive but easily detonated one, that creates a smaller version of the Draconic Reactor's explosion? Say, about half the size? Would be convenient when... redecorating... the bases of other players on PvP servers. Building and starting a full-scale reactor is such a bother. Besides, one can never have too many explosions.

lol... Redecorating...

I have considered it but any explosive device along the lines of the reactor would have to follow the same lore in order to make sense and therefor would itself have to be some sort of reactor similar to the normal reactor. I think it makes more sense to just use the reactor. Its not like you would have the resources to set one off every 5 minutes anyway unless you are playing creative and they already have variable yield.
They are also very easy to detonate. You just have to look at it the wrong way and your enemies base is gone!

Or, it could be a reactor, but crafted into a single block. That means instead of awakened draconian, It uses just dragon hearts. It also does a smaller explosion, but less energy. Great for lower end computers and... redecorating.. only a single spot and not an entire planet!

P.S. I guess I should never look at my bases reactor wrong, eh?

There isn’t really a reason to set off ANY explosive, even TNT, in survival. Explosions aren’t particularly helpful.

I think what they are asking for is basically a compact Draconic Reactor that can do nothing but explode. Make it as expensive as a Draconic Reactor, and they’ll still use it. The lore bit is pretty simple: you skipped all the shield and safety bits.

It is for Massive terraforming or you want to "help" your friends severely remodel their base. AKA Destroy it. It's hard without massive bombs. (A.K.A. Not survival)

Actual terraforming is better accomplished with a Draconic Staff of Power, nevertheless other mods.

But redecorating houses takes so long if you use the Staff. Pocket reactors are probably going to be much faster.

Might come in DE3 no plans in adding it right now.
