If you select property edit tool, life, and 65000, the deuterium will be more powerful. I would recommend putting everything into a much smaller space.
how is it FP with 6 views?
What you have here is a neutron-deuterium bomb, and if you'd like to make it more powerful, I would suggest using much more deuterium, and much fewer neutrons, as well as a titanium casing. Also, if you cool your deuterium, it will be denser, and you can therefore fit more of it into a smaller space.
