Put atleast a pixel thick wall of insl
Try making a shell, filling it with DEUT, and then setting the life of the DEUT to a high number like 5000. Then, add protons. This should blow up the RBDM, but to resist this, you can block PROT with INSL. Try adding some deeper into the wall.
basic proton gun can easily destroy everything, also way too thick wall -1
