Stickman with antimatter can go through...
Dont think its possible with a single bomb...
if anyone would like hints on how to destroy elements in the wall, comment the element and i will (reluctantly) tell you how to destroy it.
also, it is possible, although it took a while for me. i did not use a bomb, i destroyed each element in its own way, like using ligh for the heac, acid for the conv, etc.
A CONV-PSTN driller easily went through, since you used CONV, you can't ban that.
If you ban stuff like BOMB, you should not use CONV in your wall. :(
