DESTROY THE INDESTRUCTIBLE USING TETRAHEDRAL PLANES

Despite hitting Iasonias' back twice with my strongest sonic exploding punch, it failed to destroy the diamond on his body. He was indeed indestructible to most harm.

"Is his conjured diamond real?" I asked Asterix on my earphone.

"It is not diamond but what he conjured is similar to diamonds but much tougher than diamond", Asterix replied to me.

"Damnit, I can't break the diamond back?" I asked her.

"The diamond back is not real diamond, but it shares the same atomic structure as diamonds", Asterix told me suddenly.

"The diamond body is made from Neutronium atoms joined together in a lattice-type structure which makes it extremely strong just like diamonds", Asterix said to me.
