Ves immediately got sidetracked. Though finishing the luminar crystal rifle was important, he could not get rid of the notion of developing a new luminar crystal formula that could essentially substitute the role of P-stones.
Though the material composition of P-stones varied considerably, they all had one property in common.
They were capable of storing spiritual energy. Their capacity was quite big for their size. What was truly remarkable about them was that they were stable and reliable. Even if Ves filled them to the brim with spiritual energy, he was fully confident he could leave them out for years and come back later to regain everything he put in without missing any portion.
As far as he was aware, the energy stored in P-stones did not decay over time!
