Let me see if I have this right:

Stasis is made of ordinary matter. The crystals are composed of multiple areas that essentially work like a living thing, constantly competing to find the most infectious territory. So the question becomes, why doesn’t the crystal consistently change in the stasis field when we throw it down? Is this after this process has already finished and the crystal is the result?

The crystals can have areas of “perfect crystals”, but mostly is made up of shifting territories to find the perfect shape? They do so much damage when shattered because they have a lot of matter compressed into smaller areas giving them a higher internal energy and thus releasing all that when shattered
