I've never really bothered including what the mibs were assimilating all the time since there is only stones around us. I did mention they were focused on the ground as I had plan on flattening the terrain, since He couldn't see though the mist I kept it to the wayside for later. I mean either way you look at it you have to go through the slime first before you reach the rocks as there it literally nothing else to assimilate to build things out off. In either case they wouldn't have a problem eating through ice.   

  Also I never messed with electromagnetic energy in the armor as far as I can tell. He sheds his momentum from high flash-point into his blades, which is why he can move from one sword to another and stop instantly. It doesn't effect kinetic energy aside from himself. It's that or he has complete control of his momentum, which is even worse as that would make him way to powerful.
