We’ve seen that protodermis-based biomechanical beings can interact safely with normal matter (real water, rock, etc.), and even control it with their elemental powers. Is the reverse true? For example, would it be safe for a Glatorian or Agori to drink liquid protodermis, and would they get the same sustenance from it as they would from normal water? And can the Glatorian who have elemental powers control their protodermis equivalents?
No, and yes, with training.
