Let me start by saying this is NOT another thread saying to remove energy.
My idea is for something called "Mist Tank Software Upgraders." If I've read right, according to the story a Knight's armor slowly gathers "Mist Energy" from the air. Therefore, it has some sort of program on it to do so. I'm only saying that to explain the name.
These upgraders would add, say, +5 to maximum energy each. They would be made through crafting and be untradable. The cost to craft them could be, say 1000 crowns and 20 or so Energy.
The materials required to craft 1 upgrader would be of a moderate amount, and not ludicrous numbers of materials. What items combine to make them or how many is up to debate. They would also have a maximum that they could raise the capacity to. For some reason, I was thinking of 250-ish. Then again, I'm not with Three Rings so I wouldn't be the one deciding.
Any suggestions are welcome.
software? you know there are things that absorb other things without software right? the armor is not a piece of electronic anyway
aside from that in one form or another this as been suggested
