how about.. an Clone which is requires energy to clone stuff (well ofc you first need to apply the desired element to the clone and then removing a bit of the elements to be able to run an wire to it) and it's breakable,
why i want this you might say? well basicly i want to be apple to 'contain' the reactions that is an nuclear reactor but i also want the reactor to be able to basicly blow up if anything wrong happens (aka power to the clone shuts off and an 'shield' element (but not the accual shield element that is in the game right now) that's on the clone and the reactions in the reactor chamber is able to "Burst" out
