Technically you don't need track or animismus, but you need the following: stab gold input bonder debonder deposition (I don't care what you say, Mr. Barth. That's what it's called.) output arm Then you have a choice of mors+vitae inputs, animismus+track, or animismus+second arm. Interestingly, this takes exactly 126 instructions to do each half of the monomer; the code is basically the same but it grabs the mors and vitae in the opposite order. I was surprised that it took the same amount of time to do each.
