I really wanted amarms to be a palindrome. But it's not. So I made it one!

I like amarms. It seems easier for me to get my head around than cycles, maybe because (in my solution at least) there are less arms to coordinate and have in my head all at once. I did notice as a newer player that doing a couple more campaign chapters was really helpful for seeing patterns faster, so I didn't spend a million years on this one.

Once I got past trying to drop double-bonded fire+water on the single-bond fire+water output, things got easier and I just stepped through the rest of the solve, with a minor detour into "oh no, I can't reach the calcifier, oh well, I'll just add another arm." It's probably obvious that I didn't even try to optimize secondaries or primaries. Pistons galore!
