As in Week 1, the MVP of my solve is a hex arm that pivots.
(to be fair, the vitae hex arm also dropped ~30 sum when I found it.  But it is just doing basic hexarm stuff)

Also as in Week 1, I fixated on this MVP the minute I found it.

It remains to be seen if my fixation is warranted.

Fun fact: the Fire atoms are the only ones that never get grabbed.  Hence the solve title.
