Basically the Gold Solution... MechA 7. MechA 6 is probably possible with Ag bonding shenanigans... I cannot easily see how lower is possible as you seem to need to handle single atoms of Hg produced, though you only need access to one side of the trauma glyph to grab them if you use bonded Ag sticks or crooks etc, but then at the end you'd need to do some messing about with unbonding extra stuff on your now Pb atoms out in the field with waving around... I'll leave that to the new (and old) hardcore fanatics.

Good luck Timmy!
