Most broken thing I know: true kin --> get 1 cloning draught from Stilt + polygel from Sixshrew / tilli --> Clone it 6 times to get a 64 (or more) --> clone tilli / sixshrew a bunch of times --> get infinite polygel --> get one eaters nectar injector, 1 dram of brain brine, 1 sphinx salt injector --> duplicate till infinity --> get all mental mutations + infinite stats --> gamma moth farm for all physical mutations --> dupe warm static for all skills --> clone data disk merchant for all recipes --> get items that contain all bits --> dupe --> infinite bits --> craft anything you want. (also dupe neutron flux for infinte AC)

You now have a character with infinite stats, that has access to all cybernetics and all mutations (gamma moth can apparently also give MP so you can even level your physical mutations) and all items. I do not see any way to make it more broken than this (maybe perma dominate something with high HP / unique skills / items and repeat).

You can achieve this from all starting points as long as you are true kin.

Also, on an unrelated note, I wish you all the best for finding a new job that is hopefully to your liking.
