Well thought out and described.

But I'm glad that it is not necessary to make such builds to win all fights, you can do just with "normal playing" (items you find on the way, no barrels, no scrolls, things like this). Because such builds were mostly impossible for me (e.g., I don't like to meta for items, my barb does never wear shoes, I never use potions other than healing stuff, Auntie Ethel deserves to be killed, I would never kill an NPC like Kagha just for an item, some items are too ugly to be used etc.).
What I take especially from this build is that the influence of gadgets on gameplay has to be toned down considerably. One potion as kind of core feature for a build is a bad thing.
