I am writing an instruction for using some software at my work, and have a somewhat tongue-in-cheek section that covers techniques that should only be used in the most dire of circumstances when there is absolutely no other way to produce a result.
I have an "Expert-Level Techniques" section already, and am trying to find a good word to replace "expert" in this tongue-in-cheek section that does justice to the type of techniques being described. These are techniques that would be frowned upon by other experts in the field, but can deliver results in the most dire of times.
Originally I considered "God-Mode" (referring to the similar usage in many video games for when you cheat) and I've had "Black-magic", "witchcraft" and "Voodoo" suggested to me, but I want to avoid using a word that might be seen to reference race or religion.
Single or compound words, or phrases would be fine in this circumstance.
