I'm glad to see some interest in EvilHack appearing here in RGRN. However, I don't check posts here very often. I'm more than happy to answer any questions about the variant though, I just need to be aware of them. Thanks to those that have fielded questions, I appreciate it.
Best place for answers is to visit #evilhack via libera.chat (IRC), #hardfought works also. I frequent r/nethack on Reddit as well fairly often. The wiki entry for EvilHack is pretty much up to date also -
https://nethackwiki.com/wiki/EvilHack - there may be some minor recent changes missing, but otherwise is solid.
