These days, the venom brand has a low chance of poisoning monsters that resist poison, though I assume it only applies to demons, natural monsters, and plants (can't exactly test it in Wizard mode since nonliving and undead monsters are generally outright immune). Anybody have exact numbers for the mechanics, or any idea when that changed? --spudwalt (talk) 04:24, 17 July 2020 (CEST)
- Oh, found it! It was tucked away in mon-util.cc. If poison resistance is 3 (immunity, this includes undead and non-living), always resist, otherwise 2/3 chance to resist (excluding effects that ignore resistance, currently only poison arrow). This was changed in 0.18.
