Well yeah, that's a pretty fair question. If you do not want to invest heavily into darkness resist, you can just raise your life regen accordingly for example, with 50% dark resist you need 50 life regen, with 0% dark resist you need 100 life regen, with -100% dark res you need 200 life regen and so on.

With 1 HP and capped dark resistance, we lose just 25 hp/sec at 5000 stacks (which is the cap right now) this means that we just need to have at least 25 life regen and we are done forever. I'm pretty sure that at the beginning of the league the degeneration was not working properly, so a massive amount of life regen was needed to survive the darkness, but right now things seems to work as they should. Well first of all we want to have 75% darkness resistance (not mandatory, but it helps). How are we actually mitigating the darkness? First of all you grab Chaos Innoculation and then you pay attention to not have any ES on your gear. This build manages to have just 1HP and no ES (therefore your EHP is 1), while stacking enough flat life regen to beat the darkness degeneration. but as you can see in the link above, the debuff stacks very fast and therefore it's pretty much impossible to counter it with generic % life/ES regen. As long as the amount of life/ES regen you have is higher than the degen you are suffering, you will not lose any life/ES (sometimes there are "visual bugs" or some strange stuff going on, like when using blood rage or RF). The main idea is that the Darkness debuff deals a percentage of your EHP (Life + Energy Shield) as damage over time, it does stacks over time and generally speaking is not sustainable for more than few seconds. If you are not bothered with cappung your dark resist, you can then invest a bit more into life regen.

This essentially means you do NOT need all the life regen I was suggesting down below, you can just gather at least 25 life regen somewhere on your gear and you are done forever. Which means that even at 5000 stacks we only degen 25hp/sec (with capped darkness resistance), having just 1HP. I do not know what happened in the last few days (since I first tested the build), but right now things are actually working as they should. I also strongly hope GGG will not destroy this "concept" in the near future, since it's a pretty cool use of game mechanics (and the main reason people love this game is to explore its depth in terms of mechanics, finding out cool interactions) and by itself doesn't really break the game. If you actually wanna progress into the delve, you need another character if you want also a fast MF mapping character, you can check out my MagicBlaster 2.0 guide. You do NOT kill stuff, you do NOT follow any cart, you do NOT farm maps, you do NOT tank anything. Let me make this clear, very clear, from the beginning: the only purpose of this build is to run in the darkness and grab all the loot you can find. His ideas allowed me to push the limits I previously reached even further.

This is something a bit different, which is not 100% an idea of mine I was theorycrafting a bit by myself and then sir Ghudda published his new video developing a similar concept. Hey guys, it's been a while since the last time I wrote a guide.
