I've played Cataclysm for a long while for sure, and I would like to post some of my findings after all this time. However, to start out, I will be posting a series of tests on Admittedly, I did just spend a decent amount of time typing this out only to be logged out and then lose the wall of text I created. But here it is again! First off, I'd like to thank the dev that integrated the search option for the debug mode (and devs in general, you guys are ballers!) cause these tests took a lot of items to confirm. Now let's begin...
All control tests were performed with a 8-8-8-8 no traits no skills survivor
I started with water, since it is a big source of detriments in all form except for clean. Your standard water (from a toilet, river, sewers, and maybe a few other places) is quenching, but causes food poisoning. I tested to see if all water was the same, and I found that sewer water, swamp water, river water, and tap water all act the same with only different aesthetics (Drinking 5 straight from the source and 5 from a container filled with water from the source). All were simply Food Poising. However, drinking sewage around Toxic Waste Dumps and Hazardous Waste Sarcophagi raised my radiation, unlike the other sources by the same name in Sewage Treatment Plants and Sewers. My test with normal water was to drink it 30x, then 30x with Disease and Poison Resistance, and another with Expanded Digestive System. Every time I got Food Poisoning, save for two times with the CBM. Moving on, I found that Acid Water did not raise my radiation, but cause minor damage to your torso and cause a bad feeling, but interestingly enough not Food Poisoning. Now I wasn't sure if I should consider sewage samples as water or food (Think about it). Regardless, I found that if you drink it you get almost all bad mutations, but with the trait Robust Genetics you can get a fair amount of benign mutations. This does not offset the vast amount of vomiting you will be doing though.
Next up, I messed around with buildings. My findings were little but, to a new player, potentially helpful. This test was me hanging around one of the areas for Two Hours. My first test was with the sewage around Toxic Waste Dumps and Hazardous Material Sarcophagi The control was the same as mentioned above, the test was with iodine pills. Ten control tests resulted in no perceivable pattern of mutations, and about 400-450 rads. With Iodine pills, they all had one random mutation, but capped out around 50 rads.
I've noticed that gobbling down every pill you get is no longer a viable strategy, to some extent. My tests showed that the amount of painkillers that could take down an elephant is a happy buzz for your average survivor (50+ pills and hours of waiting). However, enough alcohol and liquor to get drunk mixed with two oxycodone, tramadol, or codeine pills will kill you. I'm not quite sure about Adderall, aspirin, or illegal drugs.
This was my first time doing a test that I posted (I do a lot on my own time for Dwarf Fortress as well). Tell me if I'm biased, or if I should do more tests. This was for new players mostly, just as reference. Any feedback for me is good feedback, cause I'm new to this.
