Well, I was researching for my new Original Fiction smut story (I will return to DDR soon, honest! ) and, well, my Succubi are different, and the main character is so awesome she can take a dip in concentrated Sulphuric acid.
Then I had problems comparing that to human norm since search engines hate me.
What I found so far in regards to human tolerance of pH says our resistance is stupidly high. Our skin is so acidic that most bacteria die horribly on contact with us while we don't even notice acid concentrations 100 times higher than that:
roughly, consumption is possible 2..11. Swimming is considered safe 5..9
https://en.wikipedia.org/wiki/PH
the "buffering in human tears" paper
http://iovs.arvojournals.org/pdfaccess. ... 48/747.pdf
shows that chemicals in out tears auto-neutrazize water in range of about 3..11 to eye default of 7.5. Our blood contains even more of that good shit, so we probably won't even feel that something is wrong with water in this range for at least half an hour...
This hotspring review states 1.4 is nice and cozy: https://www.tripadvisor.com/ShowUserRev ... ohoku.html
(hot spring 1.1 diluted to 50%)
This article says people swim regularly in 3.9 (possibly 2.5 in prior years)

This article shows children splashing merrily in 11.3:

So, I assume that mortal's default range is 2..12 (with "it itches" at the extremes)
And here you were wondering how One Piece characters could swim in that whale's stomach juices
That makes my Succubi with their basic range of 0.7..13.3, while extraordinary, not broken at all. That resistance is only 15x baseline human's. Also fits the ability of the main character (whose END=22 is so stupidly high her resistances are 5.3x the racial norm) to take a dip in concentrated Sulphuric acid.
Also, consistent with heat resistance I set for them, where the range 37..110C affects them like it was 37..42C. That, also, gives 16x heat resistance.
In fact, I think I will express resistances in terms of multipliers from now on.
... Ugh. Nerfing now. Acid 15x, heat 10x and still my main character could scoop magma with her bare hands (it's "yeowch, like a hot potato!") to lob at her enemies. While standing next to said magma barefoot. 1256C -> effectively 60C
... Ugh 2. She can walk through a blazing inferno like it was a very hot sauna.
I should be very, very careful around so much fanservice potential as it can easily ruin my story. I hate PVP.
