I don’t think I naturally write people who have your 8 or higher. I have a high threshold, and you write what you know, so this idea of being in so much agony was hard for me to grasp until I lost my first tooth to pregnancy decay.
Nothing specific is coming to mind form older stories so nothing is memorable pain-wise. Currently, the two dealing with pain is Wolf & X Bunny and X Bunny is living under a curse to have “traits of rabbits” --and a rabbit can kick hard enough to break their back. So these beings can accidentally paralyze themselves over a fool move, and magically be back up the next day if they aren’t ended right then and there. The beginning scene is X Bunny being tormented by someone who is interrogating them by pulling out their fingernails (which just grew back within minutes), and the dumb bunny is just scoffing that they didn’t break it’s back which would have lasted longer.
I never did write the pain threshold for that, but the attitude is certainly a 1.
Then there’s The Essence of U. Daniel avoids fighting all the time, but he occasionally does with the friend he hates, and he treats the pain like it’s an everyday part of his suffering this guy’s life.
Off-Topic: I really need to stop typing but can’t seem to because I have a SHIT TON of things on my mind and the distraction is a grade A killer, which is sad because I actually want to say things that are pointless or not.
There’s this thing called “being dramatic when she thinks she needs to be” and Bethany could act as if the pain doesn’t bother her or she can go up a thousand and say she sees the lights and will probably faint/die/become a corpse if this pain does not stop.
