Ever since I rolled a fat person - a woman elf who is "stacked with incredible amounts of muscle and lard", and a miraculous survival fighting a werelizard that ripped off both her legs by throwing a silver arrow into its head turned her both into a "corpulent" glowing aqua-eyed lizard and one of my best adventurers ever, with an amazing 400-ish non-scummy notable kills, I've been wondering whether descriptions are static or not and whether I could lose weight. Keeping her in hunger was tried but had no effect.
Having made it this far into the game with nothing but guts, stealth and careful morning star and axe strikes, I no longer felt like lame tricks and grinding are cheating. After all, legendary swordsmen sometimes retire into the wilderness to practice for years and return like demigods. Starting on a new goal - to either become worthy of uploading here as an immortal were-lizard husk cave explorer, or to become truly legendary, or die - I had Salore Flowerpetals the Pristine Kiss of Embracing (her actual RNG-given name) walk into the middle of a haunted plains. There, I located a beaver horde.
I systematically decapitated the beavers, then as their heads came alive, punched their teeth out. I then lay on the ground for two entire days in my lizard form, letting the toothless beaver heads gnaw at me. (amazingly, they did eventually break every bony body part and "dent" my tongue and muscles before I turned back into an elf)
This had the effect of taking my strength from low to superwerelizardly, like all my physical abilities. What it also quite interestingly did was raise my focus and intuition similarly - made me superwerelizardly, and superelvenly when I shapeshifted back, intuitive, and superwerelizardly in ability to focus where my lizard form had previously been rather unable to focus at all with very low. However, the thing worth noting the most was, I got the answer. Namely, it changed my werelizard form from corpulent to muscular.
I'm currently save scumming and seeing
* whether it raises my other mental abilities, 'cause I'm really not sure but was surprised to see how high social awareness a lizard can have
* how the description evolves during the beating. Assuming I can find those badgers again.
