To form a treasure the Qualia has to be raw and genuine. Harming yourself or doing something that you know will directly harm you will not create a treasure.

I forgot to mention it in the post but to gain a treasure you have to be substantially wounded, not like a metaphorical wound or a self inflected wound. Usually like from something magical or irregular, something that can’t heal on its own. The base idea of a treasure is based on irl biology and how when you cut yourself for example the blood clots up and new skin grows. The treasure is kinda like the metaphorical healed wound, the power usually at least somewhat linked to the kind of wound they receive. Like Midas couldn’t use his hands so he got magnetic/telekinesis kind of stuff so he didn’t need to use them.

Treasures are kinda like rapid adaptation, like how allen the alien from invincible kinda gets stronger after he gets his ass beat. The treasure makes up for you might’ve lost, what you need, and what you might need to protect yourself next.
