This seems like a REAL large project... I have an idea, but it might be stupid...
So, We get the earclips in the one place that i dont know what to call, but they dont give any stats.
So, what if...
Every chapter, we get another type of hypnosis item, except it DOES give a stat boost.
So, Lets say that in Chapter two, We get a bo-staff made of metal, but it induces hypnosis. Maybe,in chapter 3, Our MC learns of the effects of the earclips and possible bo-staff,(Only available on the non-slut path) and learns of a way to temporarily get rid of the effect.(For the chapter, or requires material from the enemies and lasts for X ammount of battles.) and, In chapter 4, MC gets armor with same effect, but supplies Much more defense then the clothes. This goes on until the final chapter.
Consider it if you want, Im just a fan of the game.
