Eh, it's basically a fluff point, but the highest Blood Originium-Crystal Density is 0.51 and that's requires intensive monitoring/treatment phase.

[quote]The Blood Originium-Crystal Density reports, from the looks of them in general, indicate that 0.2u/L is considered early stage, wheras 0.3u/L is considered approaching mid-stage. Assuming 0.35-0.4 is considered being within mid-stage, 0.5u/L+ must be end stage already. Since it seems like high Originium-Crystal blood density makes you both deaf and blind, unless you have some other way to sense others, you're pretty much disabled by then.

However, it seems like blood density can be independent of the crystalisation process (Cell-Originium Assimilation). Eyja has really high blood density, yet her crystalisation process is only 8%. Compare this with Amiya, who has a crystalisation process of 19% with a corresponding Originium Crystal growth from her chest, but with a blood density of 0.27u/L, which is still 'mid-stage'. One would think that higher blood density would lead to more crystalisation, but which is it really? [/quote]
