Dysfunctional Rules X: I Cast Comprehend Rules

[ShurikVch]

Faceless Hate: When a victim of this disease takes enough Strength or Constitution damage to reduce the ability score to 0, the infection disappears. The characte's ability scores are immediately restored to what they were before the onset of the disease, but he becomes a monster with no face. The character loses his ability to see (and scent, if he has that ability), but gains blindsight with a range of 60 feet. He loses the ability to speak, but gains the Silent Spell feat if a spellcaster. The victim's alignment changes to neutral evil, and he becomes intent on killing all those who were his friends and family. When the victim has hunted down everyone dear to him, he turns his ire against all other living things. These changes are permanent, and remove disease has no effect. A wish or miracle spell restores the character, but nothing else will. If the victim dies and a remove disease spell is then cast on the corpse, a resurrection or true resurrection spell restores the character to life and to his original form. Raise dead won't work.

Firstly, I mused about how Cancer Mage - with their Disease Host class feature -

a cancer mage suffers no ill effects of diseases, except for purely cosmetic ones such as boils, pockmarks, watery eyes, blackened skin, hair loss, foul smell, and so on

- would "suffers no ill effects" from the loss of their face, and thus - would be able to see without eyes, smell without a nose, drink potions without a mouth...
But then it dawned to me:
-No mouth!
-No nose!!!
How the heck they are supposed to eat, drink, or breath?!!
Thus, unless they either have Iridescent Spindle, or specific anatomy (gills or blowhole) - they should be dead in a couple of hours top (excluding possible excessive Con optimization, persisted Deep Breath or Veil of Undeath)
Those who have some of aforementioned, would still perish in a few days unless they have access to ring of sustenance, psionic sustenance, Elans' Repletion, or Elemental type
