Fever Fetish questions

[AdmiralZhao]

A ring of regeneration will keep a diseased commander alive indefinitely. They won't gain hitpoints, but they won't lose them either. In my current game I have several sages and the like who caught diseases, and I fitted them with rings of regeneration and fever fetishes. They're all all fine a year later.

As I understand it, a fever fetish will produce one gem per turn as long as its owner is A) living and B) not at full hitpoints. If the owner doesn't meet those conditions, then the gem production is more sporadic.

Shroud of Battle Saint with N4+ blessing works also.
