I've added to my house rules Chaos-God specific corruption rules. The idea is to use those nice tokens to track each gods corruption separately. Also, I wanted to distribute more corruption in general and have corruption be less permanent to have more epic moments involving game play and player choices. Insanities and mutations can also be treated temporary making them in volume less ruining for a well developed character. Instead, they act as an incentive to get cleansed.
