Hey guys !
Sorry I haven't posted anything yet ,I didn't get much time to work on these rules .
I'll post new rules as soon as I can.
I like this rule and I've just taken it for my games; if your characther has below 30 corruptions points and do not act with knowledge in a corrupted way (I.E possessing or using daemon or xenos weapons, consorting with heretics, infiltrating know cultists, etc.), they can throw a D10 after using a fate point; if they get a 10, the fate point isn't spent.
And once per session, if they burn a fate point, on a 10 it is just spent.
It is a good stat, and it encourages the players to purifiy themselves, act accordingly to their faith and etc. by spending XP to buy back corruption points and act in a puritan way.
