Hero days to unlock	3

Doesn't actually allow you to delete register entries, instead it obscures them leaving clear evidence of the tampering. Can be used 2 times in a single game, or 4 once Treachery Treachery is unlocked.

You have discretely tampered with an entry in the register... You can do this 1 more time.
