While I think it should be a flat amount to avoid certain absurd builds, -1 seems weak when a feat can give -2. A class ability should at least equal to a feat, in fact it should be feat+. I really don't know what the orb wizard should get, if it stacks with the feat it can quickly get nasty. Heck maybe they get the feat for free even if they don't have the Chr for it and its provides -3 instead of -2.
It's probably worth noting that a feat that gave -1 to all saves would be a great feat. Spell Focus is... almost a reward for having a high enough Charisma. Or possibly comes with an iron shackle forcing the wizard to have a high enough Charisma, depending how you think about it.
