Ok, but getting away from an example of exaggeration, even a +7-8 to all saves for starting with a strong Cha score, getting the +6 from your race and spending a pittance on a moderate cost +cha item is pretty damned amazing. That's a 35-45% lower chance of being affected by a given spell effect, on top of the SR you're packing (and good saves in the two most important attributes).

And you can get away with it because your class packs full BAB and +Str and more attacks in a full attack than an equivalent level fighter-type to keep your melee more than up to date and +Con to keep you durable (while also offering nat armor).

So like I said, it just feels a bit much.
