You can shrug off magic of your sphere exceptionally well, even where others fail.
Prerequisites: Sphere defense class feature, nexus level 15th.
Benefit: You still are unaffected on a successful saving throw against an effect with a descriptor of your sphere, henceforth you only treat the saving throw as if you made it, even if you failed it. You do not gain the benefit of this feat when you are unconscious or sleeping.
Normal: You take the full effect against an effect if you fail the saving throw.
