After the new Knowledge Chain unlocked, Bai Fu's gains from her Knowledge Chain became——
[All Spiritual Ability System active skill effects +80%, Spiritual Ability Resistance +60%, Spiritual Ability Recovery Speed +4/minute, Inspiration +5, Spiritual Ability System bonuses unlocked]
The boost to Spiritual Ability System active skill effects was not very noticeable for her at this stage, because most of her skills were passive or those damage-free control-type, assistive-type skills, and some skills were so unique that they didn't benefit from the bonuses, such as Combat Etiquette.
But the lack of usefulness now doesn't mean it won't be useful later; once she masters more skills similar to "Summoning True Spirit", this boost would become incredibly terrifying.
The most obvious difference between Advanced Professions and Elite Professions isn't actually in Basic Attributes or the number of skills that can be learned, but in these bonuses.
