Hello, I can't find any similar post so I was wondering.
A Sage (p. 72 Ultimate magic) uses INT as a primary ability modifier for his spellcasting abilities and effects related to bloodlines instead of CHA. However most if not all sorcerer exclusive feats require a high (escpecially in higher levels) CHA score. Now this bloodline substitutes CHA with INT only for spells per day, spells save DC and bloodline powers.
Is this an oversight or is a sage sorcerer left out of those feats unless he keeps two very high scores, one of which offers him nothing more but an absolute minimum for feats requirements? This question extends to other ability substitution bloodlines (like Empyreal) as well.
