Sages are generally late age focused and really get going around week 4 or 5. I'm just suggesting that early age they could be given something that allows them to compete better. Having natural adbut protection is very nice. I'd like to recommend giving them access to more if not all self spells, and maybe a bonus for casting rituals. They are in lore and in strategy a use knowledge-as-a-weapon choice, allowing them to buff their province with a variety of self spells would be in keeping with this theme. And/or double effect labs/universities.
