Larian Studios Forums Baldur's Gate III Baldur's Gate III - Build Discussion Knowledge of Ages and Astral Knowledge with skills

Hi All,

I want to make a highly skill non-combat skill based character. I was thinking of going for a Githyanki Lore Bard with some Knowledge Cleric so I can get Astral Knowledge, Knowledge of the Ages and all the skills and expertise that come with being a Bard.

Can someone answer how proficiencies work in conjunction with Astral Knowledge and/or Knowledge of the Age? Also what happens if you use Astoral Knowledge and Knowledge of the Ages on the attribute? How does the stacking work?
