For Bards, compared to other transcendent professions, there are quite a number of records in the "New Chronicle." The reason for this is that one of the origins of this profession is rooted in the Northern Lands, which has had many interactions with the Kingdom of Athens.
According to the records, a true Bard is a typical jack-of-all-trades profession, encompassing both divine and non-divine versions.
It's called jack-of-all-trades because most Bards are skilled in swordsmanship, have a basic knowledge of wilderness survival, and can set traps. While they may not have great spiritual or soulful accomplishments, they can also cast some low-level spells. The latter refers to their possession of a unique casting system.
