User blog comment:Caudyr/Abilities List From the Author + Translation of Abilities as I go Through the Story.../@comment-124.83.16.225-20151113080923

I don't think Spear King is a Combat Art, Caudyr, but a separate job from Master Spearman.

As for the missing abilities you listed, they may just be abilities that came from the Job (like Combat Arts) rather than abilities he gained from eating monsters. The 100 Blossoms, 1000 Something (Can't remember the exact name) was a skill from his crimson spear, right? So there may be unlisted abilities that come from jobs or magic items.
