List of skills that need "primed"?

[Tynged]

I'm trying to find a list of skills that need at least one point spent on training them before they will increase with use.

Are "level-locked" skills the only ones that need primed? (E.g. Rogue's Dodge @ level 4, Warrior's Parry @ level 10.)

It seems like some skills (Sense Heading, Begging) don't increase until I put the point in. Does the first point simply take dozens of attempts?
