Does a character receive their innate class bonus without investing in the particular skill?

For example, I create an acrobatic warrior, but opt to not invest any DP into the "Style" secondary skill. The class dictates that I receive +10 to the skill at each level.

During creation does this automatically add 10 to its ability, thereby negating the -30 that would be associated for that check?

Furthermore, if an innate bonus would give you a +5 but the related upper provides a -5 "natural bonus" would the -30 be applied for not having any aptitude, or would you make the roll at zero?

Edit* Additional Question. Since the freelance class adds +10 to 5 different secondary abilities, could he only add those bonuses if he invested in 5 different secondary abilities?

Yes, the character receives the +10 Style bonus at each level, but you still have to have a Base Ability of 5 to be able to use the ability without a -30 modifier.

Nurddude is right and for he other question the answer is no. He can use his boni on the skills he likes without the problem of having invested DP in five of them- The only restriction is with the "knowledge skills", you have to invest DP to benefit of every other bonus you possibly have

I'm a bit late to the party, but the above are correct.

The -30 remains under all circumstances, unless you invest enough DP to raise the Secondary Ability to a minimum of 5. Of course, if after 5 levels you've accumulated a +50 bonus to a certain, untrained skill, your final score will be +20, so it's not like those bonuses are entirely useless if you don't developer the ability further.
