Rank F costs 2 AP

So basically:

• If have 2 AP, it automatically gets to Rank F.
• If not, you get Rank N and 100% Training?

No, in both cases, you will get Rank F.

I was just saying theoretically, if Shamala didn't automatically give you Rank F.

Err, what happens to the 2 AP if you don't have it?

Then you cannot rank it?

Again, currently, because the NPC gives you the skill at rank F, there is no need to "rank" it, therefore you save 2 AP.

If the skill were given at novice, then you'll have to rank it, like normal skills.
