I am curious why one can not buy a basic skill any any rank level? They are basic after all (pg. 96).
This came up in our game yesterday when I was wanting to buy the Doge and Silent Move skills. The three previous games that we played, I had to make rolls for those two skills (which I did not have, because I am a Imperial Psyker).
So to show that I had attempted those skills and to better justify my purchase of them when it comes time to buy the skills (and to add to the story), I put a check mark next to the name of the skill for each attempted roll, right. Well, those are not available to my character until at least rank 3 (well, doge at least).
Why is this? You would think that after dodging in every combat and still being alive, you can justify buying that skill despite your rank, right?
I am fine with not having my way, but I am curious what the game system reasons are for this limitation?
