I'm a little bit unclear as to when you can train advanced skills. According to the book, skills can only be trained once per rank. But when you take an advanced skill at character creation or afterwords, you don't actually get a point of training in it--you just get the ability to use the skill.
Does that count as your training for that rank? That is, are your basic skills limited to [rank], and your advanced skills limited to [rank - 1]? Or could I use the advance I earned during my first session of play to train my ratcatcher's Animal Handling? If I acquired education by virtue of being a high elf, or channeling by virtue of being an apprentice wizard, can I then choose them as skills to train during the next step of character creation?
Also, the rules say you need to be trained in a skill to take a specialization in it. That seems awkward when it comes to advanced skills (especially for the those careers whose skill lists are almost entirely advanced skills, like the wizard). Must I actually attain that point of training to qualify for a specialization? or is merely having bought access to the skill enough?
